This document has to be filled in with reference to the DM Implementation plan. This means that Deliverables, Milestones and WPs have to be the same as in the DM Implementation plan. The Periodic Report contains 2 parts: - Part I: it is addressed to the coordinator with minimum input from the partners - Part II: it is addressed to each WP Leader and reports a detailed update of each WP activity at task level. The report includes a rough justification of the costs incurred and of the resources deployed by each contractor linking them to activities implemented and justifying their necessity. Finally the report contains information on use and dissemination activities. Reporting period: 30 September 2008 MOMAR Demonstration mission 6 Part I (to be filled by the DM coordinator) In January 2008, the MoMARSAT cruise proposal, core of the MoMAR-D project, was submitted to the French Fleet Committee. After evaluation, the cruise has been prescheduled for the summer 2010. The activity of the MoMAR-D DM was then postponed to cope with this new schedule. The MoMAR-D project actually started in September 2008. This first report does not contain the part II and only presents the updated schedule.

Sarradin (P#7) Executive summary The MoMAR (Monitoring the Mid Atlantic Ridge) initiative aims at providing multidisciplinary time-series data set for hydrothermal systems in the Azores region of the Mid-Atlantic Ridge. This coordinated plan aims at determining the feed-backs between volcanism, deformation, seismicity, and hydrothermalism, and to understand how hydrothermal ecosystems couple with these sub-surface processes, and how this affects exchanges with the ocean. Monitoring at Lucky Strike has started with the MoMARETO (ecology), GRAVILUCK (geodesy), and BBMoMAR (sismology and MT) experiments and will be further implemented in 2008 with the deployment of autonomous temperature probes at selected vents. MoMARSAT will maintain and reinforce these experiments, with a stronger participation of colleagues from other European countries. MoMARSAT is the cruise proposal to implement the MoMAR-D project. We will use the SEAMON technology developed during the ASSEM EC project, with two nodes acoustically linked to a surface buoy that will ensure satellite communication to a land base station. The system will comprise 2 scientific nodes: a geophysical node moored in the Lucky Strike lava lake, and a geochemical/ecological node at the Eiffel Tower vent site. This observatory infrastructure will acquire a synchronized multidisciplinary data set, and allow us to develop solutions for sensor interoperability, shore-sensor interactive communication, data management and dissemination, and public outreach. MoMARSAT comprises two multidisciplinary ROV cruises, the first one is prescheduled in 2010 to deploy the acoustically-linked multidisciplinary observing system at the Lucky Strike vent field and the second one in 2010 to recover it. The study area belongs to the Portuguese ZEE and is part of a planned OSPAR “Marine Protected Area”. Progress of the project MOMAR Demonstration mission 8 In January 2008, the MoMARSAT cruise proposal was submitted to the French Fleet Committee. After evaluation, the cruise has been prescheduled for the summer 2010. The activity of the MoMAR-D DM was then postponed to cope with this new schedule. The MoMAR-D project actually started in September 2008. The first MoMAR-D plenary meeting will be held in early 2009.

Paris VI, boite 100, [email protected] Gabriela Queiroz Centro de Vulcanologia e Avaliação de Riscos Geológicos Universidade dos Açores [email protected] MOMAR Demonstration mission 13 Executive summary The MoMAR (Monitoring the Mid-Atlantic Ridge) project was initiated 10 years ago by the InterRidge Program to promote and coordinate long-term multidisciplinary monitoring of hydrothermal vents in the Azores region of the Mid-Atlantic Ridge This coordinated plan aims at determining the feed-backs between volcanism, deformation, seismicity, and hydrothermalism, and to understand how hydrothermal ecosystems couple with these sub-surface processes, and how this affects exchanges with the ocean. Monitoring at Lucky Strike has started with the MoMARETO (ecology), GRAVILUCK (geodesy), and BBMoMAR (sismology and MT) experiments and will be further implemented in 2008 with the deployment of autonomous temperature probes at selected vents. The MoMAR-D project was selected by ESONET as a demonstration mission to deploy and manage a multidisciplinary observing system at Lucky Strike during one year. Lucky Strike is a large hydrothermal field located in the center of one of the most volcanically active segment of the MAR. Monitoring this field offers a high probability of capturing evidence for volcanic events, observing interactions between faulting, magmatism and hydrothermal circulations and, evaluating their links with the dynamics of hydrothermal fauna. We will use the SEAMON technology developed during the ASSEM EC project, with two nodes acoustically linked to a surface buoy that will ensure satellite communication to a land base station. The system will comprise 2 scientific nodes: a geophysical node moored in the Lucky Strike lava lake, and a geochemical/ecological node at the Eiffel Tower vent site. This observatory infrastructure will acquire a synchronized multidisciplinary data set, and allow us to develop solutions for sensor interoperability, shore-sensor interactive communication, data management and dissemination, and public outreach. The project comprises two multidisciplinary ROV cruises (MoMARSAT), the first one in 2010 to deploy the acoustically-linked multidisciplinary observing system at the Lucky Strike vent field and the second one in 2010 to recover it. The study area belongs to the Portuguese ZEE and is part of a planned OSPAR “Marine Protected Area”. Progress of the project In January 2008, the MoMARSAT cruise proposal was submitted to the French Fleet Committee. After evaluation, the cruise has been prescheduled for the summer 2010. Unfortunately, the preliminary schedule was withdrawn and the cruise proposal had to be submitted once again to the French Fleet Committee. We are waiting for the results of this evaluation and the new 2010-2011 schedule. Nevertheless, the first MoMAR-D plenary meeting took place in March (17-18) 2009 in Ifremer centre de Brest and gathered around 20 scientists and engineers from France, Germany and Portugal. The objectives of this meeting were: 1- The scientific and technological presentation of the different planned experiments by each partner, chair M. Cannat, 2- A description of the operational system by J. Blandin 3- The preparation of interfacing and shore trial step by J. Blandin (see Deliverable 2) 4- The preparation of the data management policy chaired by T. Carval and P.M. Sarradin, deliverable 3. 5- The preparation of the communication plan (regional, national and EU initiatives) by J. Sarrazin (deliverable 4). This meeting allowed proposing a new planning for the interfacing and shore trial step: • Development, adaptations and testing of sensors should be finalized by the end of December 2009. • Integration to SEAMON is planned in January 2010. • A test of the whole system should be carried out by the end of February 2010. • Shipping is planned for May 2010. A first draft of the data management policy (deliverable 3) is circulating among the partners. A final version agreed by everybody is awaited in September 2009.

Objectives: Development, test, validation and deployment for 1 month on SEAMON of in situ chemical analysers for the measurement of Fe and Mn species. Starting points: Existing system deployed in Scottish sea Lochs [Statham PJ et al. 2005] and in hydrothermal setting aboard the WHOI AUV ABE where it was used in plume tracking and vent location. • Progress towards objectives – (short description about Tasks status; each task has to be referred as Task n.m where n is the WP number and m is a progressive number) Task 1-3.1: Manufacturing of two duplicate devices with enhanced electronics for autonomous operation (data logging, self calibration) New datalogger developed and tested in situ to 3600m for short term deployment (~15 hours repeated 5 times), need long term testing. The datalogger has up to 4Gb of data storage and can communicate using RS232 in real time at 1Hz for the data rate. It is low power (24V < 10mA) and has smart electronics to enable valve control and timed data acquisition. Issues with fluidics handling slowdown the development of the sensors. Solution identified and under development and test. contractors involved : NOCS, main research engineer: Dr Cedric Floquet Task 1-3.2: Reagent stability enhancement, improved in situ calibration and fouling reduction techniques PhD student working FT on characterizing the susceptibility to biofouling of the materials used to manufacture the sensors. contractors involved : NOCS, main research engineer: Dr Cedric Floquet Task 1-3.3: Integration to SEAMON Not started. Likely to be RS232 com with 1Hz data rate. System will need power from DeepSea Power and light type battery (24V 32Ah).

Chavagnac and C. Boulart participated to the kick-off meeting of the MoMAR-D program. The two-days meeting took place at IFREMER in Brest in March 2009. - The main scientific objective of the LMTG is to determine the chemical and gas composition of hydrothermal fluids. This requires gas-tight Ti syringes which are not adapted at present for hightemperature fluid. We have therefore ordered Titanium tubing to make Ti canule onto the IFREMER multi-sampler via the mechanical workshop at the LMTG. • Rough Estimation of Major Cost: - Travel to the kick-off meeting: 1711€ - Consummables Ti-material : 3104€ • Overview of the Actual Costs, Type of expenditure Total person-months Personnel costs Subcontracting Travels Consumables Other costs Total Costs Actual costs( Euro) First period 2.0 0 0 1711.00 3104.00 0 4815.00 P#6 Univ.

Cannat Partners involved in the Work DOP, FFCUL, NOCS, CNRS C & F, Univ. Bremen, Ifremer Workpackage objectives and starting point WP1. This workpackage concerns the scientific coordination of the multidisciplinary experiments planned at Lucky Strike as part of the demo mission. All demo partners are involved in this WP. Progress towards objectives – The experiment is still in its preparation stage, because the cruise for the initial deployment of the system has been scheduled provisionally in the summer of 2010 only. We have used the additional year to progress on technological developments made in order to insure the connection of sensor packages to the SEAMON system, but have officially launched the demo at the kick-off meeting in Brest in march 2009. Deviations from the project work programm, and corrective actions taken/suggested (identify the nature and the reason for the problem, identify partners involved) We will not be able to go ahead with the temperature array (partner NOC) we were hoping to deploy to monitor changes in the temperature at diffuse venting areas. Corrective actions: We are looking at other means to get some of these diffuse venting temperature data, including use of a sensor deployed previously in the Gulf of Cadiz.

Bremen, SOPAB Workpackage objectives and starting point (max 500 characters) i) The objective of this WP is to establish and define a data management policy and procedure agreed by all the partners. The principles to be specified are: i) the definition of the data to be acquired, ii) the procedures of control for these data and the definition of metadata in accordance with the standards recommendations on data documentation, and finally iii) the dissemination level. ii) An important task will be to develop links between the MoMAR-D and the data management systems currently used for volcanic and seismic monitoring, and for ecosystem inventory and surveillance, at and near the Azores Islands. To this aim, we have secured the participation of colleagues from the Centro de Vulcanologia e Avaliação de Riscos Geológicos, and from the Department of Oceanography and Fisheries of the University of the Azores. Progress towards objectives – i) Data management principles were discussed during the first meeting in Brest (March 209). A draft document, based on documents issued from Neptune Canada, ESONET and Eurosites, has been written by T. Carval and P.M. Sarradin and is circulating amongst the partners for modifications. A final document (Deliverable 3) agreed by all the partners should be available in autumn 2009. ii) The Centro de Vulcanologia e Avaliação de Riscos Geológicos was present in Brest for the first meeting and presented us their work. Deviations from the project work programme, D3 was planned in March 2009. Data management was discussed during the first MoMAR D meeting in Brest in March 2009.

Colaço Partners involved in the Work DOP, FFCUL, IPGP, NOCS, CNRS F, Ifremer Workpackage objectives and starting point The MoMAR-D demonstration will undertake to comply with the MPA rules and develop a coherent experimental site management plan. This plan will include a set of rules for PI’s, based on the MPA code of conduct and on the InterRidge code of conduct. These rules will aim at minimizing the impact of research on the environment, and at ensuring the compatibility of all the experiments planned. To enforce these regulations, we will make provision in the MoMAR-D demonstration project for a coordinating MoMAR office, probably at Horta (but a centralized ESONET site management office may also be envisioned) and develop formal links with the Portuguese maritime authorities (the Hydrographic Institute), with the MPA managing authorities, and with the Azores Regional Government. Partners from the Centro de Vulcanologia e Avaliação de Riscos Geológicos, and from the Department of Oceanography and Fisheries of the University of the Azores will play a leading role in this task.

Sarrazin Partners involved in the Work DOP, FFCUL, IPGP, NOCS, Univ. Bremen, SOPAB Workpackage objectives and starting point Near real time transmission of data (and video images) from the vents will open new opportunities for public outreach. The public outreach strategy will include press conferences before the cruises, maintenance of a cruise web site, and organization of a live event from the vessel, with video conferences and transmission of live images from the seafloor, participation of journalists interested in making a movie out of this seafloor observatory adventure. Our plan is to have a permanent exhibit, with access to the most recent data and images from the seafloor, at the Oceanopolis aquarium in Brest. Mirror sites and exhibit material could also be set in other large aquariums in Europe. The strategy will cover international to regional initiatives such as the production of a didactic kit, in Portuguese, on hydrothermal vents and seafloor observatories for the different school levels, in connection with in the Azores University. Progress towards objectives – The public outreach strategy was discussed during the first meeting in Brest in March 2009. The communication plan will be available in July 2009 (Deliverable 4).

Sarradin Partners involved in the Work DOP, FFCUL, IPGP, NOCS, CNRS C& F, Univ. Bremen, SOPAB Workpackage objectives and starting point The objective of this WP is to submit a cruise proposal to the French Fleet Committee (D1). This proposal gathers 2 20 days cruises using the French ROV Victor 6000. The first cruise will be dedicated to the implementation of the observatory infrastructure in the Lucky Strike vent field, the second one to its recovery 12 month later. Site studies will be performed during both cruises. Progress towards objectives – In January 2008, the MoMARSAT cruise proposal was submitted to the French Fleet Committee. After evaluation, the cruise has been prescheduled for the summer 2010. Unfortunately, this preliminary schedule was withdrawn and the cruise proposal had to be submitted once again in January 2009. We are waiting for the results of this evaluation and the new 2010-2011 schedule. Deviations from the project work programme The MoMARSAT cruise proposal was submitted 3 times to the French Fleet committee. In June 2009, we have not got any certainty on the scheduling of the cruise in 2010 and 2011. This uncertainty led us to delay the starting date of the MoMAR-D DM (September 2008), and to slow down the shore work. With the new agenda, only the first cruise in would 2010 fit in the ESONET calendar. If the cruise is delayed once again to 2011-2012, the project will be shifted out of the ESONET time schedule setting the question of the future of the project and of the ESONET grant. In such a case, the objectives within ESONET could be reduced to a shore trial of the complete observatory infrastructure. Deliverable D1: Cannat M., Sarradin, P.M., Blandin, J. January 2009.

Monitoring at Lucky Strike has started with the MoMARETO (ecology), GRAVILUCK (geodesy), and BBMoMAR (sismology and MT) experiments and will be further implemented in 2008 with the deployment of autonomous temperature probes at selected vents. The MoMAR-D project was selected by ESONET as a demonstration mission to deploy and manage a multidisciplinary observing system at Lucky Strike during one year. Lucky Strike is a large hydrothermal field located in the center of one of the most volcanically active segment of the MAR. Monitoring this field offers a high probability of capturing evidence for volcanic events, observing interactions between faulting, magmatism and hydrothermal circulations and, evaluating their links with the dynamics of hydrothermal fauna. We will use the SEAMON technology developed during the ASSEM EC project, with two nodes acoustically linked to a surface buoy that will ensure satellite communication to a land base station. The system will comprise 2 scientific nodes: a geophysical node moored in the Lucky Strike lava lake, and a geochemical/ecological node at the Eiffel Tower vent site. This observatory infrastructure will acquire a synchronized multidisciplinary data set, and allow us to develop solutions for sensor interoperability, shore-sensor interactive communication, data management and dissemination, and public outreach. The project comprises two multidisciplinary ROV cruises (MoMARSAT), the first one in 2010 to deploy the acoustically-linked multidisciplinary observing system at the Lucky Strike vent field and the second one in 2010 to recover it. The study area belongs to the Portuguese ZEE and is part of a planned OSPAR “Marine Protected Area”. Progress of the project In January 2008, the MoMARSAT cruise proposal was submitted to the French Fleet Committee. After evaluation, the cruise has been prescheduled for the summer 2010. Unfortunately, the preliminary schedule was withdrawn and the cruise proposal had to be submitted once again to the French Fleet Committee. The cruise is now scheduled in September 2010, on the Pourquoi pas ? with the ROV Victor 6000. Due to logistic constraints of the fleet, the duration of the first cruise was reduced from 19 to 13 days to implement the observatory infrastructure on Lucky Strike. After the meeting in Brest in March 2009 and the final definition of the observatory, this period was used to start the technological work. The design and building of the sensors and nodes is in progress as well as the software adaptation of the sensors to the SEAMON technology. The objective is to start the trial step in Brest in Spring 2010. Shipping is planned during Summer 2010. In parallel, a draft of the data management policy is circulating among the partners (see draft of D3). The MoMAR-D project was presented during the 4th International symposium on Chemosynthetic Based Ecosystems in Okinawa (Jpn), the ESONET All region workshop in Paris, the ESONET Best practices workshop in Brest and the Ocean Biology Observatory Workshop in Mestre (It). The next 6 month period will be devoted to the on shore integration and trial of the system in Ifremer in Spring 2010. D3 and D4 will be finalized before the cruise. The cruise preparation reports (Agreement to work in the Portuguese waters and Technological description of the cruise) will be delivered to the French Fleet in March 2010.

We have build, in parallel, a bench-top set-up necessary to calibrate the methane sensor at atmospheric pressure. We are now in the phase of integrating the different component of the methane sensor using the infrastructure of the LAAS (Toulouse) before starting the first tests of methane detection in water at atmospheric pressure. • • Rough Estimation of Major Cost: 5748€ Overview of the Actual Costs, Type of expenditure Total person-months Personnel costs Subcontracting Travels Consumables Other costs Total Costs Actual costs( Euro) First period 1 396 5352 5748.00 P# 7 Ifremer • Work Performed : A draft of the Data management policy is circulating among the partners and will be finalized before the cruise. The MoMAR-D project was presented during the 4th International symposium on Chemosynthetic Based Ecosystems in Okinawa (Jpn), the ESONET All region workshop in Paris, the ESONET Best practices workshop in Brest and the Ocean Biology Observatory Workshop in Mestre (It).

The PI are Pierre-Marie Sarradin (Ifremer), Jozée Sarrazin (Ifremer) and Grégoire Mercier (Télécom Bretagne). Elaboration of a video processing platform to analyze the temporal dynamics of hydrothermal ecosystems. Located on oceanic ridges, hydrothermal ecosystems are characterized by strong physico-chemical gradients and the presence of a unique fauna, sustained by microbial chemosynthesis. Several studies have shown that the spatial distribution and composition of vent faunal assemblages were strongly correlated to geological, physical and chemical processes at different spatial and temporal scales, but almost no data are available on the temporal dynamics of these ecosystems. The major objective of this post-doctoral research position is to develop a video processing platform to analyze the temporal dynamics of hydrothermal ecosystems. This data along with the abiotic data measured within the vent environment will be analyzed and compared using multivariate statistics. Finally, all the data will be further processed through a GIS that will allow for a graphical representation of all of the observed temporal variations. More specifically, we are looking to answer the following questions : (i) What biological and geological data can be automatically extracted from video imagery to feed the temporal database and (ii) what are the different scales of variations linking environmental changes and the MOMAR Demonstration mission ESONET MoMAR-D 46 3rd Periodic Activity Report, January 2010 dynamics of the fauna in hydrothermal ecosystems ? The acquired data will be used to better understand the influence of abiotic variations on deep-sea animal communities. This post-doc will be one of the first using the new “deep-sea observatory” approach. Expected results may then provide fundamental knowledge on the functioning of deep-sea ecosystems. This project is part of the European programmes ESONET (2008-2011) and HERMIONE (2009-2012) of the 6th and 7th PCRD respectively. • • Rough Estimation of Major Cost: .

MoMAR is a component of the ESONET project (European Seafloor Observatory Network). The ESONET Network of Excellence (NoE, coordinated by R. Person, Ifremer) was launched by the EC in March 2007. The MoMARDemo project is partly funded by ESONET and concerns the 1 year deployment of an acoustically-linked multidisciplinary observing system at the Lucky Strike hydrothermal vent field, with satellite connection to shore. MoMARSAT 1 and 2 are the cruises planned to implement this MoMAR-Demo project. These ROV cruises, one in 2010 and one in 2011, will deploy, then recover, the acoustically-linked multidisciplinary observing system. Lucky Strike is a large hydrothermal field in the center of one of the most volcanically active segments of the MidAtlantic Ridge. Monitoring therefore offers the best chance of capturing evidence for volcanic events, and for interactions between faulting, magmatism, hydrothermal circulations and their impact on the ecosystem at a slowspreading mid-ocean ridge. Our project addresses five main themes and their links : seismicity and hydrothermal activity, vertical deformation of the seafloor, chemical fluxes at Lucky Strike vents, ecology at Lucky Strike vents, and physical oceanography. We plan to use the SEAMON technology, with two nodes acoustically linked to a surface buoy that will ensure satellite communication to a land base station. This system has been developed during the ASSEM-EC project and successfully tested since. Specific solutions will be developped with our ESONET partners for sensor interoperability, shore-sensor interactive communication, and data management and dissemination. This observatory infrastructure will acquire a synchronized multidisciplinary data set, a subset of which will be transmitted to shore in near real time (images of the seafloor, pressure and tilt at seafloor, a subset of fluid chemistry and seismicity data). The rest of the data (fluid chemistry, temperature, oceanographic data, OBS data, microbiological experiments) will be stored locally over the one year duration of the experiment. We will also acquire punctual measurements, and fluid and biological samples, during the 2010 and 2011 cruises. The near real time data will allow us to detect seismic, volcanic or hydrothermal events. We will have the capability to respond to these events by changing sampling rates on some of our sensors, and, if needed, by mobilizing a ship of opportunity. The study area belongs to the portuguese ZEE and is part of a planned OSPAR “Marine Protected Area”. MOMAR-D - Deliverable D1 60 MOMARDemonstration Demonstration mission MOMAR mission 61 61 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD Modifications du dossier par rapport à la version soumise en 2008. La structure du projet reste la même. Il y a peu de changements dans les participants. La stratégie d’instrumentation est inchangée. La stratégie de la première campagne (MoMARSAT 2010) est cependant modifiée puisque nous ne sommes plus dans la position de devoir coordonner cette campagne avec Bathyluck. Toutes les composantes du projet se retrouvent donc dans la même campagne ce qui simplifie le plan de campagne et devrait répondre à la remarque #3 du rapport d’évaluation (reproduit en page suivante). Il en résulte un allongement de quelques jours de la durée sur zone demandée. Remarquons à ce sujet que cette complexité dans notre dossier de 2008 résultait directement du retard d’un an du programme de Bathyluck du fait de l’annulation des campagnes de ROV-Nautile sur Lucky Strike en 2007. Cette annulation (due à divers problèmes techniques de Genavir) a également décalé d’un an la récupération des données des premiers capteurs installés sur Lucky Strike en 2006 pendant les campagnes MoMARETO et GRAVILUCK. Ceci explique, les données n’ayant été récupérées qu’en été 2008, que la valorisation de ces campagnes puisse être vue comme insuffisante (remarque #5)…. Encore que le nombre d’articles publiés récemment pour ces deux projets soit de notre point de vue loin d’être négligeable (cf Fiches de Valorisation en fin de dossier). Il peut être utile de préciser ici que le suivi long terme de la sismicité mené par le projet BBMoMAR a débuté en 2007 et que les données ont également été récupérée en 2008 (cf Fiche de Valorisation BBMoMAR en fin de dossier). De ce fait aucun résultat n’est encore publiable. Les modifications du dossier concernent donc essentiellement sa forme. Nous avons révisée le Document 1 pour mieux faire apparaître les hypothèses à tester et les paramètres à mesurer (remarque #1). Nous avons rajouté une figure et des explications illustrant l’importance de la contribution des données de sismique de SISMOMAR pour la relocalisation prévue de la sismicité et pour la compréhension générale du contexte des circulations hydrothermales de Lucky Strike (remarque #4). Remarquons que les 3 thèses soutenues dans les derniers 6 mois sur ces données sont actuellement en cours de publication (cf Fiche de Valorisation SISMOMAR en fin de dossier). Nous avons également expliqué pourquoi l’activité magmatique actuelle de Lucky Strike, avérée par la découverte pendant SISMOMAR d’une probable lentille magmatique, en fait un site exceptionnel pour l’installation d’un observatoire, et clarifié la stratégie du projet MoMAR qui prévoit également l’instrumentation du site à substratum ultrabasique Rainbow (ceci pour répondre à une remarque d’un des reviewers). Toujours dans le document 1, nous avons clarifié et étoffé la présentation du système SEAMON, des capteurs à connecter, et de l’état de préparation technique du projet (remarque #2). Nous avons rajouté deux tableaux des capteurs. L’un dans le Document 1 (§4) concerne tous les capteurs et permet d’apprécier les développements prévus, l’autre, dans le Document 2 (§5), donne les flux de données transmises et l’énergie requise pour cette transmission pour chacun des capteurs à connecter. Enfin, dans le § 3-3 du Document 1, nous clarifions notre stratégie pour ce qui est des capteurs chimiques (remarque #2). Nous ne dissimulons pas le fait, reconnu dans tous les colloques de prospective sur les observatoires fond de mer, que peu de capteurs adaptés sont opérationnels pour le suivi long terme des fluides hydrothermaux profonds. Notre projet vise donc à combiner suivi long terme avec quelques instruments disponibles, mesures ponctuelles répétées, et développement de quelques prototypes prometteurs. MOMAR-D - Deliverable D1 61 MOMARDemonstration Demonstration mission MOMAR mission 62 62 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD Rapport d’évaluation de la campagne : MOMARSAT Demandeur : Mathilde CANNAT – CNRS IPGP Navire : Pourquoi pas ? L’Atalante Engins : Victor Zone : Atlantique Nord (Azores) Thème : Démonstration de la viabilité d’un observatoire fond de mer pluridisciplinaire sur la dorsale Atlantique (Site Momar Sud Azore) Classement : Prioritaire 2a Avis de la commission: Le projet MOMARSAT-D entend déployer un observatoire fond de mer pluridisciplinaire, non câblé (transmission acoustique puis par satellite) et interactif pour étudier pendant une durée minimum d’un an, un système volcanique actif à l’axe de la dorsale atlantique et son interaction avec l’environnement (zone Momar-Lucky strike). Ce projet, soutenu par ESONET (European Observatory Network), est ambitieux, pluridisciplinaire, et présente une forte composante technologique. Il a valeur de test pour des observatoires fond de mer, non-câblés. (1) (2) (3) (4) (5) Comme indiqué par la précédente commission, la problématique scientifique est abordée en termes très généraux. Le dossier ne contient pas d’hypothèses précises à tester et les différents prélèvements à effectuer ne sont pas toujours clairement justifiés. La commission considère néanmoins que l’analyse croisée de séries spatio-temporelles longues de nombreux paramètres (sismicité, déformation, température et composition chimique des fluides et la dynamique des écosystèmes hydrothermaux) est porteuse de découvertes qui devraient permettre de mieux comprendre le couplage entre la dynamique des écosystèmes, les processus tectoniques et volcaniques, les processus hydrothermaux et les flux thermiques. La commission s’inquiète cependant des nombreux développements, tests et validations d’instruments et de connexions restant à effectuer avant la programmation éventuelle de cette campagne en 2009. En particulier, la commission devra s’assurer que les capteurs géochimiques seront opérationnels à la date de la campagne . La commission souhaiterait d’autre part, être mieux informée sur le type et les flux de données à transmettre en temps réel. Pour cela, un tableau récapitulatif de tous les paramètres à acquérir indiquant leur fréquence d’acquisition, et le volume de données transmises en temps réel par mode acoustique permettrait de se faire une meilleure idée de l’ambition et des garanties qu’offre ce projet. La campagne 2009 présente un calendrier prévisionnel bien ajusté (14 plongées en 19j) pour mener à bien l’installation du dispositif et collecter les données nécessaires sur chaque site. A ce jour, aucun calendrier précis n’est prévu pour la campagne 2010 dont l’objet sera essentiellement de récupérer les instruments et d’acquérir des données complémentaires. Le lien avec la campagne Bathyluck09 n’apparaît pas clairement dans le dossier. Il est parfois difficile de savoir qui fait quoi et où? Des reconnaissances de sites à instrumenter ainsi que l’échantillonnage de fluides sur ces sites apparaissent dans les deux dossiers. Le courrier adressé à la commission par le comité de pilotage ne vient que partiellement lever certaines ambiguïtés. Il est aussi regrettable que les données OBS de la campagne SISMOMAR ne soient pas utilisées pour caractériser la structure de la zone d ‘étude. La valorisation des campagnes précédentes sur le site MOMAR est considérée comme très inégale, particulièrement en sciences de la terre et doit être une priorité du groupe MOMAR. Malgré les réserves mentionnées ci-dessus la commission, consciente des enjeux et du calendrier liés à ESONET, a classé MOMARSAT09 en priorité 2a. MOMAR-D - Deliverable D1 62 MOMARDemonstration Demonstration mission MOMAR mission 63 63 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD DOCUMENT N° 1 MoMARSAT PROJET SCIENTIFIQUE ET TECHNOLOGIQUE Section 1 .Context of the proposal ESONET is an EC Network of Excellence coordinated by R. Person (Ifremer), for the construction of a network of deep seafloor and water column observatories around Europe. The Azores node of ESONET is dedicated to the long-term observation of deep sea ecosystems and of active processes related to seismicity, volcanism, and hydrothermal circulations in the Azores region. It is planned to extend the islands seismic and volcanic monitoring system offshore, and to provide holistic information concerning hydrothermal and seamount habitats, essential for the ecosystem-based management of the region. It will also monitor the movements of deep water masses and the consequences of thermohaline circulation changes in the North Atlantic on climate and on biodiversity. MoMAR (“Monitoring the Mid-Atlantic Ridge”) is a component of the work planned at the Azores node of ESONET, which focuses on active processes at ridge hydrothermal systems. Seawater circulates through the permeable oceanic crust, exchanges chemicals with the surrounding rocks, and is heated to temperatures reaching 400°C. This hot fluid flows up and is expelled at hydrothermal vents, forming black smokers and diffuse vents. Hydrothermal circulation at mid-ocean ridges therefore impacts the transfer of energy and matter from the interior of the Earth to the crust, hydrosphere and biosphere. The unique faunal communities that develop near the vents are sustained by chemosynthetic micro organisms that use reduced chemicals presents in the hot fluids as energy sources. Small active chimney, Lucky Strike (MoMARETO 2006) Environmental instability resulting from active mid-ocean ridge processes (e.g. seismicity) can create changes in the flux, composition and temperature of emitted hydrothermal fluids and consequently can affect the associated faunal communities. Existing data lack of the temporal resolution necessary to understand the natural dynamics of this environment, and, therefore of the global consequences of these processes on the ecosystems and on the transfer of energy and mass from the Solid Earth to the Ocean. MoMAR develops a multiscale and multidisciplinary approach whereby small-scale monitoring experiments, such as chemical and biological recording at individual vents, are nested into larger scale experiments (such as seismic and geodetic networks). Pilot experiments have been conducted over the past few years at the MoMAR vent sites, using autonomous instruments. Two large vent fields are of particular interest, Lucky Strike and Rainbow. The MoMAR-D demonstration mission (led by A. Colaço, University of the Azores, and P.M. Sarradin, Ifremer) is supported by the ESONET NoE and focuses on the Lucky Strike field. MoMARSAT 1 and 2 are the cruises planned to implement the MoMAR-D project. Section 2: The MoMAR study area: setting and summary of previous work The Mid Atlantic Ridge (MAR) near the Azores comprises 4 known hydrothermal vent fields, each with its own specific geological, chemical, hydrothermal, volcanic and biological characteristics (Lucky Strike, Rainbow, Menez Gwen, and Saldanha; Figure 1). It has been the focus of a great number of cruises in the past few years, as part, successively, of the FARA program (French-American Ridge Atlantic), the MARFLUX (MAST II EC program), AMORES and ASIMOV (MAST III EC program) and VENTOX (Framework V), EXOCET/D (Sarradin et al, 2007) and MoMARNET (Framework VI; Cannat et al.) European projects. Most of these cruises have been primarily funded through the French system. The geological-geophysical background of the region is well constrained, as are the general characteristics of the known hydrothermal vents, and the broad diversity of the associated fauna (in terms of megafauna but not for microbial or meiofauna). MOMAR-D - Deliverable D1 63 MOMARDemonstration Demonstration mission MOMAR mission 64 64 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD Simplified bathymetric map of the MoMAR area on the Mid-Atlantic Ridge near the Azores, showing the locations of the principal hydrothermal vent sites that have been discovered so far in this region. BBOBS8 is location of off-axis NERIES broad band OBS (BBMoMAR, Crawford et al, 2007, another instrument is set on Lucky Strike volcano).

AMC =roof of inferred Axial Magma Chamber; grey star: hydrothermal vent field. W(E)BF: West (East) Boundary Fault of the axial valley. Lucky Strike is located at the summit of an axial volcano at 1700m depth. It is underlain by a recentlydiscovered mid-crustal magma chamber (Singh et al., 2006). The site shows sustained levels of microseismicity (Dusunur et al., 2008), and a possible magmatic diking event occurred in 2001 (Dziak et al., 2004). Recent vent fluid chemistry data (Pester et al., 2008) indicate high CO2 concentrations which could suggest degassing of a recently emplaced new batch of magma in the melt lens. Lucky Strike is one of the largest hydrothermal field found along the Mid-Atlantic Ridge. Over 100 hydrothermal vents surround a relatively flat lava lake formation (Fouquet et al., 1995; Ondréas et al., in press). Vent fluid temperatures range from 330ºC in black smokers, to 200-212ºC and even <20ºC in very diffuse emissions (Cooper et al., 2000; Von Damm et al., 1998). Fluid chemistry indicates two distinct sources for the vents in the area (Charlou et al., 2000), suggesting complex hydrothermal cell dynamics. While temperatures appear to be very stable over a time scale of a few years at some vents (i.e., Tour Eiffel, 324±1°C), others show variability of up to 40°C [Statue of Liberty, 202185°C; Sintra, 176-215°C; (Charlou et al., 2000) and personal communication]. Discovered in the nineties (Langmuir et al., 1997), the Lucky Strike vent field has since been the object of many cruises, addressing its geological and geophysical characteristics (Humphris et al., 2002 ; Miranda et al., 2005 ; Ondréas et al., 1997, in press; Escartin et al., 2008). The dynamics of water masses in the area has been extensively surveyed in the summer of 2006 (Graviluck cruise; Thurnherr et al., 2008), showing strong bottom currents and a clear link between high levels of diapycnal mixing in the abyss and the rough topography of the axial valley walls. On most vents, faunal communities are visually dominated by mussel beds of Bathymodiolus azoricus partially covered by microbial mats. The vicinity of active hightemperature chimneys, flanges and cracks are colonized by Chorocaris chacei / M. fortunata shrimp assemblages (Desbruyères et al. 2001). B. azoricus live in symbiosis with microbial endosymbionts (sulphide oxidizing- and methanotrophic bacteria (Fiala Medioni et al., 2002) and are capable of migrating along sulphide gradients. B. azoricus seems to be able to use two of the energy sources present in the hydrothermal fluids (CH4 and H2S) as well as particulate organic matter through filter feeding. The faunal assemblages dominated by Bathymodiolus are present in the cold part of the mixing zone sustained by Recovery of an O2 optode associated with temperature limited hydrothermal input (Sarradin et al., 1999). probes after 12 month, MoMARETO 2006 The first two cruises officially sponsored by MoMAR carried out site survey work, acquiring heat flux measurements (Luckyflux 2003; Lucazeau et al., 2006), and seismic data (SisMoMAR 2005; Singh et al., 2006; Crawford et al., in press). Monitoring was initiated in 2005 with the deployment of an Array of Autonomous Hydrophones (AAH) for regional seismic monitoring (first MARCHE cruise). In 2006, this network was redesigned for a better coverage of the MoMAR area. It has been maintained twice now (2007, 2008), and 3 years of data have been collected. A thesis and 2 papers are in preparation on the first 2 years of data (Simao, Goslin et al.). The 3rd year is being processed now, jointly with the first year of recording of the Lucky Strike OBS network, which is currently operational (check location map in Document 2), and has been operated since 2007 (BBMoMAR). MOMAR-D - Deliverable D1 64 MOMARDemonstration Demonstration mission MOMAR mission 65 65 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD In 2006, the GRAVILUCK (Ballu et al.) and MoMARETO (Sarrazin et al. 2006) cruises deployed two pressure gauges, an oceanographic mooring, and the TEMPO module (video camera, chemical analyzer, temperature probes connected to a SEAMON node) on Lucky Strike. These autonomous instruments could unfortunately not be serviced in 2007, due to the cancellation of the MoMAR ROV cruises to Lucky Strike. The instruments were finally recovered last summer (MoMAR2008-Leg1 cruise) in variable states of corrosion (new pressure probes were then deployed for one more year of recording). Recovered data include one year of oceanographic data and of pressure probe recording, 45 days of video sequences, 18 months of fluid temperature, and 6 months of fluid chemistry (TdFe). We are now processing these data, and assessing the state of each instrument in view of their redeployment during MoMARSAT. Details on this may be found in Section 4. As we write these lines, long (> 1 month) time-series data collected at the MoMAR sites therefore include : the regional seismicity record (AHA array): 2005-2008, the OBS record at Lucky Strike: 2007-2008, and the pressure probe, oceanographic and ecology data listed above (recovered in 2008). All of these data, except the first 2 years of AHA recording, were collected less than 5 months ago and are being processed now. The Bathyluck09 cruise (PIs J. Escartin-A. Deschamp) scheduled in the summer of 2009 will carry out additional site survey, service the OBS array and the pressure probes, deploy temperature probes and perform fluid sampling in venting areas. Further information on the MoMAR cruises may be found on http://www.momarfr.org. Section 3: Scientific objectives and experimental design of the MoMARSAT / MoMAR-D project Lucky Strike is at present one of the most magmatically active segments of the Mid-Atlantic Ridge (MAR). This is important because magmatic activity at slow-spreading ridges is known to be episodic, with short periods of eruptions, and longer periods of faulting of the newly emplaced lava. The duration of these periods is not well constrained, but crustal melt bodies which can produce eruptions have so far only been detected unambiguously in two segments of the MAR: Lucky Strike, and one segment South of Iceland (Sinha et al., 1997). This suggests that volcanic activity may last only a small fraction of the time (a few hundred thousand years) it takes to build the crust at the MAR axial valley. Capturing this short, but critical period is the principal asset of Lucky Strike as a monitoring site. The presence of magma in the crust, near seismically imaged normal faults (Figure below), and in association with high temperature hydrothermal discharge, offers a unique opportunity to study the feed-backs between volcanism, deformation, seismicity, and hydrothermalism, and to understand how the hydrothermal fauna (including microbes) couples dynamically with these sub-surface processes. Basalt-hosted hydrothermal systems such as Lucky Strike are powerful component of the heat exchange machine at slow-spreading ridges. The other component is ultramafic-hosted systems such as Rainbow, where detachment faults leading to mantle exhumation probably control hydrothermal circulation. The present proposal focuses on Lucky Strike as one element of this complex slow-spreading ridge system. The technological achievements of the MoMARsat experiment will be directly transferable to future monitoring of Rainbow-type vents, which is an integral part of the MoMAR plan. Experiments planned at Lucky Strike belong to 5 thematic packages exploring the dynamics of the geosphere, its impact on the characteristics of the hydrothermal fluid (temperature and composition), and on the associated fauna and finally the exchange with the ocean. Each of these have been addressed to some extent in previous cruises and funded projects of the MoMAR “chantier”, through the deployment of autonomous sensors or temporally limited site studies. The MoMARSAT-MoMAR-Demo pilot experiment will represent a significant step towards effective integration of these multidisciplinary experiments in a coordinated seafloor observatory design. The Hydro-MoMAR or MARCHE 3 cruise proposal submitted by J. Perrot and J. Goslin for maintenance of the regional hydrophone array in 2010-2011 has strong links with MoMAR-Demo because it will, if funded, allow us to reinforce our interpretation of local seismicity at Lucky Strike (see § 3.1). 3.1 Thematic Package 1: Seismicity and hydrothermal activity Hydrothermal circulations are primarily controlled by the permeability structure of the substratum, and by the distribution of heat sources. Mid ocean ridges, and particularly slow-spreading ones, are active extensional areas. A long-standing hypothesis (e.g. Wilcock and Delaney, 1996) is that cracks, fissures and faults play a major role to control the spatial and temporal evolution of permeabilities, while magma emplacement within the crust controls the distribution of heat sources. Based on seismic imaging (see Figure below with the eastern axial valley bounding fault imaged at depth very near the axial melt lense), Lucky Strike appears as an excellent place in which to test this hypothesis. Cracking and displacements along faults are expressed by seismicity. Magmatic events such as dyking, and other forms of magma displacement within the crust may also trigger seismicity. Tectonic and magmatic seismic events have specific characteristics, particularly in terms of the stochastic distribution of magnitudes. MOMAR-D - Deliverable D1 65 MOMARDemonstration Demonstration mission MOMAR mission 66 66 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD Seismic monitoring of hydrothermal fields and their surroundings is therefore an efficient method to monitor the tectonic and magmatic events that likely control hydrothermal dynamics. Changes in the dynamics of hydrothermal circulation, on the other hand, are expected to result in variations in the temperature and chemistry of vent fluids. Statistical correlation between variations of the vent fluids, and seismic activity is expected if seismicity does play a role to maintain high permeabilities, allowing for hydrothermal circulation at and near the faults which connect to the crustal melt lens. Relocation of seismic events will also allow us to refine our understanding of the links between specific seismic sources (e.g. the eastern boundary fault in the figure below, or the inferred domain of high temperaure gradient surrounding the low velocity domain of Lucky Strike volcanoe), and the hydrothermal convective system. Evidently, we expect complexities in this signal, revealing the complexities of fluid upflow paths, and of processes in the hydrothermal reaction zone. The link between seismicity and vent fluid temperatures has been used before as a powerful constraint on numerical models of the permeability distribution at hydrothermal sites in the Pacific (Sohn et al., 1998; Wilcock, 2004). We plan to adopt a similar monitoring and modelling approach at Lucky Strike. A comparable combined temperature/seismicity experiment has been carried out over a one year deployment at the TAG hydrothermal field, a Mid-Atlantic Ridge vent field located above a detachment fault (Sohn, 2007a ; 2007b). The experimental design for this thematic package consists in arrays of OBSs (Ocean Bottom Seismometers), and of temperature (T) probes to monitor fluid temperature. Lucky Strike is a large vent field and it is important to be able to check whether the variations detected affect fluids throughout the area, or just locally. Off the shelf autonomous temperature probes are cheap and reliable. This, and the paucity of operational chemical sensors (see §3.3), justifies our choice of temperature as the parameter to monitor at this wider scale. We plan to examine the link between temperature time series and chemical signature of the fluids obtained locally using chemical sensors (see §3.3) and discrete fluid sampling. The local seismicity record will be processed to determine hypocenter locations and to model magnitude and focal mechanisms. Excellent characterization of near site seismic velocity structure is available for this purpose from the SisMOMAR cruise (Seher et al., in prep; Crawford et al., in press; Figure below). We have so far processed only 6 days of passive seismic data (in between shooting times of the SISMOMAR cruise). It suggests that strong temperature gradients, indicative of hydrothermal cooling, surround the axial melt body. The full year of data collected this past summer (BBMoMAR2 cruise) will help to refine this preliminary picture. Interpretation will be reinforced by integrating these local data with the regional hydrophone seismicity record (Hydro-MoMAR or MARCHE 3 cruise proposal submitted by J. Perrot and J. Goslin). The Lucky Strike OBS network does not have the coverage to locate events more than 10 km away from the volcano summit (see location map in Document 2). Event relocation with the AHA array has a low resolution and no depth constrain, but covers >300 km of ridge length north and south of Lucky Strike. It will therefore be used to understand the regional distribution of seismicity, and to determine whether or not a seismic event recorded at the Lucky Strike volcano belongs to a swarm of seismicity extending off the volcano, which typically would be the case for seismicity linked to dike injection events. Tidal forcing on fluid temperatures will also be analyzed, and modeled in terms of crustal permeability (Schultz and Elderfield, 1997).

No vertical exaggeration. Red line shows top of melt lense. The low velocity region underneath is inferred to contain a small fraction of melt (Seher et al., in prep.). One deep earthquake occurred within one km of this low velocity region indicating that lateral thermal gradients are high. Dashed red line shows inferred melt solidus (~1100°C isotherm). Blue arrows show inferred hydrothermal flow paths (from Dusunur et al.,2008). Work on this thematic package is ongoing with the Lucky Strike OBS network (BBMoMAR cruises; PI W. Crawford; location in Document 2), and with the temperature sensors funded by the MoHTESIEM ANR (PI J. Escartin) which will be deployed during the BATHYLUCK cruise this summer (2009). MoMARSAT will maintain these networks of autonomous instruments for one more year (2010-2011). For MoMARSAT, the experimental design will include ~25 autonomous low (<100°C) and high T sensors (<400°C) deployed in vents throughout the study area. A small number of low T probes at diffuse venting areas will be connected to the SEAMON system and data sent to shore on a near-real time basis. The MoMARSAT experimental design also includes 4 autonomous short period OBSs from the University of Lisbon (with Guralp sensors and SEND stations), and 4 short period OBSs from the Parc National INSU. These autonomous OBSs MOMAR-D - Deliverable D1 66 MOMARDemonstration Demonstration mission MOMAR mission 67 67 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD will be deployed around the Lucky Strike volcano, complementing the autonomous Broad-band OBS station operated since 2007 (NERIES program; Pis Crawford and Singh; see location figure in Document 2). In addition, one modified OBS (IPGP) will be connected to the SEAMON system and will transmit a subset of the seismic data via satellite. In the ongoing MoMAR-D preparation phase, solutions for data sampling adapted to our event detection needs are investigated. These solutions involve counting events which have amplitudes above a set of fixed thresholds, which will be chosen using the local seismicity record acquired in 2007-2008. Our objective with this SEAMON-connected instrument is to obtain near-real time information on the level and intensity of seismic activity to serve as a guide for our strategy of shore-sensors interactions (ex: increase sampling rate of fluid chemical sensors or video camera in the event of a seismic crisis). This experiment will use off the shelf technology but requires some work to adapt the modified OBS for SEAMON connection and for deployment by ROV. We will use a standard 3-axis short period instrument, with one processor for data acquisition and storage into the hard drive. A Persistor micro processor is added to interface the SEAMON monitoring node. This interface has been used during the ASSEM EC experiment and is currently being adapted to the OBS specifications. 3.2 Thematic Package 2: Deformation of the seafloor at the Lucky Strike volcano Vertical deformation on active terrestrial volcanoes varies with the type of volcano and with its state in the eruptive cycle. Surface deformation and mass movements are used at terrestrial volcanoes as powerful constraints on models of magmatic and tectonic processes (e.g. Poland, 2006). In a seafloor spreading context, strong extensional tectonics are superimposed on these volcanic cycles. The deformation of active volcanoes in non-marine spreading rift contexts is often in the order of a few centimeters per year, as seen for instance in Iceland (Jouanne et al., 2006; Sturkell et al., 2006). It can, however, also be of the order of 1 meter or more, in dyke injection crisis such as the recent one in Ethiopia (Kendall et al., 2005), or the 1978 crisis in the Asal rift (Ruegg et al., 1979). The tectonic setting at Lucky Strike presents many similarities with that of the EthiopianAfar rift system. The primary hypothesis we wish to test is that vertical motions at a volcanically active mid-ocean ridge could have the same order of magnitude. We also plan to investigate the links between these vertical motions and tectonic and hydrothermal activity by integrating vertical ground motion information with seismic data, and with fluid temperature and chemical data (Thematic Packages 1 and 3). The MoMARSAT experimental design comprises 2 autonomous pressure sensors, which have been deployed at Lucky Strike in 2006 (GRAVILUCK; PI V. Ballu), then recovered and replaced in 2008 (MoMAR2008-Leg 1). These instruments are set at the base and summit of the Lucky Strike volcano (see location map in Document 2) to monitor its deformation by a differential analysis. In addition, we plan to perform a second measurement of the linear array of 10 geodetic benchmarks (also on location map in Document 2), which has been deployed and measured for the first time in 2006. Geodetic results on terrestrial volcanoes indicate that ground deformation tends to be non linear with time. Our permanent pressure gauges will allow us to assess this variability at two locations, while the geodetic network links the two pressure probes and should detect vertical displacements of the order of 1 cm (Ballu et al., 2008). Pressure sensor deployed on the Lucky Strike lava lake (Graviluck 2006) The volcano summit pressure gauge will be connected to the SEAMON system for near real time data transmission. This will require only minor work, because the gauge has been designed initially for connection to this node during the ASSEM EC project. We will also collect data from an autonomous GPS station installed on the BOREL buoy, in order to get the best continuous estimate of the sea surface height above the volcano. This will be obtained after kinematic processing of the data, using a land based GPS station in the Azores. A series of temperature sensors along the mooring line of the BOREL buoy (see § 3.5 Physical oceanography) will be used to convert the sea level variations (buoy vertical movements) into pressure changes and to discriminate in the pressure signal a vertical motion from a sea level change. Finally, pressure data will be complemented by seafloor tilt and vertical acceleration data acquired with the OBM (Ocean Bottom Motion meter) of the University of Bremen. This instrument is an integration of existing parts of the Bremen Ocean Bottom Tiltmeter and the Bremen Ocean Bottom Accelerometer (OBA), which have been deployed for a year at the Logatchev hydrothermal vent field on the Mid-Atlantic Ridge (Fabian and Villinger, 2008). The OBM to be used in Lucky Strike also includes a high resolution absolute pressure-gauge and a temperature data logger. It will monitor long-term sea floor deformations caused by quasi-static processes like tectonics, magmatics, hydrothermal activity or slow mass movements nearby. The data will be MOMAR-D - Deliverable D1 67 MOMARDemonstration Demonstration mission MOMAR mission 68 68 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD collected by a low-power high-resolution data logger. Data will be stored locally. We will also investigate technical solutions to send a subset of these data through the SEAMON system. 3.3 Thematic Package 3: Chemical fluxes at Lucky Strike vents The behavior of chemical species in hot hydrothermal fluid end-members provides critical information on the conditions of fluid rock interactions in the hydrothermal cell (e.g. Charlou et al. 1991). These are susceptible to change with time, due to geological processes (volcanism, tectonics, thematic package 1), or to instabilities inherent to the hydrothermal convective system (Baker et al. 1995). Our planned experimental design aims at a good integration between fluid characteristics and their evolution through time at the scale of the vent field (~1 km2) on the one hand, and the ecological approach developed at the scale of a few meters at the Tour Eiffel vent site (in § 3.4) on the other hand. The difficulty in this thematic package resides in the current lack of reliable sensors for long-term recording of the most critical chemical parameters in deep sea hydrothermal fluids, such as chlorinity, H2S, silica, methane, CO2 or hydrogen content. This limits the potential of chemical time series data for testing hypothesis pertaining to both the small scale of vent habitats, and the larger scale dynamics of hydrothermal convection (e.g. is phase separation (brine and vapor) an active mechanism? can we trace the nature of the reacted rocks and how does it vary with time and from vent to vent?). This difficulty is clearly expressed in the most recent documents generated by the seafloor observatory research communities. It justifies the recent funding of the SENSEnet EC Marie Curie Network (PI D. Connelly) which will promote development and testing of new chemical and biochemical sensors adapted to the monitoring of fluid-controlled deep sea ecosystems. The experiment we plan will receive support from this newly funded network, and be carried out through a collaboration of 3 active European teams. Despite its limitations, this experiment should provide original documentation on the links which may exist between seismic activity and fluid chemistry (§3.1), and between fluid chemistry and faunal distribution at Lucky Strike. Our strategy will combine the use of the few available long term sensors, with fluid sampling and with discrete chemical measurements during the two MoMARSAT cruises (2010 and 2011), enriched by the data obtained during the Bathyluck-2009 cruise. We will also promote testing of new sensors. For the future, we believe that having access to an operational multidisciplinary deep seafloor observatory infrastructure such as the MoMARSAT SEAMON system will be a significant asset for developers of much needed new long-term chemical sensors. We will also deploy an in situ chemical analyser developed at NOC (Southampton) for the measurement of Fe and Mn species. This continuous flow analyser will complement data from the CHEMINI Fe, T and O2 sensors. CHEMINI is a component of the TEMPO module, which we plan to redeploy (it was deployed as an autonomous sensor package during the MoMARETO cruise in 2006, and recovered in 2008), and connect to the Tour Eifel SEAMON node. The NOC Fe/Mn analyser has been deployed in Scottish sea lochs (Statham et al. 2005) and in a hydrothermal setting aboard the WHOI AUV “Abe” where it was successfully used in plume tracking and vent location. Under the MoMAR-D project, two duplicate devices will be manufactured. New electronics will provide enhanced autonomous operation (e.g. data logging and self calibration), and will be interfaced directly with the SEAMON node. Methods for long term operation (e.g. reagent stability enhancement, improved in situ calibration and fouling reduction techniques) will be developed – previous deployments have all been of short duration. The long term deployment of these sensors is novel, and particularly so in a hydrothermal setting. In situ measurements in Eiffel Tower vent, Lucky Strike Other biogeochemical sensors are under development at NOC and, if they pass further trials, will be deployed at Lucky Strike. Most promising is a dissolved Methane sensor (Boulart et al. 2008) developed as part of the MoMARnet project. The detection method is based on refractive index modulation of a modified polymer incorporating molecules of cryptophane-A, which have selective and reversible affinity for methane. The refractive index is determined by surface Plasmon resonance with a limit of detection of 0.2 nM and a range of 1-300 nM. The MoMAR-D work plan for 2009 will focus on the optimization of this sensor (response time, noise, and stability), the adaptation of the electronics, and the calibration under different ranges of pressure and temperature. For the first MoMARSAT cruise, we expect to have a prototype which may be deployed for the duration of the cruise, or used for mapping on the ROV. We will also perform repeated sampling of the hot vent and diffuse fluids and analyze their composition (traces and major elements, stable and radiogenic isotopic ratios, gases) on board the ship or back on shore MOMAR-D - Deliverable D1 68 MOMARDemonstration Demonstration mission MOMAR mission 69 69 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD depending on the elements. We will focus on 5 vent sites of the Lucky Strike field (Tour Eiffel, Nuno, Y3, Statue of Liberty and the vents near Pressure Gauge 1; see location map in Document 2) previously visited during the Bathyluck cruise in 2009. These sites will also be equiped with autonomous temperature probes (thematic package 1). Time-series data from the connected and autonomous sensors and geochemical data on discrete fluid samples will be analyzed jointly in order to link the variability in hydrothermal fluid composition with other parameters, and particularly fluid temperature, and seismicity . To improve the link between the vent site-scale approach described above, and the meter-scale approach of the ecology experiment (§3.4), we will deploy and test an innovative fibre optic temperature sensors array, based on Fibre Bragg Grating (FBG) sensing technology. This temperature sensor system will allow us to monitor fine scale variations in fluid temperatures, actual fluid chemistry being monitored at discrete locations within the array. This will allow us to address the important question of whether (or at which scale) temperature may be used as a proxy for fluid chemistry in fluid-controlled deep sea environments. Distributed oceanographic temperature sensing using FBGs has precedent (Campbell et al., 2000; Mowlem M, 2002) but use in hydrothermal applications is novel. For this pilot study, we will deploy a single, ~10 m-long, fiber optic cable including the temperature sensors based on FBGs. We will purchase an “off the shelf” interrogation unit from Smart Fibres Ltd. After laboratory based trials and calibration (including testing of sensors at pressure), the interrogation unit will be housed in a suitable pressure vessel, with electronics, energy supply and data logger. 3.4 Thematic Package 4: Ecology at Lucky Strike vents Deep-sea hydrothermal ecosystems are extreme habitats, driven by microbial chemosynthesis and characterized by strong endemism. They harbour faunal assemblages dominated by complex animal communities associating microbial producers and secondary consumers that have co-evolved in a constraining environment. Several studies have shown that hydrothermal communities are shaped by dynamic, small- and large-scale geological processes which vary substantially in time and space. The spatial distribution of the fauna can be linked to fluid characteristics including concentrations of chemicals (methane, sulphide, metals) and fluid flow, to the type of substratum and also, to water depth (Sarradin et al. 1999; Sarrazin et al. 1999, 2002, Desbruyères et al. 2000, Le Bris et al. 2003, Sarradin et al. 2007, Cuvelier et al. submitted). Hydrothermal faunal communities also exhibit significant temporal changes that are linked to the temporal variability of their habitats and the ephemeral nature of energy sources (Sarrazin et al. 1997, Shank 1998). Most questions related to the dynamics of these ecosystems and their couplings to geosphere-hydrosphere processes remain unanswered due to the lack of long-term, simultaneous observations. Edifice scale Our recent studies on MAR faunal assemblages have been focussed on describing and characterizing the structure, distribution and habitat of different species at the scale of the Tour Eiffel hydrothermal edifice. This 11m edifice is colonized by different faunal assemblages, visibly dominated by either Bathymodiolus mussels or Mirocaris shrimps. Their spatial distribution appears to follow a systematic pattern on the entire sulphide structure. We want to understand what controls this distribution: is it simply linked to environmental cues such as distance from hydrothermal emissions, or is there a temporal succession pattern (Cuvelier et al. submitted)? We are now looking at year-to-year variations to assess the dynamics of these faunal assemblages, using video imagery acquired during several cruises (1994-2008, Cuvelier et al. in prep). Small scale The semi-quantitative study of 12 small sampling units located on the Tour Eiffel edifice (Sarrazin et al. in prep.; Exomar and MoMARETO cruises 2005, 2006) has demonstrated significant differences of environmental factors, and of the composition, diversity and biomass. Two distinct « assemblages » dominate our samples: low-temperature (mean ∼4-7°C) Bathymodiolus/polychaete assemblages and medium temperature Mirocaris fortunata assemblages (mean ∼ 7°-12°C, Sarrazin et al. in prep). A gradient of chemicals (CH4, total dissolved Fe, pH, total dissolved H2S) is documented in each sampling unit, corresponding to the mixing of the hot fluids with cold seawater. Dissolved copper follows a peculiar behaviour: a significant enrichment is observed in the cold part of the mussel habitats, resulting from the oxidative dissolution of copper sulphide particles in the anoxic / oxic transition zone (Sarradin et al. 2009). Our data also stress that the isotopic composition of some dominant macrofaunal species vary at the scale of a single structure (de Busseroles et al. accepted with revisions), highlighting the complexity of the trophic chain (Colaço et al, 2002). Overall, the food web structure of the Tour Eiffel hydrothermal edifice shows small-scale variations that can be attributable to variations in local food source availability, to environmental conditions or to specific feeding strategies. A strong relationship was observed between δ13C and δ15N isotope signatures and environmental conditions for certain species (B. azoricus, B. seepensis, Mirocaris fortunata, Protolira valvatoides). Our present working hypothesis is that vent fluid characteristics influence microbial production at small spatial scales and thus represent key factors in the variation of local carbon sources at vents (De Busserolles et al. accepted with revisions). Temporal studies The temperature and chemical data collected so far at Tour Eiffel suggest that temperature is a good proxi to describe the chemical conditions (CH4, dissolved Fe, pH, H2S, O2) at the scale of the low temperature vent MOMAR-D - Deliverable D1 69 MOMARDemonstration Demonstration mission MOMAR mission 70 70 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD habitats. Consequently, temperature measurements were used to assess the short term (the studies carried out during the Exomar and MoMARETO cruises have not exceeded 5 days) variability of environmental factors in our twelve sampling units. The results show that temperature variability is different in the different faunal assemblages. We have also identified common periods of variations between temperature probes deployed in different sampling units, suggesting an influence of regional (currents, tides) and local (turbulence, vent fluid flow, etc.) hydrodynamic processes on faunal distribution (Brind’Amour et al. in prep.). Longer time-series are required to link faunal characteristics with other larger-scale fundamental processes such as tectonics, seismicity, or volcanic activity. The dynamics of the fauna and environmental factors at Tour Eiffel were assessed during the MoMARETO experiment, using the autonomous instrument TEMPO (Sarrazin et al. 2007). TEMPO is a long-term imaging module using SEAMON technology and equipped with a deep-sea video camera and two LED lights. A CHEMINI Fe (Vuillemin et al., 2009) in situ analyzer and 3 temperature probes were coupled to the TEMPO module to monitor environmental changes in parallel to community dynamics. Due to technical difficulties, it has not been possible to recover TEMPO in 2007 but it was recovered in 2008 during the MoMAR08 cruise. After 2 years, the structure of the module was little affected by corrosion. The lens of the video camera was clean, validating the efficiency of the antifouling system used. Processing of the data is in progress and will allow us to refine our sampling strategy for MoMARSAT (acquisition frequency, duration of the video sequences, data processing, etc.), and to build a robust data treatment protocol especially concerning the video sequences. 16 T°C and [FeT] µM 14 12 10 8 6 4 2 0 06/09/06 -2 15/12/06 25/03/07 03/07/07 11/10/07 Time The TEMPO module monitored the temporal dynamics of a mussel assemblage at the base of the Tour Eiffel edifice during 45 days. Environmental conditions were acquired simultaneously for a longer period. The module stayed on the bottom during 2 years. Temperature and total dissolved iron concentrations measured in the mussel assemblage. Temperature was monitored during 21 month using a NKE sensor while Fe concentrations were measured during 6 months with the chemical analyzer CHEMINI. For MoMARSAT, our main goal is to acquire longer time-series data to examine the temporal dynamics of faunal assemblages on the Tour Eiffel edifice, in relation to the variation of environmental factors at three different spatial scales: local, edifice, and vent field. More specifically, we plan to: 1. assess the variations of faunal assemblages in terms of composition, diversity and density at different spatial scales (local, edifice, vent field); 2. integrate data from different disciplines into our data base; 3. identify the variations of environmental factors at different spatial scales (local, edifice, vent field); 4. establish the links between faunal variations and environmental factors (conservative or not) at the different scales considered; 5. identify the factors that significantly affect the structure of faunal assemblages at vents through multivariate statistics; 6. continue mapping the distribution of faunal assemblages throughout the years on the Tour Eiffel edifice from 1994 to 2011 (on-going thesis, D. Cuvelier, MARBEF); Two ecological modules, similar to TEMPO, will be deployed, one being connected to the SEAMON East node near Tour Eiffel (located in Document 2). The second one will be used for short term moorings (2 to 6 hours of continuous acquisition). Near real time connection to shore, will allow transmission of a subset of the data (mainly chemical data), with the possibility to modify sampling rates during the experiment. The bandwidth limitation of acoustic transmission is not suitable to transmit video imagery. However, the transmission of still images will be tested at a low frequency. Video will be stored locally to be recovered during MoMARSAT-2011. Image analyses will permit extraction of biological data on dominant species morphology and size structure, estimation of minimal density and biomass as well as collection of data on species behaviour (feeding, predation, movement). Video imagery will also give insights about faunal assemblage variations, succession patterns, growth of visible species (mussels, shrimps, crabs), behavioural and biological interactions such as predation (Sarrazin et al., 1997).The sensors installed on the module will permit the measurements of environmental factors (oxygen and iron concentrations, temperature) within the studied faunal assemblage. MOMAR-D - Deliverable D1 70 MOMARDemonstration Demonstration mission MOMAR mission 71 71 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD To complete and validate the temporal approach, we will pursue the small–scale characterization of the different assemblages colonizing the studied edifice and other assemblages of the Lucky Strike vent field (cf. Thematic packages 1 and 3). The experimental design will rely on the acquisition of time series temperature data by a network of autonomous temperature probes deployed on selected mussel assemblages. In situ analysis will be completed by discrete sampling that will allow the acquisition of other important parameters (dissolved and particulate metal concentrations, methane, organic matter…) to understand the processes controlling the fluid/seawater mixing zone. The speciation of metallic species and their interaction with organic matter will be particularly studied. Fluid flow measurements will be added to the database (Sarrazin et al. submitted). Quantitative sampling of selected faunal patches will validate the data acquired with the video imagery. These samples will also be used to understand the variation of biochemical composition (condition/productivity index) of the animal patches in relation to the environmental factors. The temporal dataset gathered on Tour Eiffel from 1994 on, will be completed with video transects during each cruise following the Cuvelier et al. (submitted) protocol. A mooring with a sediment trap and a current meter will also be deployed close to Eiffel Tower to study the possible influence of the vent fluid on the ocean chemical balance and to tackle the question of the timing of reproduction in hydrothermal organisms. The composition (species diversity), the temporal fluctuation of larval production and the flux of the settling hydrothermal particles emitted by this active vent will be examined. Finally, the characterization, distribution and evolution of the microfauna are an important aim of deep sea hydrothermal ecosystem studies. Microbiological sampling and experiments with colonization devices have been carried out at Lucky Strike, most notably during the EXOMAR, GRAVILUCK and MoMAR2008-Leg 1 cruises. For the MoMAR-Demo / MoMARSAT project, we plan to deploy a set of microbial colonization devices in the immediate vicinity of chemical and temperature sensors, around the Tour Eiffel SEAMON ecology node (also called east node in location map of Document 2). These devices are deployed by ROV and are simple boxes containing standard mineral substrates. 3.5 Thematic Package 5: Physical oceanography Lucky Strike, as most segments of the Mid Atlantic ridge south of the Azores, is a site of active internal wave generation, as well as complicated local circulation influenced by bathymetry and mixing, both near the central volcano and elevated rift valley walls, and in the semi-enclosed deep nodal basins. Oceanographic data collected in 2006 and 2007 during the GRAVILUCK and BB-MoMAR cruises, provide an interesting first view of the internal waves in the area, the flow between the deep basins, and where mixing takes place, in particular in the channel to the east of the Lucky Strike volcano. We are lacking information closer to the volcano summit, which would stride a longer period. We plan to equip the surface BOREL buoy mooring of the SEAMON infrastructure both with a GPS, and with a set of T° (and P) autonomous probes, recording at relatively high frequency (1 minute). This data set will also be used for geodesy (see § 3.2). Current measurements at lower frequency (30') will be an important complement. We will use current meter data which are being recorded near NERIES BBOBS1 (see localisation in Document 2) in view of cleaning seismic data from noise associated with baroclinic tides. We also plan to document the local time variation of water flow patterns and the fluid exchange between the seafloor and the water column close to the Tour Eiffel ecology node. An autonomous CTD/ADCP instrument package has been assembled to that purpose during the EXOCET/D project. This system was deployed and validated for 3 days in 2006 during the MOMARETO cruise. We plan to upgrade this system for autonomous deployment over a longer period (6-12 months). This will involve extending the capability of the existing data logger, augmenting the energy supply, and improving the synchronization between the CTD and the ADCP. A new mechanical frame will be designed that allows for free flushing of the CTD sensors, an open range of the acoustic transducers of the ADCP while all systems being well protected during the deployment and recovery phase. Special care will also be taken in regard to corrosion and biofouling issues. Finally, we plan to complement the dataset recovered during the GRAVILUCK cruise concerning the spatial distribution of mixing over the water column and in the horizontal in the Lucky Strike segment. For this, we will perform fine scale measurements of hydrology and currents (vertical resolution of 1m for hydrology and 8m for currents), and microstructure measurements (i.e. vertical resolution of cm-mm). We plan to use the microstructure profiler VMP6000, and a rosette with CTD sensors and one LADCP. Our main purpose will be to characterize mixing induced by internal tides (the main component of the internal wave field). To this aim we plan to perform repeated profiles at fixed point stations over half a tidal cycle (at least 6h). Section 4: Observatory infrastructure and data management The MoMAR-D experimental design combines autonomous instruments which will store data over the duration of the mission (1 year), and instruments that will be connected to shore via the SEAMON (Sea Monitoring Node) system (Blandin J. & Rolin J.F., 2005). MOMAR-D - Deliverable D1 71 MOMARDemonstration Demonstration mission MOMAR mission 72 72 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD 4.1 The SEAMON / BOREL technology The SEAMON system includes a set of long-term, non-cabled sub-sea observatory components, initially developed by Ifremer during the EU ASSEM project (2002-2004), which have since been upgraded and made more reliable. SEAMON is the generic name of the seabed stations serving a local set of sensors, whereas BOREL (Bouée relais) is the surface data transmission relay. The SEAMON stations are rated for 4000 mwd operations. Each one can provide 8 kWh, allowing for the sensors operation and for a daily data transmission of ca. 40 kbytes. You will find a table of connected instruments with indications of the volumes of transmitted data and energy requirements in Document 2. The main components of SEAMON are the following: COSTOF (Communication and Storage Front-end). This electronic unit serves a set of local sensors by providing them with data storage, communication channels and optionally energy. COSTOF communicates with the ROV via CLSI (see below), and with a ship, and the BOREL buoy via acoustic modems. The COSTOF robustness and modularity rely on the use of a low power field bus (CAN) linking a set of simple identical boards, each board devoted to one sensor. The measurement sequencing is left to each sensor. This way, a COSTOF failure does not prevent data acquisition at the sensor level. Conversely, data duplication at the COSTOF level is a safety factor in case of sensor damage. CLSI (Contact-Less Serial Interface) is a small device made of two halves, allowing serial communication between two units, without electrical connection. If one half is connected to a ROV, and the other half to the COSTOF, communication can be established between the ship and any connected sensor. It is very useful just after the ROV has completed a sensor mechanical installation, to check or fine tune its functioning before the ROV leaves the area. BOREL The BOREL buoy is the data transmission relay between the SEAMON stations and the Iridium satellite constellation. It is moored within acoustic range of the SEAMON stations and is composed of two identical independent data transmission channels. Channel 2 can be activated from shore in case of a failure of channel 1. Each data transmission channel is powered independently and comprises an acoustic modem, a control electronics and an Iridium modem. The communication is bi-directional and BOREL supports three data transmission modes: periodic (typical rate 6 hours), triggered by events detected on the seabed, and triggered from shore. BOREL has now been used for two years in the Mediterranean Sea, where it is moored at 2000 m depth. The Mediterranean mooring will be modified for MoMAR-D to take into account the sea conditions prevailing in the mid-Atlantic. Its position and the local sea/wind state will be monitored throughout the experiment. The robustness of this mooring is clearly one of the technical challenges of the MoMAR-D experiment. Acoustic data transmissions For five years now, successive SEAMON/BOREL systems have been using the same type of acoustic modems. Their reliability has now reached a satisfying level, but their energy requirement per transmitted bit (a key parameter for non-cabled observatories) can probably be significantly lowered. Ifremer is currently working on this issue. This work started in 2007 with a selection of five modems available on the world market. Among the selection criteria, the lowest energy necessary to transmit 1 bit at a given distance was sought. In 2008, three of these five modems were tested at sea, between a sub-sea station at a depth of 2200 m, and the R/V L’Europe. This test demonstrated that the latest modems require at least 15 times less energy to transmit one bit in those conditions, than the ones used on SEAMON until now. Longer term tests of the two best modems are planned in 2009, between the 2200 m-deep subsea station and a relay buoy. The MoMARSAT experiment will directly benefit from these improvements. 4.2 Configuration of the nodes Two SEAMON nodes will be deployed in the Lucky Strike vent field (see location in Document 2). A Table of the connected sensors, the volume of data transmitted an dthe energy required for transmission at each node is provides in Document 3: • SEAMON-East will be primarily devoted to thematic experiments 3 (Chemical fluxes), 4 (Ecology) and 5 (Physical oceanography). It will connect a video camera, chemical sensors and the CTD/ADCP package. T-probes connected to this station will also provide time-series data for experiment 1 (Seismicity and hydrothermal activity). This node will be moored at the base of the active hydrothermal edifice Tour Eiffel, near the location of the autonomous TEMPO station deployed during the MoMARETO cruise. • SEAMON-West will be primarily devoted to thematic experiments 1 (Seismicity and hydrothermal activity) and 2 (Seafloor deformation). It will connect the pressure probe, one OBS, and the OBM. This second node will be moored in the western part of the lava lake, near the present location of the pressure probe installed since 2006. MOMAR-D - Deliverable D1 72 MOMARDemonstration Demonstration mission MOMAR mission 73 73 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD Sketch of the MoMAR-D experiment The BOREL buoy The MoMAR-D project includes pre-cruise integration of these sensors to the monitoring node, followed by their qualification and validation prior their deployment during one year. Underwater connection devices The sensors to be connected underwater will use a low cost connection device (CdC,) specially developed and validated during the ASSEM project. Data storage Each connected sensor will also independantly store data over the 12 months duration of the project. The Ecology package (TEMPO) and the pressure gauge already have tested operational SEAMON connections. Development will be carried out for the connected OBS (IPGP), the OBM (Univ. Bremen), the NOC continuous fluid flow analyzer and the CTD/ADCP mooring. Other sensors will be deployed as autonomous instruments, storing data that will be recovered at the end of the 1 year experiment. The table in section 4.4 presents a list of the sensor to be implemented during the cruise. Biofouling Biofouling is a major issue in the vent ecosystem. Biofilms form on every available surfaces and trap the mineral particles emitted by the hot fluids. The method used successfully (Exomar, 2005 and MoMARETO, 2006) for preventing bio-fouling on the lens of the TEMPO video camera and on an Aanderaa oxygen optode relies on localized microchloration. This method does not modify the image, and the concentrations of chemicals released are negligible. Feasability The SEAMON system has been deployed previously in the following sea-bed monitoring applications: • 2004, Gulf of Corinth, 380 m, 7 months, seismicity, geodesy - Ballu et al., gas emissions (CH4, O2), • 2004, Finneidfjord (Norway), 25 m, 4 months, slope stability - Strout et al. (pore pressure, T°C), gas emissions (CH4), • 2005-2007, Var canyon, 2000 m, 24 months, particle dynamics - Khripounoff et al. (dissolved O2, turbidity, current), • 2006, Bay of Douarnenez, 25 m, 2 months, experimental polluting shipwreck monitoring – Marvaldi et al. (ADCP, fluorimeter hc, turbidity, dissolved O2, CTD), • -2006-2008, Nice slopes, 35 m, 20 months, slope stability – Sultan et al. (pore pressure, T°C), • -2006-2008, Azores hydrothermal vent “Lucky Strike” (autonomous SEAMON TEMPO module), 1700 m, 18 months, hydrothermal ecosystems study – Sarradin et al. (video camera, dissolved Fe, T°C ), • -2007-2008 and 2008-2009, offshore Marseille, 20 m, 2 and 3 months, contaminants re-suspension – Gonzalez et al. (ADCP, turbidity, passive organic contaminant concentrator), • A modified version of the TEMPO-SEAMON node is presently connected to the VENUS cabled observatory in Canada. Feasibility of MoMAR-D and MoMARSAT also depends on the availability of ships, ROVs, on access to supporting shore-based infrastructures, and on additional funding from national agencies. The strong support received at the regional level is an asset of the project, allowing us access to facilities in the Azores, such as a GPS station at the University of the Azores for differential GPS location, and, most notably, the facilities in Faial Island. LabHorta is a laboratory facility that expands the capacity of research cruises for the experimental studies of the biology, physiology and behaviour of deep-sea hydrothermal vent fauna. The University of the Azores also maintains an Oceanographic instrumentation and Calibration Laboratory, which is dedicated to insure the operationality and precision of several types of oceanographic equipments. Last but not least, 2 MOMAR-D - Deliverable D1 73 MOMARDemonstration Demonstration mission MOMAR mission 74 74 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD research vessels are based in the islands and could allow a quick response to an event occurring at Lucky Strike during the 12 month of the observatory deployment. 4.3. Data management and scientific integration Data management and dissemination is a key task in the implementation of a multidisciplinary long term observatory. Principles of data management and dissemination will be discussed within the MoMAR-D project in the spring of 2009, to obtain a formal participant agreement. The data management policy and procedure will be defined taking benefit of the experience gained by Neptune Canada. The principles to be specified are: i) the definition of the data to be acquired, ii) the procedures of control for these data and the definition of metadata in accordance with the standards recommendations on data documentation, and finally iii) the dissemination level. The framework for this discussion is defined in the ESONET Description of Work. Data management procedures will be fully compatible with international recommendations and standards in order to improve interoperability with other systems and to ease comparison with other datasets: ISO standards for metadata, COI/WMO standards for quality flag scale. SISMER will collect, flag and archive the data (in real time and after the recovery). Data will be made available online according to ESONET data policy and European directives. Data will also be forwarded to data centers involved in the ESONET project in order to be permanently archived and distributed. The MoMARSAT cruises will also produce data from autonomous sensors or complementary site studies. These data will be archived and part of the demonstration will be to design appropriate procedures for control and dissemination of these data. Biological site survey data acquired during the cruises will be available through the BIOCEAN database. A GIS database and interface is being implemented for the MoMAR sites with support from the ANR Mohtesiem (J. Escartin), and MoMARnet projects. It now contains all the available dive data and a subsequent subset of the geophysical data collected so far in the MoMAR area. It will be maintained by the MoMAR-Demo project and adapted to fit the ESONET policy on data property and accessibility. An important task will be to develop links between the MoMAR-Demo data management system, and the data management systems currently used for volcanic and seismic monitoring, and for ecosystem inventory and surveillance, at and near the Azores Islands. To this aim, we have secured the participation (to MoMAR-Demo, not involved in actual MoMARSAT cruise work) of colleagues from the Centro de Vulcanologia e Avaliação de Riscos Geológicos, and from the Department of Oceanography and Fisheries of the University of the Azores. Scientific integration of the data is a key point of this project. Data treatment will be done first at the Thematic package level, followed by a second step to understand the links and common sources of variability at the different scales studied. Data coming from all thematic packages will be analyzed to study the links between environmental changes and community structure and dynamics. This final data integration step will be the subject of a workshop, gathering all scientists involved in the MoMAR-D proposal. The Table below lists the data and sample sets which we plan to acquire, their timing of acquisition, the relevant thematic packages, and the corresponding tools or sensors. Instruments which we plan to connect to SEAMON are listed in bold. Those which will require some adaptation prior to the cruise are listed as “prototypes”.

The near real time data will serve both as support for scientific interpretation, and as an indicator that an “event” is occurring. Events at Lucky Strike may be volcanic (eruption, underground dyking event, or rapid degassing of the magma chamber), tectonic (displacement along axial faults), or hydrothermal. Understanding the impact of these events on biological communities (micro organism bloom, composition, structure,) is one of our key objectives. Our array of connected sensors will be able to detect all, or most of these events. Rapid response is particularly indicated in the case of a volcanic event, as it has been shown to profoundly modify vent ecosystems, with a variability of hours, days, and weeks (Haymon et al., 1993; Shank et al., 1998), probably extending to years. Our rapid response capability at Lucky Strike will be limited, but enough to open exciting opportunities: 1- the SEAMON capability for interrogating sensors and modifying certain parameters from shore shall allow us to modify data sampling rates for a given sensor, if an event is detected; 2- we also plan to take advantage of the access to the Azores-based RV Archipelago, which unfortunately does not allow for ROV-type intervention, but can perform water column sampling, and recover acoustically released devices; 3- finally, should evidence for a major event be collected, we will actively search for a larger ship of opportunity, with ROV capability (for example the new ROV-equipped Portuguese). 4.4. A regional managing strategy for the Azores node The growing interest and the increased number of science activities at the MoMAR vent fields have led the Portuguese and Regional administration to propose, in 2006, the area as a Marine Protected Area (MPA) within the OSPAR network. This proposal followed a workshop organized in Horta in 2002 (Santos et al, 2003). The Lucky Strike vent field is identified in the MPA proposal «with the aim of promoting knowledge, monitoring and conservation of an area that best represents species, habitats and ecological processes in deep-sea hydrothermal vents in the OSPAR area, while enabling sustainable scientific research and promoting education and environmental public awareness and interest ». MoMAR-Demo will undertake to comply with the MPA rules and develop a coherent experimental site management plan. This plan will include a set of rules for PI’s, based on the MPA code of conduct and on the InterRidge code of conduct. These rules will aim at minimizing the impact of research on the environment, and at ensuring the compatibility of all the experiments planned. In this context, we plan to devote one MoMARSAT dive in 2011 to clean the area around our experimental network of the abundant non-native material left over the years of scientific work. Acquired video imagery data will be used as the background of the site management objective. MoMAR-Demo will for the greater part be financed by the participating institutions and their respective national funding agencies. This partnership, together with the Portuguese maritime authorities, MPA authorities, and the Regional Government of the Azores, will form the embryo for the future Regional Legal Entity of the ESONET Azores node. Section 5: Public outreach Near real time transmission of data (and video images) from the Lucky Strike vents will open new opportunities for public outreach. Our plan for the MoMAR-Demo is to fully use these opportunities, both in the direction of the general public, and toward school and university students. The dissemination plan will be designed at the beginning of the project in collaboration with the dedicated ESONET Workpackage. It will cover international to MOMAR-D - Deliverable D1 75 MOMARDemonstration Demonstration mission MOMAR mission 76 76 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD regional initiatives such as the production of a didactic kit, in Portuguese, on hydrothermal vents and seafloor observatories for the different school levels, in connection with in the Azores University. Taking advantage of the contacts made in 2006 with the GRAVILUCK and MoMARETO cruises, we will also start a collaborative project with the European Aquarium Network. The public outreach strategy for the MoMAR project will be designed in close collaboration with Oceanopolis, with the Public Relation Offices of Ifremer, CNRS, NOC and the other participating institutions. This strategy includes press conferences before the cruises, maintenance of a cruise web site, and organization of a live event from the vessel, with video conferences and transmission of live images from the seafloor such as the nuit des abysses done during MoMARETO (Sarrazin et al.). We also will seek the participation of journalists interested in making a movie out of this seafloor observatory adventure. The project web site will allow an access to the “real time” data edited and commented by scientists. Our plan is to have an exhibit, which will last over the 12 months of the MoMARDemo, with access to the most recent data and images from the seafloor, at the Oceanopolis aquarium in Brest. Mirror sites and exhibit material could also be set in other large aquariums in Europe. Section 6: Workplan Due to weather constraints, submersible cruises to the MoMAR area can only take place in the summer (May to August). Deployment is planned for the summer of 2010, which will leave us time to achieve the physical integration of the sensors on the SEAMON nodes. To comply with ESONET need for visible results prior to the end of 2010, we have defined the MoMAR-D work plan with a core period (January 2009 to December 2010) after which we will report on all technological and integration aspects, as well as on the test of the system at sea during the first MoMARSAT cruise. We will then produce an updated final report in December 2011, after the MoMARSAT–2 cruise, integrating the full results of 1 year operation of the system. Seven Milestones have been identified throughout the MoMAR-D project, corresponding to crucial steps: submission of the cruise proposal (M1), agreement on a data management policy (M2), on shore integration and trials (M3), system deployment (M4), intermediate report to ESONET (M5), system recovery (M6), final report (M7).

The ESONET project has provided the framework for the MoMAR-Demo project within its internal call on Demonstration mission. The MoMARSAT cruises are proposed to carry out MoMAR-D. This proposal builds upon over 10 years of work on hydrothermal systems of the Azores area, much of which was achieved with combined European and national funding. Two EC-FP6 projects directly concerned MoMAR: one for development of observatory sensors (EXOCET/D; Sarradin et al., 2007) has provided support for the MoMARETO cruise and the deployment of the TEMPO SEAMON module at Lucky Strike; the other is a research and training EC network that funded 13 PhD and 3 post docs for MoMAR research (MoMARnet; Cannat et al., 2006). A more recently funded FP6 project, NERIES, funds the installation for 3 years of the broadband Ocean Bottom Seismometer near Lucky Strike (part of BBMoMAR project; W. Crawford and S. Singh). More recently, the SENSEnet Marie Curie Research network, coordinated by D. Connelly and focused on sensor development for deep sea hydrothermal environments, has been selected for funding and is now in negociation stage with the EC. This project will support students and researchers involved particularly in Thematic Package 3 of MoMARDemo. MOMAR-D - Deliverable D1 76 MOMARDemonstration Demonstration mission MOMAR mission 77 77 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD National funded initiatives in the MoMAR “chantier” have mostly been French so far (Ifremer, INSU, ANR), with a significant Portuguese contribution (the Marine Protected Areas initiative, the Lab-Horta biological facility), and UK involvement in Electro-Magnetic site surveys at MoMAR vents. Scientific and technological discussions within EXOCET-D and MoMARnet, and during the initial stages of ESONET, have strengthened this UK participation (attracting new partners for fluid chemical studies), and have allowed us to find German partners for the geodetic aspects of MoMAR-D. Part of the MoMARSAT experiments will be funded through the DEEP OASES project (Thematic package 4, D. Desbruyères). The project is supported by the Ifremer programs « Ressources minérales, énergétiques et écosystèmes profonds” (L. Lemoine), and by the GDR ECCHIS. It is also supported by INSU through the MoMAR chantier, and the “Soutien campagnes” for travel and freight expenses. Part of the MoMAR-D project (Thematic package 4) was submitted to the FP7 call ENV.2008.2.2.1.2. Deep-Sea ecosystems within a proposal linked to the actual HERMES project (HERMIONE, PI P. Weaver, contract signature). An important aspect of the MoMAR-D project is to develop interoperability of sensors and data management solutions, within ESONET and internationally. For this last aspect, we will take advantage of the opportunities offered through the Memorandum of Understanding that links Ifremer and the Univ. of VICTORIA, the leading institution behind the VENUS cabled observatory and the NEPTUNE Canada seafloor observatory initiative. An observing module called TEMPO mini was connected to the Venus coastal network in the autumn 2008 and will be recovered in February 2009. After this first coastal trial allowing to validate the instruments and the interfaces with the cable, the module will be moored at the Endeavour hydrothermal node of NEPTUNE in Summer 2009 as a part of an integrated multidisciplinary study (contact Mairi Best [email protected]). Our technical objective is to learn from the larger Neptune initiative, and our scientific goal is to compare the temporal dynamics of hydrothermal fauna assemblages between a slow spreading ridge (Lucky Strike), and an intermediate spreading ridge (Endeavour segment of the Juan de Fuca ridge).

MOMAR-D - Deliverable D1 78 MOMARDemonstration Demonstration mission MOMAR mission 79 79 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD DOCUMENT N° 2 MoMARSAT DESCRIPTIF DES CAMPAGNES 2010 et 2011 1- Infrastructure et déroulement du projet Les objectifs des campagnes MOMARSAT peuvent être résumés ainsi : - Etude temporelle des processus actifs sur le site hydrothermal Lucky Strike, - Déploiement d’un observatoire multidisciplinaire non câblé pourvu d’un système de transmission de données quasi-temps réel, - Opération de cet observatoire pendant douze mois. Pour répondre à ces objectifs, le projet MOMAR-Demo est structuré en plusieurs tâches sur une durée de 36 mois (voir tableau en Section 6 du Document 1). Les campagnes à la mer en 2010 et 2011 correspondent aux phases de mise en place et de récupération de l’observatoire et à l’acquisition de données complémentaires sur site. Le projet est financé partiellement dans le cadre du WP4 « Missions de démonstration » du réseau d’excellence ESONET (MoMAR-Demo, A. Colaço et P.M. Sarradin ; voir détail du plan de distribution des fonds alloués par ESONET dans la Fiche Synthétique 2). MoMARSAT repose sur un parc de matériel en grande partie existant (Cf Tableau du Document 1 § 4.3). Le réseau d’observation utilise le système SEAMON – BOREL et les capteurs associés. L’année 2009 sera consacrée à l’adaptation des stations et des capteurs et à leur qualification. A partir des données de bathycélérimètrie disponibles sur la zone, une étude de propagation acoustique du site sera effectuée, étude qui déterminera la position optimale de la bouée par rapport aux stations. L’intégration du système dans sa totalité (y compris la gestion des données) et les tests d’endurance à terre auront lieu au second semestre 2009. En parallèle, la politique de mise à disposition et de traitement des données sera définie et acceptée par tous les participants au projet. La tâche « communication vers le grand public » suivra un calendrier analogue, aux échelles nationale et européenne. Afin de valider, et de valoriser les séries temporelles, il sera nécessaire de disposer d’une part de mesures ponctuelles des mêmes paramètres sur une zone plus large, et d’autre part de mesures ponctuelles de paramètres qu’on ne sait pas mesurer sur le long terme. Ces mesures ponctuelles sont indispensables pour les expériences sur l’écologie, sur la chimie des fluides, et sur la géodésie. Pour l’écologie, l’acquisition de données sur site sera focalisée sur Tour Eiffel et aura lieu pendant les 2 campagnes MOMARSAT. Pour la chimie des fluides, l’échantillonnage concernera plusieurs sites sur tout le champ hydrothermal et débutera en 2009 durant Bathyluck afin d’obtenir une série sur 3 ans. Pour la géodésie, nous prévoyons une seconde campagne de mesure du réseau de repères (voir Figure en fin de Document 2) en 2011. Nous privilégierons les plongées longues (≥ 24 h), permettant de couvrir les objectifs de plusieurs manips, sauf pour les premières plongées de mises en place du dispositif SEAMON en 2010, qui doivent être rapidement suivies de tests. Nous utiliserons si nécessaire la navette ascenseur et nous organiserons le planning de ces plongées pour que les échantillons fragiles (biologie en particulier) soient prélevés peu de temps avant la remontée. 2- Campagne 2010 La première campagne du projet en 2010 permettra la mise en place de l’infrastructure de l’observatoire (bouée BOREL et nœuds SEAMON) et des capteurs connectés (environ 6 jours). Cette mise en place sera précédée d’une reconnaissance rapide et du marquage des zones à instrumenter (1 jour). La récupération et le redéploiement de l’instrumentation autonome qui aura été mouillée durant la campagne Bathyluck 2009 prendra environ 6 jours: récupération et redéploiement de 2 jauges de pression, des colonisateurs microbiens, et du réseau de capteurs autonomes de T° des fluides sur 5 sites hydrothermaux du champ Lucky Strike (Y3, Statue of Liberty, Tour Eiffel and Nuno-Hélène ; cf Figure en fin de Document 2). Environ huit jours seront en outre nécessaires pour l’acquisition de données d’écologie et de chimie des fluides afin de valider les séries temporelles et de les situer dans un contexte plus général. Enfin, les temps de reconditionnement du ROV entre les plongées seront consacrés à des opérations de pont : récupération et redéployement de 10 OBS (4 INSU, 5 portuguais, 1 BBOBS-IPGP), et manips d’océanographie physique. Les opérations à mener durant la campagne MoMARSAT 2010 sont donc les suivantes : 1. Reconnaissance rapide et marquage des zones à instrumenter 2. Mouillage des Nœuds (free falling + déplacement par VICTOR) et de la bouée BOREL, mise en place des capteurs connectés à Seamon, tests de fonctionnement, maintenance éventuelle 3. Acquisition de données sur sites (chimie, écologie) 4. Déploiement des capteurs autonomes 5. Travaux de surface MOMAR-D - Deliverable D1 79 MOMARDemonstration Demonstration mission MOMAR mission 80 80 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD 2-1 Reconnaissance du champ, choix et marquage des zones à instrumenter Les données de microbathymétrie et les mosaiques photos acquises sur le site avec le Module de Mesures en Route du ROV VICTOR durant les campagnes MoMARETO et MoMAR2008-Leg1 (Cartes en fin de document 2) permettent une navigation et une recherche des cibles très rapides. Les zones à instrumenter (Tour Eiffel, sites Est et Nord Ouest, lac de lave) seront repérées par des marqueurs passifs. L’étude de propagation acoustique sera validée sur site. Une reconnaissance petite échelle de l’édifice Tour Eiffel sera ensuite effectuée suivant le protocole développé par Cuvelier et al, (soumis, DSR). Cette reconnaissance permettra de marquer les zones d’études et d’acquérir la donnée vidéo nécessaire à l’étude temporelle de l’édifice (Thematic package 4). L’ ensemble de cette reconnaissance prendra 24h (1ère plongée). 2-2 Mouillage des Nœuds et de la bouée. L’infrastructure du réseau sera mouillée immédiatement après la plongée de reconnaissance. Les nœuds seront mouillés en « free falling » depuis le navire. Le mouillage comprend un lest de descente, une flottabilité additionnelle et une balise/ largueur BUC. Sur le fond (Plongée 2), les mouillages seront déployés et positionnés par le submersible. La durée approximative pour le mouillage est de 2 h pour chaque nœud. Le positionnement sur le fond de chaque nœud par Victor durera entre 4 et 6 heures. Le mouillage Borel comprend un lest de 1600 kg, une ligne de mouillage de 1700 m (Polypropylène, Nylon) et la bouée équipée (1300kg, diamètre 2.3 m). La stratégie de mouillage comprend la mise à l’eau de la bouée à 2000 m du point, le filage de la ligne de mouillage en remontant au-delà du point, et le largage du lest. La durée estimée de mise en place de la bouée est de 6 h. Le mouillage de la bouée sera effectué après la seconde plongée, durant le reconditionnement de Victor. 2-3 Mise en place des capteurs connectés à SEAMON, Une contrainte technique importante réside dans le déploiement des capteurs par Victor et leur connexion aux nœuds SEAMON (Nœud Est « écologie », Nœud Ouest « géophysique » ; cartes en fin de Document 2 et liste des capteurs à connecter dans le tableau du § 2.8 de ce Document). Cette opération a déjà été réalisée par le submersible habité Thetys (HCMR) en 2004 dans le Golfe de Corinthe. L’étape préalable de reconnaissance et de marquage des zones à instrumenter est déterminante pour la mise en place des capteurs sur ces sites à topographie très perturbée. Pour faciliter le déploiement, certains capteurs pourront être connectés à leur nœud d’accueil sur le fond en utilisant des connecteurs CdC. La durée de mise en place de chaque capteur par le ROV a été estimée entre 3 et 4h, soit environ 12h pour le nœud Ouest (3 capteurs, tableau au § 2.8) et 20h pour le nœud Est (Plongée 3). Les tests conduits pendant cette phase de déploiement du dispositif pourront conduire à récupérer tout ou partie du système pour réparation ou remplacement. Ceci pourrait dans le pire des cas représenter 2 plongées supplémentaires (environ 56h). Nous prenons un pied de pilote intermédiaire de 28h (Plongée 4 et reconditionnement ROV), étant entendu que le fonctionnement du système SEAMON a déjà été testé à de nombreuses reprises (cf § 4.2 du Document 1). 2-3-1 Ecologie : Tempo, précurseur du Nœud écologie, a été mouillé pendant la campagne MoMARETO. Tempo est constitué de 2 modules : le module énergie rassemblant les composants SEAMON et le module capteurs relié par un câble de 15 m. Lors du mouillage, le module capteur est logé dans le module énergie. Victor positionne le module énergie sur le fond à proximité de la zone d’étude. Il déploie ensuite le module capteurs à portée optique de l’assemblage cible. Les paramètres de la caméra (cadrage, zoom et focus) sont réglés depuis la surface à l’aide d’un lien CLSI. Finalement, la canule de prélèvement de l’analyseur in situ, associée à 3 sondes de températures autonomes et une optode à oxygène, est mise en place dans l’assemblage. Le bon fonctionnement de l’ensemble est vérifié sur place via le lien CLSI. 2-3-2 Etude des flux chimiques : Le module CTD/ADCP et le capteur Fe / Mn, seront connectés sur le fond au Nœud Est. Le module CTD/ADCP sera positionné à la base de Tour Eiffel, l’analyseur de Fe/Mn sur une émission diffuse à proximité du module TEMPO. 2-3-3 Sismicité. Le dispositif comprendra un OBS 3 composantes acquis pour l’opération, modifié pour être manipulable par le ROV (suppression de la flottabilité et montage d’une poignée adaptée), et pour être connecté au nœud SEAMON Ouest (l’enregistrement autonome des données sera conservé, un second processeur de type Persistor prendra en charge l’interface avec SEAMON). 2-3-4 Géodésie : La jauge de pression JPP2 est opérationnelle sur le site en mode autonome depuis l’été 2006 (campagne GRAVILUCK). En 2008 l’instrument a été remplacé dans un conditionnement différent, mais la jauge reste similaire à celle utilisée pendant la démonstration ASSEM dans le Golfe de Corinthe. Nous disposons donc de la technologie pour la connecter au nœud SEAMON. Le capteur autonome sera récupéré, et un capteur modifié sera déployé puis connecté. 2-3-5 Procédure de récupération des nœuds MOMAR-D - Deliverable D1 80 MOMARDemonstration Demonstration mission MOMAR mission 81 81 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD En cas de dysfonctionnement constaté lors des premiers tests sur les nœuds, ceux ci pourront être récupérés assez rapidement en utilisant la navette ascenseur NASA. Celle-ci a une capacité d’emport de 170 kg dans l’eau, suffisante pour remonter un nœud SEAMON. 2-4 Acquisition de données sur sites 2-4-1 Ecologie : L’objectif principal du nœud « écologie » est la surveillance d’un assemblage dominé par la modiole B. azoricus. Afin de compléter et de valider l’approche temporelle, nous poursuivrons la caractérisation à petite échelle des différents assemblages colonisant l’édifice Tour Eiffel. Ceci permettra de multiplier le nombre d’unités d’échantillonnage et donc, d’élargir l’échelle spatiale de notre étude ainsi que d’obtenir des données à des intervalles annuels. La stratégie, utilisée lors de la campagne MoMARETO, repose sur la mise en place d’une série de sondes de température autonomes sur différents assemblages. En 2010, 12 unités d’échantillonnage seront ainsi caractérisées (chimie, physique, biologie « imagerie ») et instrumentées par 24 sondes de température autonomes (poursuite du plan d’échantillonnage amorcé au cours des campagnes Exomar et Momareto). En 2011, ces unités seront de nouveau caractérisées (chimie, physique, imagerie) et la faune prélevée de façon quantitative. Idéalement, cette étude de dynamique temporelle des assemblages sur la zone Lucky Strike sera poursuivie pendant plusieurs années et appliquée à d’autres structures géologiques (extension de l’échelle spatiale). L’environnement physico-chimique sera caractérisé par 2 méthodes complémentaires en utilisant une instrumentation spécifique développée durant le projet EXOCET/D (Sarradin et al IR News 2007). L’analyseur in situ CHEMINI (Vuillemin et al. 2009) permettra de mesurer les concentrations en sulfure total (Sarradin et al., 1999) et FeII (Sarradin et al 2005) à) proximité des organismes. Deux électrodes Unisense, intégrées au circuit, permettront également de mesurer le pH et l’oxygène. Le préleveur d’eau PEPITO permettra de prélever des échantillons pour compléter la caractérisation du milieu (métaux [Riso et al, 1997, Sarradin et al. 2009] et matière organique dissous et particulaires, radioéléments, méthane). Le capteur de débit sera déployé pour caractériser la vitesse des émissions sur l’assemblage cible (Sarrazin et al, submitted). L’utilisation d’un second module vidéo miniature en cours de développement permettra l’acquisition de séquences vidéo continues de 2 à 6h (associées à des mesures de température) afin d’évaluer la dynamique temporelle de différents assemblages et leur variabilité haute fréquence. L’aspect long terme sera pris en compte par le module vidéo connecté à SEAMON (3 min de vidéo par jour durant 12 mois). Le prélèvement “quantitatif” de faune, associant prélèvement à la pince et à l’aspirateur à faune sur des surfaces définies, permettra de valider les données acquises par les methodes d’imagerie. Un système de prélèvement quantitatif sur substrat dur est en cours d’étude à Ifremer. Les données obtenues seront traitées par des analyses statistiques multivariées, en collaboration avec Pierre Legendre (Université de Montréal). Ce plan d’échantillonnage sera mis en œuvre sur d’autres assemblages chimiosynthétiques profonds, que ce soit en zone hydrothermale (campagne BIG) ou en zone de fluides froids (campagnes MEDECO et WACS). 2-4-2 Chimie des fluides. L’échantillonnage des fluides chauds sera réalisé sur la dizaine de sites équipés de capteurs de température autonomes dans le cadre du thème 1 (Sismicité et dynamique du système hydrothermal ; cf Document 1). On prélèvera également des fluides diffus sur le site « écologie » L’échantillonnage sera conduit en utilisant les seringues titane et le PEP de Victor (et ou PEPITO). Les échantillons seront analysés à bord (alcalinité, pH, oxygène, sulfure et CH4) ou acidifiés et stockés dans des flacons LDPE pour analyses à terre. La composition chimique des fluides prélevés (fluides diffus et fluides haute température) sera déterminée : éléments majeurs et traces, compositions isotopiques (isotopes stables et radiogéniques). Cette opération sera répétée en 2011. 2-5- Déploiement des capteurs autonomes Des sondes de température autonomes seront mises en place dans les sorties de fluides d’une dizaine de sites répartis sur le champ hydrothermal de Lucky Strike. Ce dispositif reproduira celui de la campagne BATHYLUCK 2009. Des modules dédiés à l’étude de la colonisation par les microorganismes seront installés à proximité immédiate des deux sites SEAMON. Ces modules sont constitués de plusieurs tubes avec des substrats minéraux ou organiques différents. L’utilisation d’un système de mesure de la température par fibre optique (Fiber Bragg grating) sera testée durant la campagne sur une zone d’émissions diffuses proche du site de Tour Eiffel. 2-6- Travaux de surface Les périodes de reconditionnement de Victor (8 heures entre chaque plongée) seront mises à profit pour effectuer les récupérations et mouillages (Nœuds SEAMON, bouées BOREL, Piège à particules, OBSs) mais également pour effectuer des profils CTD / Rosette et de microprofileur VPM6000 au dessus du volcan de Lucky Strike, afin de mieux contraindre la structure de la colonne d’eau au cours de la campagne. Le réseau de surveillance sismique local constitué de 4 OBS du réseau national INSU et de 5 OBSs portuguais, sera déployé sur les flancs du volcan de Lucky Strike selon la configuration la plus adaptée (cf légende de la Figure en fin de document 2). MOMAR-D - Deliverable D1 81 MOMARDemonstration Demonstration mission MOMAR mission 82 82 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD Par ailleurs, on installera en surface, sur la bouée BOREL, un GPS permettant de suivre les variations de hauteur d’eau. Ces variations serviront à extraire le signal géodésique des données du capteur de pression. Le signal de ce GPS sera analysé en utilisant un GPS de référence à terre, installé à Faial et maintenu pendant toute la durée de l’expérience (1 an) par nos collaborateurs de l’Université de Lisbonne. Enfin, le câble de la bouée BOREL sera équipé de 10 à 15 capteurs de température (ou T-P) autonomes, capables d’un enregistrement par minute pendant 1 an. Ces capteurs permettront de suivre l’évolution de la colonne d’eau, avec des objectifs d’océanographie physique (ondes internes). L’intégration de ces données de température avec les données GPS sur la hauteur de la colonne d’eau permettra aussi d’interpréter les données du capteur de pression en termes de déplacements du sol. 2-8 Calendrier prévisionnel de la campagne 2010 L’organisation de la campagne prendra en compte l’expérience acquise durant la campagne Medeco avec notamment l’utilisation de plusieurs ascenseurs au cours d’une même plongée. Ceci nous permettra de programmer des plongées d’une durée moyenne supérieure à 24h. Le programme ci-dessous prévoit une durée uniforme de 24h et est indicatif. Il sera affiné au cours du projet puis validé avec Genavir pour tenir compte des contraintes opérationnelles. Nous avons inséré une marge pour nous permettre de récupérer et remouiller des instruments défaillants. En cas de bon fonctionnement, ce temps de travail pourra être utilisé pour des prélèvements et mesures complémentaires (fluides, écologie) et pour des prélèvements de modioles sur le site Menez Gwen pour le projet BioBaz. Ce projet a pour objectif la compréhension des relations de Bathymodiolus avec ses symbiontes et son environnement dans trois champs hydrothermaux du chantier MoMAR (Menez Gwen, Lucky Strike et Rainbow). Une demande de campagne BIOBAZ est soumise par F . Lallier pour 2011. Pendant MoMARSAT, les échantillons de modioles pourront être récupérés par J. Sarrazin, A. Colaço et P.M. Sarradin, également impliqués dans BioBaz.

Cependant, dans la mesure où l’objectif de MoMARSAT est de pérenniser l’instrumentation du site, cette stratégie sera adaptée en fonction des perspectives offertes en ce sens d’ici 2011 (maintenance de certains équipements au lieu de leur récupération). En 2011, il est prévu de récupérer tous les capteurs de T° C autonomes déployés sur 5 sites du champ hydrothermal (Nuno, SEAMON Ouest, Tour Eiffel-SEAMON Est, Y3, Statue of Liberty ; voir Figure en fin de document 2), et le volet d’acquisition de données sur sites sera complet (écologie, chimie des fluides sur les deux sites SEAMON, et géodésie). Il est également prévu une plongée pour nettoyer le site de tous les déchets qui auraient pu s’accumuler autour des noeuds SEAMON au cours ou avant l’expérience. Le déroulement général sera le suivant : 1. Récupération ou maintenance des instruments connectés. La récupération des Nœuds sera effectuée par Victor en utilisant des mouillages de flottabilité. Victor ira ensuite connecter le mouillage flottabilité et le Nœud avant de larguer le lest de descente. L’étape de récupération a été estimée à 6 jours. 2. Récupération ou maintenance des instruments autonomes et des mouillages. 3. Acquisition de données sur site (écologie, géodésie, chimie) : Pour les volet écologie (5 jours), et chimie (échantillonnage des fluides chauds et des fluides diffus ; 3 jours), la stratégie sera identique à celle de 2010. Pour le volet géodésie, 6 jours sont prévus pour une seconde campagne de mesure du réseau géodésique (10 repères installé et mesuré une première fois en 2006 ; voir carte en fin de Document 2). La mesure du réseau, effectuée avec le “pressionaute” de l’IPGP un outil comprenant plusieurs jauges de pression Paroscientific, suppose des boucles de mesures (voir fiche de valorisation de la campagne GRAVILUCK). 4. Travaux de surface : Les périodes de reconditionnement de Victor (8 heures entre chaque plongée) seront mises à profit pour effectuer des profils CTD / Rosette au dessus du volcan de Lucky Strike, afin de mieux contraindre la structure de la colonne d’eau au cours de la campagne. 5. Une plongée « nettoyage de site » dans le cadre de la gestion de l’aire marine protégée est prévue en 2011. Les lests abandonnés seront localisés sur les mosaiques photo (voir fiche de valorisation de la campage MoMAR2008-Leg1). La procédure de remontée ou déplacement de ces lests est à étudier. Nous ne proposons pas de calendrier précis pour la MoMARSAT 2011. Son déroulement sera en grande partie similaire à celui de la campagne 2010. Les principales modifications seront une durée plus courte des opérations sur l’infrastructure SEAMON, mais l’ajout de 6 jours de mesure du réseau géodésique.

Lisbonne (Rui Manuel Fernandez) sur l’île de Faial pendant la durée de la démonstration (2010-2011). Annexe : Description de certains instruments propres aux équipes demanderesses : The Ocean Bottom motion meter, Univ. Bremen The equipment consists of one instrument, the OBM. The OBM has a weight of about 170kg (in water 60kg). It has a triangular shape with a triangular base plate on three legs. Overall dimensions of the OBM are 1.36 m for the long edge, 0.68 m for the perpendicular bisector of the base plate and 0.96 m for the short edges, with a total height of the instrument of 0.78 m. The OBM must be leveled at the sea floor, so that a ROV is necessary for installation and recovery. The OBM dimensions are such that it can be deployed by the ROVs Quest, KIEL -5 2 6000, Jason 2 and Victor 6000. The OBM has accelerometers with 10 m/s resolution, to record acceleration from DC to 10 Hz in three perpendicular directions. It has a tilt sensor with two perpendicular horizontal axes with 0.1 rad resolution, to record local slow sea floor tilt. An absolute pressure gauge (Paroscientific DigiQuarz) with Bennest technology is integrated in the system and records vertical seafloor displacements with respect to the sea surface with millimeter resolution. Additional thermistors record sensor temperature and sea water temperature, to control environmental conditions for OBM operation. The OBM runs autonomously, but monitoring in real-time through a network are preferred. During the cruise the OBM has to be prepared for deployment, i.e. all components and the batteries have to be checked thoroughly before the OBM will be deployed by an ROV. It will continuously record long-term time series of acceleration, tilt, pressure and temperature until recovery during the second cruise by an ROV. The OBM should be installed next to one of the geodetic benchmarks and the pressure data recorder at the summit of the volcano. We prefer to integrate it in the network depending on the networks capability, but it can also run autonomously. The time series of acceleration, tilt, pressure and temperature will be analyzed for their spectral information and correlated for the interpretion of seafloor deformation processes and magmatic and hydrothermal activity. CTD/ADCP package The equipment consists of a CTD, a profiling Doppler current meter, a central data logger and an energy supply. The instrument package is completely autonomous. It will be programmed for the mission and the data will be read out after retrieval. An autonomous instrument package consisting of a CTD sensor, an ADCP and a data logger together with the necessary energy supply will be deployed. A location close to a hydrothermal vent has to be selected preferably where fluid samples are taken as well. The data set collected will consist of the following parameters – temperature, pressure, salinity and current speeds. Theses data will be sampled at a repetition rate of 0.25 Hz continuously with a total time endurance of 3 months. If possible the system should be deployed at least for these three months. No specific preparatory work on board or on shore is needed. The system can be deployed by the elevator of IFREMER and then be positioned by the ROV VICTOR. After retrieving the raw data from the sensor systems some post processing has to be done to achieve time synchronisation and filter out outliers. To be able to interpret the data adequately it is also necessary to know precisely about the topography around the measurement location and to have knowledge about tide cycles. A basic model is currently developed at the University of Bremen but it will be essential to discuss and evaluate the data with a colleague from Lamont Doherty Laboratories, Andreas Thurnherr, who is an expert in this field. He already indicated his interest in participating in the data evaluation. Temperature sensors The sensors are autonomous and can record T at a rate of <5 min over >1 years. They are available for measurement of high-T (>400°C) and low-T (<100°C) fluids. Data wil be processed upon the recovery of the instruments in 2011, to study temporal variability (tidal forcing, random T variations, seasonal/current-induced changes), spatial correlation of these variations among different sites, and their correlation with seismicity. NOC chemical and temperature sensors NOC though NERC funded programmes has been involved in the development of sensors for the determination of dissolved reduced species of manganese and iron. Early work demonstrated the use of the Mn sensor on Autonomous Underwater Vehicles (AUV’S) in shallow coastal systems (Statham et al., 2003, 2005). This technology was developed further and recently the sensors developed at NOC for the determination of Fe and Mn species, in collaboration with the WHOI deep submergence group, and had success in the pin-pointing of hydrothermal vent sites using AUV’s (German et al., 2006). The use of a Fiber Bragg grating allows the multi-point temperature sensing with a high level of accuracy and sensitivity. It is envisaged that a number of sensing nodes will be deployed around the selected vent sites. We are in the MOMAR-D - Deliverable D1 89 MOMARDemonstration Demonstration mission MOMAR mission 90 90 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD process of developing and in-situ methane sensor as part of the MOMARnet project, this is showing great promise and we will have a fully deployable prototype of the system for the cruise in 2010. We will require time to integrate our sensors onto the system to be deployed during the cruise, this will occur ideally before the cruise. We envisage that the system for dissolved iron and manganese will have a functioning life on the order of 2 months. The temperature sensor and the methane sensor will be operable for the entire length of the deployment. We will require a minimum of 3 people on each cruise. This will allow the deployment of the systems, and, we will work in association with Valerie Chavagnac to collect fluid samples for the chemical characterisation of the environment at the time of deployment and recovery. TEMPO TEMPO [Sarrazin et al. 2007] is a long-term imaging module equipped with a deep-sea video camera and two LED lights. An efficient biofouling protection is installed on the camera port hole and on the lights. A CHEMINI Fe in situ analyzer and 3 temperature probes are coupled to the TEMPO module to monitor environmental changes in parallel to community dynamics. The whole system is powered by a SEAMON node [Blandin et al. 2005]. TEMPO was tested and deployed during the Momareto cruise and was set to acquire time series (video images, temperature and Fe concentrations) during 3 months on the bottom. Due to technical difficulties, it has not been possible to recover TEMPO in 2007, but data is stored in the instrument, and recovery is planned for the summer of 2008. A second generation of in situ chemical analyzer (CHEMINI, Vuillemin et al. in press) based on flow analysis and colorimetric detection was used for the analysis of total sulfide and iron II or total iron (II + III, Sarradin et al. 2005). Sampling followed by on board analysis remains often the only analytical way to complement the range of geochemical species covered by in situ sensor, and to validate data obtained by in situ measurements. Pepito is a small volume water sampler combining high number of samples (up to 25). It has been tested and used for many different purposes: ground truthing of the CH4 sensor, in situ filtration, sampling of water samples in the water surrounding hydrothermal assemblages. The Aanderaa dissolved oxygen (DO) sensor 3830 is a life-time based optical sensor based on dynamic fluorescence quenching (Tendberg et al.) . MOMAR-D - Deliverable D1 90 MOMARDemonstration Demonstration mission MOMAR mission 91 91 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD DOCUMENT N° 4 MoMARSAT ANALYSE ET TRAITEMENT DES ECHANTILLONS ET DES DONNEES L’analyse et le traitement des données concerneront les 5 thèmes définis dans le document 1 : • Thematic Package 1: Seismicity and hydrothermal activity • Thematic Package 2: Vertical deformation of the seafloor at the Lucky Strike volcano • Thematic Package 3: Chemical fluxes at Lucky Strike vents • Thematic Package 4: Ecology at Lucky Strike vents • Thematic Package 5: Physical oceanography Dans les § qui suivent nous ne rentrons pas dans le le détail des traitements prévus : des informations peuvent être trouvés dans le document 1, les références bibliographiques, et les fiches de valorisation des campagnes antérieures. Les données analysées à bord proviendront d’échantillonnage (fluides et biologie), de capteurs manipulés par le ROV, de capteurs autonomes déployés pour de courtes durées (≤ durée campagne), de capteurs autonomes déjà en place avant la campagne, et des capteurs connectés à SEAMON pour lesquels l’ensemble des données n’auront pas été transmises par satellite (ex : sismomètre, caméra vidéo). Vous trouverez un tableau de tous ces instruments dans le document 1 (§ 4). Un tableau spécifique aux instruments connectés à SEAMON se trouve dans le document 2. Le travail à terre concernera d’une part les données en temps semi-réel transmises par l’observatoire, et d’autre part le traitement plus poussé des données acquises pendant les campagnes. L'essentiel de l'exploitation des résultats devra être réalisé dans un délai de 12 à 24 mois après la seconde campagne. L’aspect original par rapport à des campagnes d’instrumentation plus classiques sera le fort poids donné à l’intégration de données de type très différent (ex. données sismique et chimie, température des fluides), et l’ambition des objectifs en termes de gestion et d’archivage des données. La mise au point d’une politique de dissémination des données et d’une stratégie de traitement de ces données multidisciplinaires est un des objectifs du projet MoMAR-Demo (cf plan de travail prévisionnel, Section 6 du Document 1). La liste des participants et leurs principales responsabilités thématiques figurent dans le document 5. 1- Analyses et traitements des échantillons et des données effectués à bord 1-1 Ecology at Lucky Strike vents Echantillons/ données Traitement Imagerie optique Données in situ Calibration laboratoire Calibration in situ Collecte d’échantillons pour comparaison Reconstruction vidéo 3D Prélèvements discrets Particules Echantillons biologiques Construction d’un MNT Acidification, congélation Fixation Tri Dissection Fixation (alcool, formol, azote liquide) Transfert vers LabHorta Fixation (alcool, formol, azote liquide) Echantillons microbiologiques Analyse à bord Logiciel Adélie Analyses automatiques et manuelles Chemini Analyseusr NOC Capteur méthane Capteur débit Température Optode O2 Mesures pH 1-2 Chemical fluxes at Lucky Strike vents Stockage des échantillons, acidification des fluides hydrothermaux chauds, mesures de base (oxygène dissout, alcalinité, H2S). Analyse des teneurs en méthane des fluides diffus prélevés près des capteurs de chimie pour calibration. Egalement analyse des nutriments. 1-3 Seismicity and hydrothermal activity En 2010 récupération d’un an de donnée des OBSs autonomes qui auront été redéployés en 2009 (BATHYLUCK-2009) sur le pourtour du volcan (localisation sur carte document 2). En 2011, récupération d’un an d’enregistrement sur tous les instruments autonomes et connectés (OBSs, dont l’OBS connecté dont on n’aura transmis qu’un subset de données via la liaison SEAMON, et sondes de température), premier traitements et analyse préliminaire des séries temporelles. MOMAR-D - Deliverable D1 91 MOMARDemonstration Demonstration mission MOMAR mission 92 92 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD 1-4 Vertical deformation of the seafloor at the Lucky Strike volcano En 2010, récupération des données des capteurs de pression qui auront été réinstallés en 2009 pendant Bathyluck-2009 (localisation sur carte document 2), récupération des données GPS acquises en cours de campagne puis dépouillement. En 2011, les données d’un des capteur de pression auront été récupérées en temps semi réel, ainsi que celles des deux GPS (bouée Borel et station fixe à Faial). On mènera la seconde campagne de mesures du réseau géodésique (5 ans après la première en 2006) et on intégrera ces données aux données des deux capteurs de pression permanents. 1-5 Physical oceanography Acquisition et traitement des données de CTD, d’ADCP de coque et, en 2011, d’un an d’enregistrement des capteurs de température sur le mouillage de la bouée Borel. 2- Analyses et traitements des données en temps semi-réel transmises par l’observatoire Les modalités de ce traitement feront l’objet d’un groupe de travail mis en place dès le printemps 2009 par le projet MoMAR-Demo. En tout état de cause, ce traitement se fera en étroite collaboration entre les 4 thèmes qui bénéficieront de données transmises par SEAMON et acquises par les capteurs autonomes, afin de coupler, les données de température, de chimie des fluides, de sismicité, et de déformation verticale du sol. Un des objectifs du travail préliminaire au cours de l’année 2009-2010 sera de préparer la détection d’évènements dans une optique de « réponse rapide » et de faire l’interface avec les ingénieurs qui mèneront l’adaptation des instruments au système SEAMON. Par exemple modifier le rythme d’échantillonnage de certains capteurs, éventuellement organiser une intervention sur zone avec l’Archipelago (par exemple faire des prélèvements d’eau pour détecter un panache après une éruption). 2-1 Ecology at Lucky Strike vents Analyse régulière des données transmises par SEAMON, suivi des enregistrements des capteurs environementaux. 2-2 Chemical fluxes at Lucky Strike vents Analyse régulière des données transmises par les capteurs de chimie. 2-3 Seismicity and hydrothermal activity Analyse régulière des données transmises par l’OBS. 2-4 Vertical deformation of the seafloor at the Lucky Strike volcano Analyse régulière des données transmises par le capteur de pression et par les 2 GPS (bouée Borel et station fixe à Faial). 3- Analyses et traitements à terre des données acquises pendant les campagnes Pour l’interprétation, il sera primordial de maintenir une communication étroite entre les groupes des différents thèmes. En effet, l’essentiel du bénéfice scientifique viendra de la confrontation des données des différents capteurs. Plusieurs réunions sont prévues dans le cadre du projet MoMAR-Demo. Une réunion générale sera organisée en fin 2011 afin de finaliser le traitement des données temporelles acquises par les différentes équipes. 3-1 Ecology at Lucky Strike vents Echantillons Traitement/stockage Analyse Imagerie optique DVD Plaquage sur MNT Mise à l’échelle Traitements manuels et automatiques en cours de développement PSA, ICP-MS, HSS-GC, MEB, CI Prélèvements discrets (eau / Acidification particules) Congélation Données courants Echantillons biologiques Fixation Congélation Traitement -Composition, densité, biomasse - Calorimétrie, isotope stables - Echantillonnage pour ADN et ARN 3-2 Chemical fluxes at Lucky Strike vents Analyse géochimique plus poussée (incluant rapports isotopiques stables et radiogéniques pour les fluides hydrothermaux chauds). Dépouillement des séries temporelles des capteurs chimiques. Interprétation. 3-3 Seismicity and hydrothermal activity Dépouillement des enregistrements sismiques complets, identification des évènements, caractérisation des profondeurs hypocentrales (en utilisant les modèles de vitesse établis pour le substratum du volcan pendant la campagne SISMOMAR ; Seher et al., 2006).

Analyse des séries temporelles, intégration des données des 2 campagnes de mesure du réseau géodésique, lien avec la sismicité et les variations de température et de chimie des fluides, interprétation. 3-5 Physical oceanography Synthèse d’un an d’enregistrement de la chaîne de thermistances autonomes, étude de la dynamique de la colonne d’eau, ondes de volume. 4- Archivage Les opérations effectuées pendant la campagne seront archivées via le logiciel embarqué Alamer. Les échantillons et données seront ensuite référencés dans la base de données BIOCEAN et associés à leur détenteur. Cette base sera consultable par les participants à la campagne. Les rapports de plongées et les données acquises par le submersible seront accessibles après la mission sous forme de CD-ROM. Les données vidéoscopiques brutes seront à la disposition des participants de la campagne après engagement de confidentialité vis-à-vis des médias. L’archivage, et le contrôle des données issues des campagnes et délivrées par l’observatoire seront pris en compte par le département IDM Ifremer sur une base existante. Les modalités de cette prise en compte seront définies en début de projet par les participants, en accord avec les standards ESONET et internationaux. Les principes de la mise à disposition des données pendant la durée du projet seront approuvés par chaque participant et répondront également aux spécifications qui seront définies dans le cadre du NoE ESONET. En fin de projet, ces données seront accessibles via la base de données ESONET.

Les participants à terre ou en mer du projet, qui viennent de France, d’Allemagne, du Portugal et du Royaume Uni. Nous avons aussi, via les « Work Packages » d’ESONET, des collaborations prévues avec un plus grand nombre d’instituts européens et extra-européens. Par exemple, tout ce qui concerne le « Data management » sera mis au point en lien avec le WP correspondant d’ESONET, et nous avons déjà des interactions avec plusieurs partenaires non participants à MoMARSAT, pour le développement des communications acoustiques en particulier. Une mention spéciale va à Neptune Canada avec qui nous aurons des liens importants, via le MoU qui lie l’Ifremer et l’Université de Victoria. Nous avons aussi des collaborations prévues avec les partenaires du futur réseau Marie Curie SENSEnet pour le développement de capteurs biogéochimiques adaptés aux environnements hydrothermaux sous-marins. Au sein du projet MoMAR, la demande MoMARSAT aura des liens avec la demande Hydro-MoMAR ou MARCHE 3 soumise par J. Perrot et J. Goslin pour la maintenance du réseau régional d’hydrophones. Nous aurons aussi des collaborations avec l’équipe du projet BioBaz (F. Lallier et al.), si celui si est retenu. Enfin, les aspects écologie du projet MoMARSAT recoupent certains objectifs du projet HERMIONE (suite au projet HERMES ; appel d’offre FP7 call ENV.2008.2.2.1.2. Deep-Sea ecosystems). Les participants impliqués viennent d’Ifremer, IMAR et NOC. HERMIONE, coordonné par P. Weaver du NOCS, est en cours de signature. MOMAR-D - Deliverable D1 99 MOMARDemonstration Demonstration mission MOMAR mission 100 100 PROPOSITION DE CAMPAGNE A LA MER IFREMER - IPEV – IRD DOCUMENT N°6 MoMARSAT ASPECTS INTERNATIONAUX ET ENGAGEMENTS CONTRACTUELS Contacts préliminaires éventuellement pris et interlocuteurs privilégiés des pays riverains La zone de travail (Lucky Strike), est située dans la ZEE portugaise. L’équipe portugaise l’Universidade do Azores (IMAR), à Horta fait partie intégrante du projet ESONET et embarque 2 scientifiques. L’équipe de l’Université de Lisbonne est responsable d’une partie de l’instrumentation sismique et embarque 2personnes. Enfin, le centre de Volcanologie et d’Evaluation des Risques Géologiques de l’Université des Açores embarquera une personne sur la campagne 2011. Personnel étranger invité, engagements contractuels dans le cadre de programmes européens Ce projet s’inscrit dans le cadre de l’appel d’offres « Demonstrations missions » du Réseau d’excellence ESONET. Dans ce cadre, ESONET nous permettra de financer du temps personnel et des frais de fonctionnement. Ce projet d’observatoire regroupe des participants de l’Université de Brême, et du centre MARUM en Allemagne, des Universités de Lisbonne et des Açores au Portugal, et du NOC (Southampton) an GrandeBretagne, tous partenaires du NoE ESONET. Manifestations éventuelles post-campagnes (colloques, conférences, échanges de personnel) Le projet de démonstration MoMAR-Demo, retenu par ESONET, comprend plusieurs réunions pre et post campagnes. Par ailleurs, ce projet sera intégré au travail des différents Work Packages d’ESONET. Il sera donc discuté dans le cadre plus général des réunions ESONET et bénéficiera des possibilités offertes par ESONET pour l’échange de personels. Le projet « Grand public » de MoMAR-Demo reprendra les bases du projet mis en place durant MoMARETO (Sarrazin et al. 2007) et permettra la dissémination de nos résultats vers le grand public à travers des conférences, site web, publications et surtout expositions dans le réseau d’aquarium européen. Une retransmission de plongée en direct est également envisagée. NEPTUNE Canada Les résultats obtenus dans le cadre de MoMAR-D pourront être comparés à ceux obtenus par l’observatoire câblé NEPTUNE Canada. Cette comparaison pourra se faire aussi bien du point de vue technologique (câblé vs non câblé, antifouling, boîtes de jonction, connecteurs utilisés, …) que scientifique. Ainsi, un module TEMPO doit être connecté au printemps 2009 sur le site hydrothermal Endeavour (Juan de Fuca). Cette collaboration s’effectue dans le cadre d’un Memorandum of Understanding signé entre Ifremer et l’Université de Victoria.

Jérôme Blandin, Instrument Systems Project Manager, Ifremer, TSI, BP70 29280 Plouzané, France, [email protected] Professional Career After graduating in 1987 with a diploma of Electrical Engineering from the Institut National des Sciences Appliquées de Lyon (France), Jérôme Blandin worked for two years in the railway industry as a Test Engineer for the Franco-British train manufacturer GEC-ALSTHOM. He tested and fine-tuned the motor-blocks of the future Eurostar high-speed train, in Preston (UK). He then joined an 18 person company (LIM Geotechnologie) specialized in geotechnical instrumentation, as the technical responsible for the products of soil-injection process control, for four years. His activities included the technological choices (mainly in electronics) for the products range, their development, tests and maintenance and also some sensors enhancement. In December 1994, he joined the Institut Français de Recherche pour l’Exploitation de la Mer (French Research Institute for Exploitation of the Sea, IFREMER), as an electronics development engineer for oceanographic instrumentation. He was involved in numerous projects including the ROV Victor 6000 science module and the design of the electrical / electronic architecture of the deep sea penetrometer Penfeld. He introduced the use of a field bus (Controller Area Network, CAN) as a modular and reliable backbone inside multi-sensor deep-sea platforms. He designed the near-real-time communication system of the deep-sea seismic observatory GEOSTAR. From 2002 to 2004, he directed the EU funded ASSEM project, a research and technological development project of a long term distributed seabed monitoring solution, including a novel modular seabed infrastructure, its real time communication means and the data management system on shore. The project included two years of development as well as technological cruises with a manned submersible for demonstrating the monitoring system at scale one. He is currently responsible for the design of several seabed observatories derived from the ASSEM technology, with applications in slopes stability monitoring, deep sea ecosystems study and shipwrecks pollution monitoring.

Résultats majeurs obtenus : La campagne Momareto s'est déroulée du 7 août au 6 septembre 2006 au large des Açores sur le navire océanographique Pourquoi Pas?. La campagne Momareto a permis l'embarquement de 55 scientifiques, ingénieurs et techniciens de plusieurs nationalités et de quatre journalistes. Deux plongées Victor ont été réalisées avec le nouveau module de mesures en route et 21 plongées ont été faites avec le module de prélèvement de base. Quatre plongées ont été effectuées sur le site Menez Gwen, 3 plongées sur le site Rainbow et 16 plongées sur le site Lucky Strike. Cette campagne, pilotée par l'Ifremer (chefs de mission : PM Sarradin et J Sarrazin, DEEP/LEP) était divisée en deux legs. Le premier leg (7-17 août), financé en partie par l'Europe (étape de démonstration du projet européen EXOCET/D), avait comme objectif principal de valider une quinzaine de prototypes dédiés à l'étude des écosystèmes marins profonds, développés dans du projet EXOCET/D. L'utilisation au cours des deux premières plongées du module de mesure en route de Victor, équipé du sondeur multifaisceaux et d'un sonar pêche a permis i) l'obtention d'une carte micro-bathymétrique de très haute résolution du site hydrothermal Lucky Strike avec un zoom sur l'édifice Tour Eiffel, ii) de valider l'utilité du sondeur pêche (collaboration C. Scalabrin) pour la cartographie à petite échelle des émissions hydrothermales et de iii) vérifier l'interférence soupçonnée entre le SMF et le sonar pêche. Deux caméras de stéréovision (IRIS Ifremer/SM- et CAMEREO -AWI-), permettant la reconstruction 3D de petites structures, ont été testées. L'utilisation du sonar Tritech "Super seeking dual frequency profiler" pour cartographier la distribution de la faune et des substrats sur les édifices hydrothermaux a pu être validée techniquement au cours du premier leg. La partie "imagerie vidéo" (Ifremer/SM) du module d'observation biologique TEMPO a été testée avec succès lors d'un mouillage autonome. L'analyseur chimique miniaturisé CHEMINI (Fer et Sulfure -Ifremer/TSI), le préleveur d'eau PEPITO (Ifremer/TSI) ainsi qu'un capteur de méthane (AWI) et un débitmètre (Cardiff University) ont été testé à plusieurs reprises avec succès dans le milieu hydrothermal. Le déploiement sur plusieurs jours d'une CTD associée à un profileur de courants (Université de Brême) à proximité de l'édifice hydrothermal Tour Eiffel a permis l'acquisition de données de courant à petite échelle autour de la structure. Enfin, les trois outils dédiés au prélèvement et à l'échantillonnage de la faune (enceinte sous pression Periscop -UPMC-, respiromètres sous pression DESEARES -Station biologique de Roscoff- et colonisateur microbien AISICS -Ifremer/TSI) ont été testés avec succès. Mis à part la mise en évidence d’ajustements et d'améliorations possibles sur les instruments testés, ce premier leg a été un grand succès. Il a également montré l'importance de la phase MOMAR-D - Deliverable D1 114 MOMARDemonstration Demonstration mission MOMAR mission 115 115 Fiche de valorisation de campagne MoMARETO 2006 de test/validation technologique, initiée à Toulon en avril 2006, avant le passage à l’utilisation scientifique. Le site web de la campagne Momareto a été lancé, avec l'aide d'un webmaster terrestre, au cours de ce premier leg. Le deuxième leg (18 août – 5 septembre) avait pour objectifs principaux de i) rechercher les liens entre la distribution spatio-temporelle des assemblages de moules et les facteurs environnementaux sur le champ hydrothermal Lucky Strike, ii) d'étudier la réponse et l’adaptation des organismes hydrothermaux aux caractéristiques et aux variations à court terme des facteurs du milieu et iii) de communiquer les avancées de cette campagne en temps réel avec le grand public. Une partie de l'instrumentation testée au 1er leg a été utilisée avec succès pour l'échantillonnage et l'étude de la faune ainsi que pour la caractérisation du milieu. Les différentes équipes scientifiques impliquées ont pu mener à bien leurs expériences et les objectifs globaux sont atteints. Le module d'observation biologique à long terme TEMPO a été déployé avec succès en fin de campagne sur un assemblage de moules. Il permettra le suivi de la dynamique de cette faune et de son habitat pendant un an. Tempo constitue la première phase dans l'établissement d'un observatoire sur le champ hydrothermal Lucky Strike dans le cadre du projet MoMAR. Des sondes de température et des modules de colonisation ont également été déployés pour compléter le suivi temporel. Au niveau communication, la campagne affiche un réel succès avec plus de 18 articles dans la presse, 6 émissions radio et au moins trois émissions TV. Le site web a connu la deuxième plus grande affluence des sites Ifremer avec 10% du trafic. Il a attiré au moins 10 000 internautes distincts (hors Ifremer) et a permis une réelle synergie avec les gens du bord. Enfin, une grande première avec la "Nuit des abysses", une plongée en direct, rediffusée au centre Ifremer de Brest devant 250 personnes. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Publications d’articles originaux dans des revues avec comité de lecture référencées SCI Publications dans d’autres revues scientifiques Publications sous forme de rapports techniques Articles dans des revues / journaux grand public Publications de résumés de colloques Communications dans des colloques internationaux Communications dans des colloques nationaux Rapports de contrats (CEE, FAO, Convention, Collectivités …) Applications (essais thérapeutiques ou cliniques, AMM …) Brevets – enveloppes Soleau Publications d’atlas (cartes, photos) Documents vidéo-films Publications électroniques sur le réseau Internet Etudiants ayant utilisés les données de la campagne Thèses et post doc ayant utilisés les données de la campagne Validation des données Transmission au SISMER Transmission à d’autres banques de données Biocean Transmission à d’autres équipes Considérez-vous l’exploitation MOMAR-D - Deliverable D1 Nombre 10 4 soumises 2 2 22 9 22 16 4 2 2 2 7 6+2 En cours Oui : ....

Validation des données : La campagne a permis d’acquérir des données de magnétisme, de gravimétrie, de bathymétrie et de réflectivité. Toutes ces données ont été validées (élimination des points aberrants) à bord. Par l’équipe SIMRAD et par l’équipe scientifique (pour mag et gravi). Ces données ont été transmises au SISMER sous format ngdc, .mul, .nav et .imo. EXPLOITATION en cours DES DONNEES : L’exploitation de base de la campagne est terminée depuis 3 ans. Les résultats, et surtout l’intérèt renouvellé pour la zone d’étude, qui comprend les sites hydrothermaux du projet MOMAR, justifient la poursuite d’un travail au delà de cette exploitation de base. Deux articles utilisant des données de la campagne SudAçores sont en préparation , l’un sur le contexte tectonique et gravimétrique du chantier MOMAR, l’autre sur la structure sismique des zones à croûte épaissie (plateaux volcaniques), à partir des données de sismique légère.

Ultraslow-spreading ridges are known to expose large expanses of mantle-derived peridotites in the seafloor, and could offer similarities, in terms of magmatic and tectonic processes, with the early stages of oceanization at so-called “non-volcanic” rifted margins. Our study focuses on the most melt-poor (seismic crustal thickness about 3.5 km ; Muller et al., 1999) portion of the SWIR, near the Rodriguez triple junction. We report on a large set of new off-axis data, covering about twice the area of Iceland, and extending to maximum crustal ages about 28 myrs. This is the first extensive off-axis data set for a melt-poor ultra-slow spreading ridge. It is therefore the first opportunity to study the temporal evolution of spreading processes in this environnement. Due to very low sedimentation rates, details of basement morphology are apparent even in the oldest parts of our study area. We have been able to identify 3 types of seafloor, two of which show no evidence for a volcanic upper crustal layer. The following paragraphs give a brief description of these two types of a-volcanic seafloor. In our talk, we will adress two principal questions : 1- how do these a-volcanic terranes form, and 2- are they truly amagmatic regions of the axis ? One type of a-volcanic seafloor present in our study area has been described previously as « corrugated surfaces » in many other regions of slow to intermediate spreading oceans. Corrugated surfaces in our study area are remarkably abundant: we counted 39 such surfaces, about as many as have been identified to date throughout the World’s oceans. These 39 corrugated surfaces range in dimensions from 4 to 73 km in the along-axis direction (i.e. along-axis extension of inferred large offset normal fault at the time of their formation), and from 4 to 30 km in the spreading direction (i.e. cumulated offset along these faults over their period of activity). A few of these surfaces are juxtaposed in a pattern suggesting that they formed as part of a long-lasting episode of large offset axial normal faulting. The most spectacular of such episodes appears to have affected a ridge length of more than 100 km, and to have lasted 6 myrs. The other type of a-volcanic seafloor identified in our study area has no previously described equivalent, although it does correspond to the off-axis expression of the so-called « amagmatic ridge segments » that have been described at the SWIR and Gakkel ultra-slow ridges (Dick et al., 2003; Michael et al., 2003; Sauter et al., 2004). It occurs in the form of broad, spreading-perpendicular or oblique ridges, with a smooth, locally rounded topography. We called this type « smooth a- MOMAR-D - Deliverable D1 126 MOMARDemonstration Demonstration mission MOMAR mission 127 127 volcanic seafloor ». It lacks volcanic features and exposes ultramafics even when on axis. This is very different from observations made at the Mid-Atlantic Ridge where basalts are always present on axis, but where peridotites or gabbros are locally exposed on rift valley walls. Smooth a-volcanic seafloor represents about 40% of our mapped area, and appears to have been emplaced simulataneously on both flanks of the ridge, in marked contrast with corrugated surfaces.

SISMOMAR was a seismic reflection and refraction study of crustal structure beneath the Lucky Strike segment of the Mid-Atlantic ridge. The experiment was composed of a 4x18 km 3D multichannel seismic reflection experiment over the top of the Lucky Strike volcano, a 20x20 km 3D seismic tomography experiment covering the volcano and surrounding axial valley and two long seismic tomography and reflection lines along and across the rise axis (Figure 1). We also collected bathymetric, magnetic and gravimetric data The reflection data was collected using a 4.5 km long streamer towed behind the boat and the refraction data was recorded using 25 ocean bottom seismometers (OBS) deployed at 42 sites, SISMOMAR is one of the MOMAR-D - Deliverable D1 Figure 1: SISMOMAR experiment. Map colors indicate depth: purple is ~4 km and red ~1 km. The map is about 120 km wide The 3D reflection experiment lines were tightly spaced within the yellow box, the 3D refraction experiment shots are indicated by the black lines and the 2D refraction lines are shown by the red lines. Blue circles show OBS deployments. 129 MOMARDemonstration Demonstration mission MOMAR mission 130 130 Valorisation des campagnes à la mer Navires Ifremer - IRD - IPEV largest seismic experiments on the Mid-Atlantic Ridge to date: only the "MARBE" experiment is comparable in terms of coverage and number of OBSs (Canales et al., 2000a; Hooft et al., 2000; Magde et al., 2000; Hosford et al., 2001). The OBS positions also provided a good configuration to measure local seismicity and we deployee 2 broadband OBSs to measure the seafloor "compliance" (flexure under ocean waves), which is sensitive to fluid-filled zones within the underlying crust. 3 – Principaux résultats obtenus (avec quelques illustrations) The major results of the experiment include: − The detection of an Axial Magma Chamber reflector beneath the Lucky Strike central volcano, with a major faults penetrating near to its eastern edge [Singh et al., 2006, Nature; Combier, 2007]. − A crustal-scale velocity model that reveals a low velocity zone with a very interesting shape beneath the AMC reflector [Seher, 2008]. − Constraints on layer 2A thickness and velocities. Notably, the nature of the upper crust changes radically across the axial valley bounding walls, whereas it is quite constant along the rise axis. − Detection of several dozen earthquakes during the time that the airguns were not shooting, including 3 earthquakes in 6 days that were very close to the axial magma chamber region.

Il s’agit d’un chantier pluri-disciplinaire ; la campagne Graviluck a permis d’acquérir des données dans plusieurs domaines allant de la géophysique, la géologie, l’océanographie physique à la microbiologie. L’objectif principal de la campagne était géodésique. Lors de la campagne Graviluck, nous avons, pour la première fois sur une dorsale lente, initié une expérience visant à mesurer les mouvements verticaux liés à l’activité magmatique et tectonique qui affectent le volcan central de Lucky Strike et le mur Est de la vallée axiale. Pour cela, nous avons installé deux stations d’enregistrement en continu de la pression en fond de mer et installé/ mesuré un réseau de repères géodésiques au fond. En tout, 12 repères ont été installés et 9 d’entre eux ont été mesurés. La précision obtenue sur les différences de pression (donc de hauteur) entre deux repères géodésiques est de l’ordre du centimètre. Lors des plongées du Nautile, nous avons également acquis des données de magnétisme et de gravimétrie fond de mer qui devraient nous aider à mieux contraindre la structure de la croûte océanique. Réseau géodésique : Les traits et nombres colorés indiquent le trajet effectué durant les différentes plongées de mesure du réseau. Le nombre inscrit en petit dans les sphères orange correspond au nombre de mesures sur le repère.

Parallèlement au programme de recherche principal axé sur la géophysique et mené avec le submersible Nautile, un programme d’océanographie physique et de géologie ont été menés principalement de nuit, depuis la surface. Les données d’océanographie acquises montrent que les hauts topographiques connectant les nombreux bassins à l’axe de la dorsale et dans les canyons sur des flancs de la dorsale sont des lieux permettant des échanges turbulents très energétiques. Cela montre que la topographie des fonds sous-marins joue un rôle important dans la circulation océanique globale et apporte une partie de l’énergie nécessaire à la remontée des eaux profondes vers la surface par mélange turbulent Des données géologiques photographiques de grande qualité ainsi que des échantillons de roche ont été acquises principalement avec une caméra tractée (Towcam). Ces données ont permis entre autres de définir la zone où l’activité volcanique est la plus récente.

La couverture et résolution de ce réseau sont, pourtant, limitées par la distribution inégale des stations. En effet, presque toutes les stations sont à terre, laissant des grands trous dans les données dans plusieurs endroits océaniques. Des stations fond de mer ont été tentes, avec des instruments bien installés (enterrés) pour minimiser le bruit et connecté à terre par un câble sous-marin. Ces installations sont, pourtant, très chères et ont toujours des problèmes techniques assez importants. Par exemple, la station H2O, la plus célèbre et le mieux installé des stations sous-marines, installé en octobre 1999 sur un câble sous-marin entre Hawaii et Californie, n'a fonctionné que trois ans et demi avant de se casser. La réparation, coûtant plusieurs millions de dollars américains, n'a pas encore été financée. Nous avons proposé de faire des déploiements beaucoup plus légers des capteurs sismologiques et magnétiques larges bandes. La partie sismologique, qui consiste en trois déploiements consécutifs d'un an d'un sismomètre large bande, pour une période totale de trois ans, entre été 2007 et été 2010, s'inscrit dans le cadre du projet Européen NERIES. Le lieu choisi est le volcan de Lucky Strike, sur la dorsale Medio Atlantique juste au sud des îles Acores. Le choix du site permet à ces instruments de compléter des données acquis a ce site dans le cadre du programme MoMAR, qui coordonne des études multidisciplinaires (géophysique, biologie, océanographique, chimique, etc) pour étudier la dorsale Medio Atlantique près des Acores, et dont le volcan Lucky Strike est un site clé. 2 – Rappel des objectifs L'objectif principal de l'expérience est d'acquérir des donnes larges bandes sismologiques pendant 3 ans, de les rendre disponible a la communauté scientifique Européen, et étudier le niveau du bruit et de signal sur ces stations. D'autres objectifs ont été de: − Acquérir des données larges bandes magnétiques pour évaluer leur utilité dans un réseau global. − Utiliser les données sismologiques et magnétiques pour contraindre la structure du manteau sous le site Lucky Strike (une zone avec une alimentation magmatique a long terme). − Étudier l'amplitude et variabilité des ondes infragravimetrique de la surface des océans au-dessus de le site − Évaluer si la méthode de tomographie par bruit ambiant a basses fréquences pourrait être utilisé dans les océans. Dans la première année, nous avons déployé une deuxième sismomètre fond de mer entre le site Lucky Strike et une sismomètre large bande sur l'île de Sao Miguel, Acores. Nous avons aussi déployé des courantomètres à cote des sismomètres: un courantomètre doppler qui échantillonnait une fois/seconde pendant 4 jours et un courantomètre mécanique qui enregistrait tous les 30 seconds pendant 8 mois. Lors des missions BBMOMAR, nous avons aussi déployé 4 sismomètres courts-periods pour une étude de sismicité du volcan Lucky Strike. Ces déploiements faisaient partie d'une autre expérience du programme MoMAR (MoMARDREAM et BathyLuck, chef de projet Javier Escartin), mais c'était plus efficace de profiter des ingénieurs OBS déjà à bord pour notre expérience. Aussi nous avons pu profiter de notre sismomètre large bande servait pour en faire la 5e sismomètre de ce réseau. 3 – Principaux résultats obtenus (avec quelques illustrations) Nous avons récupéré les sismomètres en 2008 après un an de déploiement. Tous ont marché et ont enregistré le bruit du fond locale ainsi que les tremblements de terre locaux et distants. Nous ne sommes pas encore au point de fournir des illustrations des résultats.

Hydrothermal systems are responsible for a sizeable portion of the heat loss of the Earth, and are involved in important material and chemical exchanges between the deep earth and the surface. We focus our research on the Lucky Strke hydrothermal vent field, one of the biggest systems found to date and located along the slow-spreading midatlantic ridge. Here numerous vents are spread over an area of 1 km x 1 km, and include both high-temperature vents and zones of diffuse flow. We have initiated the instrumentation on the site to recover coincidental and complete time series, including pressure (tides), seismicity, temperature of fluids, and current meters. This effort is combine with hig-resolution mapping of the area and photo surveys to identify past and future changes in the distribution of hydrothermal outflows. This instrumental and monitoring effor is complemented with numerical modeling. All research is coordinated within the MoMAR program. 2 – Rappel des objectifs The main goal is to obtain coincidental data from pressure gauges, seismometers, température sensors, and current meters. This is complemented by high-resolution geophysical mapping (near-bottom multibeam bathymetry), imagery (electronic still imagery and video), and sampling for geological, geochemical, and geomicrobiological studies of the Lucky Strike site. Monitoring was initiated in 2007 with the installation of seismometer, and continued in 2008 with the installation of both seismometers and pressure gauges. Technical problems prevented the deployment of temperaure sensors at the time. The full implementation of the project is thus planned for 2009, with recovery of instrumentation and data in 2010. 3 – Principaux résultats obtenus (avec quelques illustrations) Instrumentation : We will recover the instruments installed in 2008 in the summer of 2009. Coincidental time series of seismicity, pressure, and température (partial deployment) will only be initiated in the Fall of 2009. Mapping : We have created a georeferenced photomosaic of the hydrothermal system from OTUS imagery acquired with VICTOR. This mosaic extends over an area of ~700x700 m and covers the main active vent areas. Image processing and georeferencing has been carried out with techniques developed in collaborations with the University of Girona (see Escartin et al., 2008). Multibeam bathymetry acquired with VICTOR is being processed at the present time, and results available for the 2009 Bathyluck’09 Cruise. Below we present a Small portion of this mosaic, covering an area of 60 m vertically and 45 m horizontally, where the hydrothermal slab (fractured) and several zones of hydrothermal venting are visible, and correspond to areas covered with white bacterial mats. This cruise also included a film crew for a TV documentary.

The unique faunal communities that develop near these vents are sustained by chemosynthetic microorganisms that use the chemicals in the hot fluids as a source of energy. Environmental instability resulting from active mid-ocean ridge processes can create changes in the flux, composition and temperature of emitted hydrothermal fluids and thus influence the structure of hydrothermal communities. The MoMAR-D project was selected by ESONET as a demonstration mission to deploy and manage a multidisciplinary observing system at Lucky Strike during one year. Lucky Strike is a large hydrothermal field located in the center of one of the most volcanically active segment of the MAR. Monitoring this field offers a high probability of capturing evidence for volcanic events, observing interactions between faulting, magmatism and hydrothermal circulations and, evaluating their impacts on the ecosystem. Two Sea Monitoring Nodes (SEAMON, Blandin, J., Rolin, J.F Sea Technology December 2005, Volume 46, No. 12.) will be acoustically linked to a surface buoy that will ensure satellite communication to a land base station. The first node will be dedicated to large scale geophysical studies and the second, to edifice scale studies such as ecology and chemical fluxes. The infrastructure should be deployed in 2010 during the MoMARSAT cruise (see the Cruise proposal, D1). The objective of this deliverable is to describe the observatory infrastructure, the interface specifications and to update the list of sensors to be connected to the SEAMON nodes. The foreseen location of the 2 nodes and the implementation plan are also presented. 2- Description of the operational system The MoMAR-D experimental design combines autonomous instruments which will store data over the duration of the mission (1 year), and instruments that will be connected to shore via the SEAMON system. 2-1 The SEAMON / BOREL technology The SEAMON system includes a set of long-term, non-cabled sub-sea observatory components, initially developed by Ifremer during the EU ASSEM project (2002-2004). These components have since been upgraded and made more reliable. SEAMON is the generic name of the seabed stations serving a local set of sensors, whereas BOREL (Bouée relais) is the surface data transmission relay. The SEAMON stations are rated for 4000 mwd operations. Each node can provide 8 kWh, allowing for the sensors operation and for a daily data transmission of ca. 40 – 400 kbytes. The main components of SEAMON are the following: COSTOF (Communication and Storage Front-end). This electronic unit serves a set of local sensors by providing them with data storage, communication channels and optionally energy. COSTOF communicates with the ROV via CLSI (see below), and the BOREL buoy via acoustic modems. The COSTOF robustness and modularity rely on the use of a low power field bus (CAN) linking a set of simple identical boards, each board devoted to one sensor. The measurement sequencing is left to each sensor. This way, a COSTOF failure does not prevent data acquisition at the sensor level. Conversely, data duplication at the COSTOF level is a safety factor in case of sensor damage. SEAMON can duplicate this data storage for volume < than 2Gbytes per year. CLSI (Contact-Less Serial Interface) is a small device made of two halves, allowing serial communication between two units, without electrical connection. If one half is connected to a ROV, and the other half to the COSTOF, communication can be established between the ROV and any connected sensor. It is very useful just after the ROV has completed a sensor mechanical installation, to check or fine tune its functioning before the ROV leaves the area. MOMAR-D - Deliverable D2 1 151 MOMARDemonstration Demonstration mission MOMAR mission 152 152 D2- Description of the operational system : interface specifications, sensors, location MoMAR-D The BOREL buoy (Fig.1) is the data transmission relay between the SEAMON stations and the Iridium satellite constellation. It is moored within acoustic range of the SEAMON stations and is composed of two identical independent data transmission channels. Channel 2 can be activated from shore in case of a failure of channel 1. Each data transmission channel is powered independently and comprises an acoustic modem, control electronics and an Iridium modem. The communication is bi-directional and BOREL supports three data transmission modes: periodic (typical rate 6 hours), triggered by events detected on the seabed, and triggered from shore. BOREL has now been used for two years in the Mediterranean Sea, where it was moored at 2000 m depth. The Mediterranean mooring will be modified for MoMAR-D to take into account the sea conditions prevailing in the mid-Atlantic. Its position and the local sea/wind state will be monitored throughout the experiment. The robustness of this mooring is clearly one of the technical challenges of the MoMAR-D experiment. Fig.1: The BOREL buoy 2-2 Acoustic data transmission For five years now, successive SEAMON/BOREL systems have been using the same type of acoustic modems. Their reliability has now reached a satisfying level, but their energy requirement per transmitted bit (a key parameter for non-cabled observatories) can probably be significantly lowered. Ifremer is currently working on this issue. This work started in 2007 with a selection of five modems available on the world market. Among the selection criteria, the lowest energy necessary to transmit 1 bit at a given distance was sought. In 2008, three of these five modems were tested at sea, between a sub-sea station at a depth of 2200 m, and the R/V L’Europe. This test demonstrated that the latest modems require at least 15 times less energy to transmit one bit in those conditions, than the ones used on SEAMON until now. Longer term tests of the two best modems are planned in 2009, between the 2200 m-deep subsea station and a relay buoy. The MoMARSAT experiment will directly benefit from these improvements. Only a subset of data will be periodically transmitted to shore via the BOREL buoy. The subsampling step will be designed specifically for each sensor. Simple subsampling operations can be perfomed by SEAMON such as temporal subsampling, simple statistics, thresholding. 2-3 Configuration of the nodes Two SEAMON nodes will be deployed in the Lucky Strike vent field (see location in §5). A Table of the connected sensors, the volume of data transmitted and the energy required for transmission at each node is provides in § 4. A sketch of the observatory configuration is provided Fig. 2. • SEAMON-East will be primarily devoted to thematic experiments 3 (Chemical fluxes), 4 (Ecology) and 5 (Physical oceanography). It will connect a video camera, chemical sensors and the CTD/ADCP package. This node will be moored at the base of the active hydrothermal edifice Tour Eiffel, near the location of the autonomous TEMPO station deployed during the MoMARETO cruise. • SEAMON-West will be primarily devoted to thematic experiments 1 (Seismicity and hydrothermal activity) and 2 (Seafloor deformation). It will connect the pressure probe and one OBS. This second node will be moored in the western part of the lava lake, near the present location of the pressure probe installed since 2006. 2-4 Underwater connection devices To ease the deployment, the OBS will be be connected to SEAMON underwater using a low cost connection device (CdC,) specially developed and validated during the ASSEM project (Fig. 3).

When possible (volume < than 2Gbytes per year ), the data storage will be duplicated by SEAMON. The Ecology package (TEMPO) and the pressure gauge already have tested operational SEAMON connections. Development will be carried out for the connected OBS (IPGP), the NOCS chemical flow analyzer and the CTD/ADCP mooring. Other sensors will be deployed as autonomous instruments, storing data that will be recovered at the end of the 1 year experiment. 2-6 Biofouling Biofouling is a major issue in the vent ecosystem. Biofilms form on every available surfaces and trap the mineral particles emitted by the hot fluids. The method used successfully (Exomar, 2005 and MoMARETO, 2006) for preventing bio-fouling on the lens of the TEMPO video camera and on an Aanderaa oxygen optode relies on localized microchloration. This method does not modify the image, and the concentrations of chemicals released are negligible. 3- Interface specification The “Instrument integration specifications” is detailed in annex 1. 4- The sensors The project relies on the mooring of various sensors to acquire time series related to the seismic activity of the system, the floor deformation, the chemical fluxes, the dynamics of the fauna and the physical oceanography of the area. Part of the sensors will be connected to the SEAMON nodes and will transmit a subset of data to the Borel buoy and the DMAS on shore. The complete data set will be stored in the sensors and in SEAMON when possible (see §2.5). The other sensors will be used in an autonomous mode. The complete set of data will be downloaded at the end of the experiment when the sensors are recovered. All the sensors will be synchronized at the beginning of the experiment. The drift will be measured after the recovery of each sensor against the GPS clock.

The photomosaic of the area obtained by Escartin et al. (2008, Gcubed, V9, N12) will be helpful to find the convenient place. Finally, the ecological node (Seamon East) will be located at the base of the Tour Eiffel active edifice, to continue the study started by the TEMPO module in 2006.
