Möller. Annual Report 2012 Department of Geology 2012 Reserach at the Department is carried out in Lithosphere and Paleobiosphere Sciences (page 14) and Quaternary Sciences (page 21). We have a three year Bachelor program and a two year Master program in addition to a number of evening, summer and net based courses The research education in Geobiosphere Sciences is a joint education with Physical Geography and Ecosystem Analysis. During 2012 there were 5 board meetings. Members of the Board are shown in Table 1. The Department is most research oriented with c. 85% of the turnover related to research Table 1.

These figures have been fairly stable over the many years despite increasing externa grants and resources for basic education. In the financial statement for 2012 (Fig. 1) basic education shows a negative result with 1,4 million SEK as anticipated, whereas faculty funded research for both Quaternary and Lithosphere and Paleobiosphere Sciences shows positive results. For basic education (GU) the agency capital after 2012 has turned negative with 285 kSEK (Fig. 2). The agency capital after 2012 for faculty funded research for both Quaternary and Lithosphere and Paleobiosphere Sciences display positive figures.

This trend was broken in 2012 with a drop of almost 5 million SEK. In 2012 there were a number of successful research applications. Svante Björck, Anders Scherstén and Ulf Söderlund all received significant amounts for most thrilling projects in Swedish Research Council’s general call (Table 2). The total amount was 7.7 million SEK which is 1.7 million SEK more compared to 2011.

The trend of increasing external funding betweem 2004 and 2011 was broken by a drop in 2012 by 4,570 million SEK. 2011. In a special call from the Swedish Research Council for French-Swedish collaboration Svante Björck and Dan Hammar-lund were successful and receive 2,653 and 2,7 million SEK crow respectively for three years (Table 3). The outcome of applications to the Geological Survey was also successful for the Department with three approved projects, to Helena Alexandersson, Anders Scherstén and Ulf Söderlund (Table 4). From the FORMAS geoinfra-call Torleif Dahlin at Lunbd Technical university, as main applicant, with Charlotta Sparrenbom and Håkan Rosqvist as co-applicants has been granted almost 7 milion SEK for 5 years for the project "Geoelectrical Imaging for Site Investigation for Urban Underground Infrastructure“. Torleif Dahlin, as main applicant, and Charlotta Sparrenbom as co-applicant has been granted 1.6 million SEK from Lund Tachnical University infrastructure for a walk TEM-equipmewnt, a new GPR-equipment and a DCIP. The application for a High Resolution LA-ICP-MS from the Science Faculty infrastructure call was unfortunately turned down but an improved application ha been submitted for the 2013 call. The extensive research activity is reflected in numerous ways. In 2012 altogether 112 papers (90 in 2011) were published (p. 33) in peer reviewed scientific journals, some of which in very prestigious journals like Science, Nature Geoscince and Plos One. This is 20% more compared to 2011. In 39 of these (43%) researchers from geology were first author. A total of 120 conference abstracts (p. 39) were submitted in 2012 with researchers from geology as first author in c. 70%. Considerable international collaboration and activities are also reflected in several other parameters. In 2012 the Department was visited by more than 35 scientists from all over the world (Table 10, p. 46). Several researchers from geology did more than 50 international travels and visits (Table 8, p. 44) and participated in 47 international conferences and workshops (Table 9, p. 47). Several field expeditions were carried out to various parts of the globe e.g. Chile, Ghana, Vietnam, Greenland and Botswana (Table 11, p. 46 ) and 1 conference/workshop was organised (Table 12, p. 48). The gender equality committee is a joint unit between Department of Geology and Department of physical Geography and Ecosystem Analysis. The committee consisted in 20121of 7 persons from both departments (Table 5). The Gender and Equality plan for 2012 the was approved by the two Department Boards. The gender- and equality committee organised in November an interactive theater performance with the group Puman/Nya Klassiska Teatern that was attended by 35-40 participants. Eleven women participated in a 1-day seminar for women in worklife - ”Kvinnor i tiden”. With the end of December 2012 my six years as head of department has come to an end. In all respects it has been very inspiring but also very intense years. I think that these years personally have been very developing and I have come to know a number of persons both within and outside the department which has been most stimulating. Of all duties that comes with this position staff related issues and problems, probably are the single task that has taken up most of my time and most of my energy. The previous head of department, Per Möller, struggled for many years with a huge negative agency 2 Annual Report 2012 Table 5. Members of the gender equality committee 2012. Table 3.

I think a number of reasons can explain this very encouraging development. A lot of work has been devoted to develop the bachelor and master programs by introducing a number of new courses. The labour market for students with a degree in geology has been most positive. We have a most qualified group of teachers. Of the lecturers 75% are professors all who are engaged in research. The generally open and positive attitude at the Department was reflected in e.g. the "Studentbarometern" which shows that students in geology are the most satisfied students at the faculty with their teachers (Table 3:2 Renehed 2011). In June 2012 our former student administrator Margaretha Kihlblom received the students Honorary Award for "extraordinary services to the students". At the same occasion Hans Jeppsson was awarded the students Pedagogic Award. In the evaluation last year of the Swedish National Agency for Higher Education of all bachelor and masterprograms in geosciences in Sweden both our bachelor and our master program received the top grade - very high quality as the only university in Sweden. Another most significant and positive thing worth mentioning is that over the last six years we have built up a well functioning, very professional administrative unit jointly with our sister department Physical Geography and Ecosystem Analyses. I think we can all be very proud of our Department with top quality research and education as well as qualified administrative and technical support. The role as head of a department is most complex and complicated and requires among other things a true interest for staff and administration. I am convinced that Mikael Calner is a most competent successor and I wish him and the Department all the best for the future. Lund April 2012 capital, a problem that was more or less solved when I succeeded him in 2007. In retrospective the last six years have in most respects been a fantastic period of expansion. The department has received two KVA scholars (Raimund Muscheler and Vivi Vajda) and Daniel Conley was appointed Wallenberg scholar in 2011, all three most prestigious appointments. That money, along with several other grants, has allowed Daniel Conley to develop a strong research group in biogeochemical cycles and environmental change especially in the Baltic Sea. Other new research fields that has emerged over the last six years are e.g. palaeooceanography and marine geology, astrobiology, impact research, and molecular palaeobiology. In the RQ08 (Research Quality Assurance for the Future) evaluation most of the research group were considered oustanding. The number of teachers with permanent position has increased significantly during the last six years. Most of all the lecturers have been promoted to professors. The first female professor in geology was Charlotte Möller, appointed in 2009. Researchers, generally on short term contracts, have like PhD students increased significantly due to the increasing external grants. Basic education has seen a similar expansion as research. The number of student have doubled from just over 100 "full time year student equivalents" in 2007 to almost 200 in 2012. In 2007 there were 7 applicants to the geology program, a figure that Table 4. Successful applications to the Geological Survey.

Courses in geology 2012. From the 1st of July 2007 a new study and degree structure was introduced in Sweden following a European standardisation system for higher education (the Bologna program). The first three years of undergraduate studies (basic level) leads to a Bachelor of Science in Geology (Fig. 7) and the following two years (advanced level) to a Master of Science in Geology (Fig. 8). The undergraduate studies at the geology programme starts with 4 mandatory courses in basic geology (yellow in Fig. 7). These are followed by elective courses according to the choice of each student (blue in Fig. 7). Two of the elective courses must be outside geology. To obtain the first degree a Bachelor Theses corresponding to 15 credits is mandatory (half a semester or 10 weeks work). At the two year master program there are two main specialisations: Bedrock geology and Quaternary geology (Fig. 8). The master program includes a Master Thesis corresponding to 3/4 year (45 credits) of full time studies. Code Courses Credits Period • • • • • • • • • • • In 2012 the department taught 40 courses (including degree theses, Table 4). Global and regional maringeologi (15 hp VT1) was introduced as a new master course. In total 32 bachelor (13) and master thesis (19) were presented in 2012 (Table. XX) compared to 22 in 2011. Teachers from the department also supervised a number of theses for students from the Department of Environmental Sciences specialising in geology. Our master student Samer Bou Dahers received a prestigious price from the Geological Survey of Sweden for the best thesis in 2012 presented at a Swedish university The number of students starting studies in geology has significantly increased since 2007. The last two or three years there has typically been 40+ students studying on program.

Post-graduate studies The research education in geology is a joint program within the GeoBiosphere Science Centre (CGB). There are two specialisation in geology, Lithosphere and Paleobiosphere Sciences and Quaternary Sciences The research education is focused on Earth systems and their development through space and time and aims at the understanding of the Earth from processes of the geobiosphere on geological time scales, through present day climate-ecosystem interactions, predictions of future changes in climate and the functioning of the Earth. The post-graduate education includes four years of studies and leads to a PhD exam in one of the three main specialisations. After two years it is possible to obtain an intermediate exam called "Licentiate". A research education committee organises the post-graduate education consisting of representatives from the three specializations and three PhD student, chaired by the director of graduate studies, in 2012 Jonas Ardö at the Department of Physical Geography and Ecosystem analysis. The committee also coordinates the planning of PhD courses, seminars and other PhD study activities. In 2012 Johan Olsson in Lithosphere and Paleobiosphere Sciences and Daniel Fredh inQuaternary Sciences (Table 7) defended their doctoral theses. 2008-2012 was a period of rather few dissertations per year (average 2.1) compared to the previous five year period 2003-2007 with with an average of 6.2. For the upcoming years again rather high numbers can be expected. For 2013 at least 7 PhD defences can be expected. The number of PhD students today is around 30 hwich is about 50% higher than only five six years ago. In 2012 four new PhD position were opened and for 2013 there will be at least another four new positions. Johan Olsson.

At present the performance of the SSAMS system is as follows. Precision: ± 50 14C-years; maximum datable age: ca. 48,000 BP; minimum sample weight: ca 0.1 mg of carbon. Supplier is National Electrostatics Corp. (NEC), Wisconsin, USA. The equipment was funded by the Knut and Alice Wallenberg Foundation and by the Swedish Research Council. Special laboratories Radiocarbon Dating Laboratory The Radiocarbon Dating Laboratory in Lund performs dating on geological and archaeological samples. Examples of material that we date are wood, charcoal, peat, macrofossils, bone and marine shells. The analyses are based on Accelerator Mass Spectrometry (AMS). Natural 14C can be used in numerous applications, of which radiocarbon dating, with the possibility for dating back to about 50,000 years, is the best-known and most practiced application. Radiocarbon dating is based on the property that the activity concentration of 14C in dead tissues can be used to calculate the time that has elapsed since death occurred. This is possible since all living organisms contain nearly the same proportion of radioactive carbon in their carbon stores and since, upon the death of the organism, the carbon which survives decomposition continuously loses 14C by its radioactive decay. Most samples are first pretreated according to the acid-alkali-acid (AAA) method. The samples are washed in hot diluted HCl followed by hot diluted NaOH solution. The dried organic samples are then combusted to CO2 and transported to a graphitizing reactor where it is mixed with H2 gas. The reduction to elementary carbon takes place over a hot (580 °C) Fe catalyst. The carbon-iron mixture produced in the reactor is pressed into a small Al cylinder and put into the ion source of the AMS machine. As part of the LUGEOCLOCK project, a new fully automated graphitization equipment (AGE-3), directly coupled to an elemental analyzer, was installed during the autumn of 2012. The AGE machine, which has been developed at ETH Zürich, will produce more homogenous samples and has a higher capacity than the old graphitization system. The carbon isotope ratios are measured in an Accelerator Mass Spectrometer, which was installed at the GeoBiosphere Science Centre in 2004. It is a compact and highly automated machine and based on some new technology – ‘Single Stage Accelerator Mass Spectrometry’ (SSAMS). An upgrade to improve the background and the ability to measure ultra-small samples was made in February 2009. To date (January 2013), around 5000 samples for radiocarbon dating have been analyzed on this ma- Staff: Göran Skog (head of laboratory), Pia Sköld, Mattias Olsson and Mats Rundgren. Laboratory home page: http://www.geol.lu.se/c14/ Palaeomagnetic/Mineral Magnetic Laboratory The Palaeomagnetic and Mineral Magnetic Laboratory (PMML) houses a range of equipment designed for research in ‘environmental magnetism’. The laboratory was rebuilt in 2011 to accommodate a new long-core 2G Enterprises 760-Superconducting Rock Magnetometer (SRM), which is now operating. One room is dedicated to an 2G Enterprises 755-SRM and a Magnetic measunements Ltd thermal demagnetizer. The second room contains, in addition to the 760-SRM, a Princeton Measurements Corporation alternating gradient magnetometer and a wide variety of other equipment items, such as magnetic susceptibility (MS) bridges, pulse magnetizers and a long-core MS surface scanning conveyor. Laboratory staff members are engaged in a wide range of projects, such as (i)magnetostratigraphic studies of Quaternary age lake sediments in Australia and New Zealand, (ii) the identification of nanometre scale particles in Baltic Sea sediments and (iii) IODP expedition #347 ‘Baltic Sea Paleoenvironment.’ Head of laboratory: Ian Snowball Laboratory homepage: http://www.geol.lu.se/palmag 40 Ar/39Ar Geochronology Laboratory The 40Ar/39Ar method is a tremendously versatile and powerful geochronometer which has been used to date K-bearing rocks and minerals as young as a few 10’s of thousands of years to the oldest rocks on Earth. Argon for 40Ar/39Ar analysis can be released either by step-heating a sample (single grain 11 Annual Report 2012 Head of laboratory: Helena Alexanderson Staff: Rajendra Shrestha (master student) Home page: http://www.geol.lu.se/osl/ or rock aggregate) using a furnace or a defocused laser and by in-situ Laser Ablation of a small ≥ 2 micron spot. The main components of the 40Ar/39Ar laboratory consist of a Micromassociate-5400 Gas Source Massociate Spectrometer with a faraday and an electron multiplier. A custom designed and built UHV gas metal extraction line, which contains two SAES C50-ST101 Zr-Al getters and a cold finger cooled to ca –155°C by a Polycold P100 cryogenic refrigeration unit. For gas extraction the 40Ar/39Ar laboratory is equipped with the New-Wave Dual-Laser system which contains two lasers: a high wavelength CO2 laser and a UV laser. The CO2 Laser can be used for incremental heating on single or multi-grain aggregates or total fusion of a sample; while with the UV laser, specific spots on a crystal may be fused or ablated and an age estimated. A double vacuum furnace from Modifications Limited may also be utilized. The entire analytical process is automated and runs on a Macintosh with software modified specifically for the laboratory and developed originally at the Berkeley Geochronology Center by Al Deino. Mineral Separation Laboratory Efficient techniques for mineral separation are important in almost all geochronological studies. From year 2000, we have used the so called “waterbased technique” for separation of baddeleyite (and zircon). Baddeleyite is a reliable geochronometer for dating the crystallization of mafic and other silicaundersaturated rocks. The technique is based on the observation that small grains move much slower than large grains as they move across a Wilfley water-shaking table. In addition to the efficiency in extraction of very small (≤ 30 µm) baddeleyite grains, the water-based separation technique reduces the risk of cross-contamination, and is less costly (e.g., no heavy liquids are necessary) than conventional techniques. Over the years, baddeleyite from more than 70 samples of dykes and sills in Fennoscandia, Canada, South Africa and Zimbabwe have been successfully recovered in our lab. Typical yields for these rocks have been 200-300 grains/fragments per 0,5-1 kg sample. Head of laboratory: Anders Scherstén Staff: Laurence page Laboratory homepage http://www.geol.lu.se/ar/ Head of laboratory: Ulf Söderlund Home page: http://www.geol.lu.se/minsep/ Microfossil Laboratory Department of geology houses one of the finest laboratories in the world for processing microfossils. Through decades of continuous refinement and development, primarily by Professor Emeritus Lennart Jeppsson, we are now able to process very large samples (up to more than 100 kg each) and get very concentrated sample residues that will significantly decrease picking time. Using buffered and diluted (c. 10%) acetic acid that will easily digest different types of limestone without etching phosphatic microfossils. After dissolving the rock slabs the residues are treated further, for example magnetic and/or density separation, depending on what end product is requested. The technique is primarily developed for phosphatic microfossils (such as conodonts and fish scales) but works very well also for organic-walled microfossils such as scolecodonts, chitinozoans, and graptolites. Other rest products obviously include silicified, phosphatized and pyritized fossils and acid resistant mineral grains. Luminescence Laboratory Luminescence dating is a geochronological technique that spans the Late Quaternary. It is particularly useful for minerogenic sediments, for example as optically stimulated luminescence (OSL) dating of quartz and infrared stimulated luminescence (IRSL) dating of feldspar. Thermoluminescence (TL) dating can also be used to determine the age of pottery. TheLundLuminescenceLaboratorywasestablished last year, as the first of its kind in Sweden. It houses a Risø TL/OSL-reader model DA-20, with options to do OSL, pulsed OSL, IRSL and TL. In the adjoining rooms mechanical and chemical preparation of samples can be carried out under darkroom conditions. In 2012, the laboratory received 69 samples, of which 30 came from external users. Ongoing research projects at the laboratory concerns i.a. the timing of aeolian deposition in Skåne and interstadial periods in northernmost Sweden and on Svalbard. 12 Annual Report 2012 The head of the laboratory, Git Klintvik Ahlberg, has years of experience of extracting acid resistant microfossils.

The status as a national resource unit implies that the laboratory serves as national centre for research and education within the special field of competence. The laboratories are funded by the Research Council (VR) and by the Faculty of Science at Lund University. Laboratory for Ceramic Research The research at this laboratory includes mainly ceramic/archaeological research. This activity serves the archaeological science with technological investigations of ceramic artefacts. The aim of the technological analyses is to establish the choice of raw materials, manufacturing techniques and vessel function. In combination with studies of vessel shape and decorative elements it is possible to shed light on questions concerning provenance and distribution of prehistoric and medieval ceramic materials. By combining the results of several independent analyses, it is possible to gain information concerning the handicraft as well as contacts and relations between different groups of people. Furthermore, the Laboratory for Ceramic Research serves as a centre of education in the field of pottery documentation and registration. Several courses are given each year to groups of students and to individual researchers. The laboratory has well-established collaboration with archaeological institutions and museums in northern Europe and participates in an international ceramological network, the Society for Archaeological Ceramology (SAC). Laboratory for Wood Anatomy and Dendrochronology Research at the laboratory also includes palaeoclimate reconstruction based on tree-ring series (dendroclimatology), commonly as an integrated part of other palaeoecological and palaeoclimatic research at the department. Two major research projects are carried out at present: 1) A VR-funded project (SweDenClim) which aims at establishing a representative reconstruction of climate variability and change at sub-decadal resolution for the interior of southern Sweden from AD1000 to the present. This work is based on stable carbon- and oxygen-isotope analysis of wood cellulose extracted from pine tree-ring series. A follow-up project (HACIDYS) aims at characterizing large-scale, centennial- to millennialscale changes in atmospheric circulation across the Scandinavian Peninsula during the Holocene, and to attribute these changes to external and internal forcing mechanisms. This work includes proxy-data compilation and comparisons with regional model simulations incorporating water-isotope diagnostics. 2) Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits. Apart from highly resolved (sub-decadal to annual) and accurately dated records of hydrological status of peat deposits in southern Sweden, this project aims at extending existing regional pine dendrochronologies and filling gaps between previously obtained floating chronologies. Head of laboratory: Anders Lindahl Laboratory home page: http://www.geol.lu.se/ kfl Other laboratories Besides the special laboratories and national resource units mentioned above researchers at the division have access to well designed laboratories and sophisticated equipment for various types of analyses. 13 Annual Report 2012 Lithosphere and Paleobiosphere Sciences fully characterize mineral phases, identify reaction mechanisms, estimate reaction kinetics for both endogenic and exogenic processes at the micro- to nanometer scale. Mineral-oriented research includes studies of chemically and biologically induced weathering processes and of the resulting finegrained minerals. The Earth’s crust is essentially formed by magmatic processes and to a large extent reworked by deformation, metamorphism/re-melting and weathering. Present-day research is directed towards magmatism, plate reconstructions, large-scale deformation and terrane analysis in time and space. Besides field observations and measurements, this research is heavily dependent on geochemical, isotopic and mineralogical data. In igneous petrology, attention is devoted to melt evolution by differentiation, assimilation of crustal material and magma mixing under various geodynamic regimes. Studies in metamorphic petrology are integrated with isotope geology and structural geology in order to unravel pressure-temperature-time relationships. The main tools we use for absolute dating are the radiogenic U-Pb and Ar-Ar decay schemes. These methods permit us to obtain age information on the timing and rate on continental crust formation, the thermal history of sedimentary basins, neotectonic uplift of General research program The formation of the Earth, changes in the Earth’s climate and the evolution of life are preserved in the rock record. Our research focuses on interdisciplinary studies of processes and conditions in the lithosphere and on the Earth’s surface throughout geologic time. Research topics are currently diverse and embrace several of the principal disciplines of geology. Our principal research deals with igneous and metamorphic petrology, tectonics, geochronology, isotope geology, carbonate and clastic sedimentology, chemostratigraphy, event stratigraphy, biostratigraphy, palaeoecology, and applied and environmental geology. Such research has a global perspective with work undertaken on material from all continents. International co-operation is carried out within various organizations and projects, such as the International Union of Geological Sciences (IUGS), International Commission on Stratigraphy (ICS), the International Geoscience Programme (IGCP), the Swedish Polar Research Programme, and the International Lithosphere Programme (ILP). We further have a strong link to applied geology via research on building materials, dating of mineralization, CO2 geo-sequestration, geothermal energy, and improved stratigraphic controls on hydrocarbon resources. Research sub-programmes and research groups: 1. Deep Crustal processes 2. Reconstruction of Super-Continents through time and space 3. Extraterrestrial influence on the evolution of Earth 4. Climate change: Evidence from the Geological record 5. Evolution of Marine and Terrestrial Ecosystems 6. Earth Resources – their sustainable development Within the research themes “Deep Crustal processes” and “Reconstruction of Super-Continents through time and space” the following studies are performed; Mineralogical studies are based on scanning and transmission electron microscopy and synchrotron based methods. The techniques are combined to Coffee break while doing field work in south Eastern Greenland. Photo: M. Nilsson. 14 Annual Report 2012 young mountain ranges like the Alps and the Andes. Combined with paleomagnetic studies, the dating of major dyke swarms provides key information for break up of supercontinents and reconstruction of cratons on a geological time scale. The Ar-Ar method is used to date extrusive rocks and moderate to low temperature events, the latter of which is important for reconstructing the youngest thermal and dynamic history of the crust. Within the research themes “Evolution of Marine and Terrestrial Ecosystems” “Extraterrestrial influence on the evolution of Earth” and “Climate change: Evidence from the Geological record” central topics are: The emergence of life and the evolution of fauna and flora on a geological time scale; and climate change through Earth’s history as seen in the sedimentological record of both marine and terrestrial ecosystems. Our work also has an astronomical perspective whereby detailed mineralogical and chemical studies of extraterrestrial particles provide information about the history of the solar system, and the possible relationship between the evolution of life and astronomical processes. Research fields include an integrated approach of sedimentology, sequence stratigraphy and geochemistry. This research aims to reconstruct the evolution of ancient sedimentary basins in order to document environmental changes on local, regional and global scales. Particular emphasize is paid to fossil reef ecosystems that forms excellent archives for changes in physical oceanography as well as palaeoecology. We study Paleozoic biotas and their relationships to environmental changes as this time interval embraces some of the most significant evolutionary events in Earth history, setting the agenda for the development of modern life. This includes the study of marine fossils such as trilobites, which are used as tools to assess biodiversity, paleobiogeographical patterns and to aid stratigraphic correlations in the Cambrian. Other groups such as Paleozoic teeth of proto-vertebrates and polychaete jaws also provide key data for the global correlation of Paleozoic strata. This research is coupled with investigations of the earliest land plant assemblages adding to our understanding of the terrestrialization of life and its impact on atmospheric CO2 and O2 levels and global climate. From Mesozoic marine sediments we investigate the evolutionary trends among aquatic reptiles such as mosasaurs and elasmosaurs. From contemporaneous continental strata we study the diversity, biology and palaeoecology of dinosaurs and other reptiles together with the vegetation in their environments. These studies help chart the evolution of life through the Mesozoic in relation to changes in climate and continental configuration. Our goal to ever more precisely chart the appearances and extinctions of organisms in the rock record also provides us with improved tools for dating and correlating rocks between regions. Studies of changes in the Earth’s environment through deep time provide important new perspectives on present global change. Apart from periods of stasis or gradual change, Earth has experienced numerous abrupt environmental catastrophes during the last 500 million years. The Cretaceous-Paleogene (KT) mass-extinction event, which occurred 65 million years ago as a consequence of an asteroid impact, is being investigated and provides a model system for interpreting biotic turnover during other crises for life on Earth. Reconstructions of biogeochemical and physical feedback processes during these events result in a better understanding of the conditions for life on Earth. Much focus in this research is on the history of the carbon cycle and its relation to biodiversity and climate. Understanding the long-term carbon budget and the significance of different carbon sinks and sources through time is a prerequisite for understanding present carbon cycling.

Nilsson. 20 Annual Report 2012 Quaternary Sciences e.g. Rogen, De Geer and Niemisel moraines, and investigate their sedimentology and structural geology with the purpose to set up process-facies models for their formation. Geomorphology is used to better understand the dynamic behaviour of the Scandinavan ice sheet and for an increased knowledge of the local deglaciation history. We also monitor and describe present-day sub- and supra-glacial processes to study the integration of sediments - processes and the resultant landforms as a function of climate at the margin of modern glaciers. The latter is done in close collaboration with the DNA/Geology group in Copenhagen. General research program The basic research is concentrated on physical, chemical and biological changes and processes of the Quaternary time, mainly based on well-dated terrestrial and marine stratigraphies. The main aims are paleoenvironmental, paleoclimatic and paleogeographic reconstructions, and to analyse and understand underlying causes behind local, regional and global changes and their impacts. The main purpose is to gain an increased understanding of the complex Earth System and its most recent geologic history. From the Nordic region we have extended our field studies to Russia, to central, eastern and southern Europe, to Siberia, Iceland, Faroe Islands, and other North and South Atlantic islands, Greenland, Svalbard, to North and South America, New Zealand and Antarctica. Marine studies are growing and have been performed in the Baltic and North Sea, the Atlantic Ocean and the China Sea. We emphasize international cooperation in research and education. We therefore take an active part in different Nordic, European and global programmes. Applied research is also performed, particularly within the Master´s programme, but lately also within the research programme, such as hydrogeological research questions. Understanding and modelling of how, e.g., pesticides are spread to and within deep groundwater aquifers is one such current and active research field in Quaternary Sciences. 2. Reconstruction of Quaternary environments in Polar and mid-latitude regions - paleoglaciology and climate history In the Polar regions the glacial history of the last two glacial cycles - Saalian and Weichselian, i.e. from isotope stage 6 and upwards, are studied in order to identify some of the processes behind the growth and decay of ice sheets, duration of the individual ice-sheet advances and their role in climate changes on the northern hemisphere. The methods are those of traditional Quaternary glacial geology, utilizing all kinds of remote sensing, morphological, sedimentological, and palaeontological information and most available methods for absolute and relative dating. The group currently works in Siberia, Greenland, Svalbard and Argentina. The Siberian and Greenland (LongTerm) and Svalbard studies are incorporated into the APEX programme. The Argentinian work is conducted within the VR-funded ATLANTIS project. The main partners for the Siberian and Greenland work are (AARI) in St. Petersburg and the DNA/ Geology group in Copenhagen. Research sub-programs and research groups: 1. Glacial processes, sediments and landforms This group has multiple research interests, emphasizing the relationship between processes, sediment products and landforms of ancient and modern glacial environments. We study the glacier dynamical behaviour of the last Scandinavian ice sheet. In South Scandinavia, dynamic glacial reconstructions are attempted based on the sedimentation and landscape evolution during Late Weichselian ice-lobe advances. At the former southwestern margin of the ice sheet the focus is directed towards gaining a better insight into drainage conditions during the termination of the last Scandinavian ice sheet. As a part of this programme we also study the formation of specific landforms, 3. Hydrologic, biogeochemical, physical, biotic and atmospheric response to climatic changes and analyses of their triggering and feedback mechanisms, including climate modeling. With a crossdisciplinary-multistratigraphic approach we reconstruct past climate and environmental variability from lake, marine and peat records. This includes sedimentology, stable isotopes, mineral magnetic 21 Fieldwork in Taymyr ( SWEDARCTIC 2012 ) - unloading Mi8 helicopter on Taymyr Peninsula, Siberia. Photo P. Möller. past land-coverage. Development of a methodology combining pollen/vegetation calibration, dispersal and deposition models, historical maps, archaeological findings and GIS makes this possible. It is applied to study long-term dynamics of land-cover changes within lake catchments areas and its affects on terrestrial biodiversity and aquatic ecosystems, incl. the Baltic and other marine coastal areas. The group has currently projects in different parts of the Nordic region, Kamtjatka and on Atlantic islands. parameters, biogeochemistry, trace elements, XRF analyses, an array of biological proxy records, stomata analysis, and multivariate and spectral analyses. High resolution 14C dating, dendrochronology, laminated sediments, and detection of tephra horizons are the main tools in establishing detailed chronologies, and for calculating atmospheric 14C changes. Leads and lags between different responses are analysed to evaluate possible triggers and couplings between different interlinked processes. Correlations to ice cores and marine records, and quantifications and modeling of past conditions constitute important parts of these studies. The investigations cover the entire last interglacial/glacial cycle. The group has currently co-operative research projects in Sweden, Denmark, Faroe Islands, The Azores, Grenada, Tristan da Cunha, Tierra del Fuego (Isla de los Estados), Southern Ocean (incl. sub-Antarctica), Greenland, Russia, eastern and southern Europe as well as global perspectives. 5. Late Quaternary geomagnetic field variability, cosmogenic radionuclide production and reconstructions of solar activity, including modeling of solar activity and climatic processes We analyze paleomagnetic records and cosmogenic radionuclides abundant in tree rings, ice-cores and sediments to improve our understanding of (i) the geomagnetic dynamo, (ii) changes in element cycles and (iii) solar activity and its relation to climate change. Reconstructions of past solar magnetic activity are based on estimates of radionuclide production rates in the atmosphere, which need to be corrected for the modulating influence of the geomagnetic dipole strength. Differences between the abundances of different nuclides in ice-cores (10Be, 36Cl) and treerings (14C) are studied to reveal changes in element cycles caused by circulation changes in the ocean and atmosphere. We work with sediment and ice cores records from both hemispheres. 4. Biosphere-climate-human-interaction and its temporal and spatial variation We study biologic and biogeochemical changes in both terrestrial and aquatic (fresh-brackish-marine) environments, mainly in the Holocene, by means of multidisciplinary methods involving pollen and plant macrofossil analysis, testate amoebae and pigment analysis, osteology, environmental magnetism, biogenic silica, foraminifera and geochemistry etc. We also develop methods for translating sediment samples of the surrounding landscape into maps of 22 Annual Report 2012 6. Sea-level changes Research is concentrated on Late Glacial to Holocene land-uplift and sea-level changes within the area of the Fennoscandian and Greenland glaciations as well as southernmost Tierra del Fuego. The aim is to record relative sea level history, and from that interpret causes in terms of glacio-isostasy, eustasy, and neotectonic movement, but also to analyse and model the postglacial Greenland ice sheet history. The field area is southern Sweden, Denmark, East Baltic area, northernmost Sweden, south Greenland and lately also Tierra del Fuego. A close cooperation exists with ANU in Canberra to use shoreline data bases for modeling of the Greenland and Scandinavian uplift history. (e.g. radionuclides, palaeomagnetism and pollution isochrones). We are also active further afield, e.g., applying environmental magnetic methods to palaeoceangraphic studies of sediments from Disko Bay, western Greenland. Two additional aspects of our work are: environmental and climate reconstructions of different marine environments, such as the upwelling region off NW Africa, using benthic foraminifera but also studies of culture- and field foraminiferal based proxy calibration to improve climate reconstructions. 8. Biogeochemical cycles and environmental change Our research is focused on nutrient biogeochemical cycles, especially Si, and the linkages between land and aquatic ecosystems. We investigate the accumulation and recycling of Si on land in soils from deposition of plant phytoliths and in aquatic ecosystems as diatoms, which delays the export of weathering products from the continents to the oceans. We are studying long-term trends in biogeochemical cycles driven by climate and nutrients, and how ecosystems respond to changes in the drivers. The group is particularly interested in weathering and the linkages between CO2 and Si. We are making significant advances in our understanding of the controls of long-term climate variations through the study of interactions between the global biogeochemical cycles of C and Si. In our research we measure pools and fluxes of elements, in addition to stable isotope measurements of Si. The groups current research activities take place in the Baltic Sea, Brazil, Canadian Arctic, the global oceans, Hubbard Brook Experimental Forest (NH, USA), Iceland, Okavango Delta (Botswana), and Svalbard. 7. Palaeoceanography and marine geology Over the past few years we have expanded our interest in the marine environment. We are active in the EU-FORMAS funded BONUS+ program and study the evolution of the Baltic Sea, including the impact of human activity on this sensitive ecosystem. Investigations focus on reconstructing the distribution of hypoxia in time and space, including the impact of salt water inflows on stratification, and natural gas storage in the sea bed. A crucial aspect of these studies is geochronology and we apply a variety of dating techniques to produce accurate and precise timescales 9. Groundwater processes and contaminants Our groundwater research focuses on occurrence, fate and behaviour of organic and inorganic contaminants in groundwater and sediments within the groundwater system, as well as changes in groundwater quality over time. The research has during 2012 focused on three different topics (i) occurrence and longterm behavior of pesticides in groundwater (the Pegasus project) and (ii) arsenic mobilization in groundwater and the pollution of drinking water resources in the Hanoi Area, Vietnam (the Amonas project) and (iii) age determination and mixing of groundwater and its relationship to contaminants.
