HF Radar System-IOI-Malta Operational Centre
CALYPSO HF Radar Monitoring System for the Malta Channel Presented by Adam Gauci on behalf of Aldo Drago (Project Leader) Physical Oceanography Unit, IOI-Malta Operational Centre, University of Malta [email protected] [email protected] AIS Ship Traffic Data MEDESS4MS Project The CALYPSO Project HF Radar Monitoring System and Response against Marine Oil Spills in the Malta Channel Two HF-Radars and combining station on the Maltese Islands. One HF-Radar on the Southern Coast of Sicily linked to the central station. Measure 2D sea surface currents and waves in the Malta Channel. The area of interest is about 95km wide. 13MHz CODAR system. The CALYPSO Project The project brings together 4 partners from Malta: University of Malta (UOM) Transport Malta (TA) Civil Protection Malta (CPD) Armed Forces of Malta (AFM) and 4 partners from Sicily: ARPA Sicilia IAMC-CNR Capo Granitola Università degli Studi di Palermo (UNIPA) Universita’ Di Catania (CUTGANA) Radar Site Selection - Ta’ Barkat Malta In Malta, the radar is installed at Ta’ Barkat, limits of Xghajra. Permission was obtained to place the equipment within the premises of the Water Services Corporation wastewater treatment plant. Data Modem MAC computer Transmitter Receiver UPS Electronics shed Antenna Radar Site Selection - Ta’ Barkat Malta The antenna is erected on the plant’s outflow very close to the coastline approximately 70m away from where the equipment is housed. The mast is raised by about 2m to achieved alongshore coverage and to avoid surrounding terrain. Radar Site Selection - Ta’ Sopu Gozo A site recognition field trip was done along the whole northern coast of Gozo. The optimal place for the antenna was determined to be about 80m west from Sopu Tower at Ta’ Sopu, limits of Nadur. The electronics rack is placed within the Armed Forces of Malta barracks (PP4) about 330m away from the mast.

This has an irregular temporal pattern that reduces the system performance at the time it occurs (normally stronger in the afternoon). The system is currently operating with a 50 kHz sweep UP configuration. Data Validation - Drifters Data Validation - ADCP Six ADCP measurements were made in two separate surveys between Malta and Sicily. Regions in which radial data is available most of the time (>80%) were identified and six points were determined. Data Access - www.capemalta.net/calypso Data Access - Access to Radar Data Data Access - Public Interface The Public Interface is aimed for the general public. It provides plots and statistics for 9 different regions in the Malta-Sicily channel. Information from the current and past 6 hours is obtained from the radar files. The forecasted conditions for the next 6 hours are also provided through the use of the ROSARIO 64 marine forecast. Provided statistics include: Average current magnitude and direction Minimum current magnitude Maximum current magnitude Maximum current magnitude in the last six hours Maximum current magnitude expected in the next six hours Data Access - Drifters Data Access - Professional Interface Data Access - Professional Interface Data Access - Professional Interface CALYPSO HF Radar Monitoring System for the Malta Channel www.capemalta.net/calypso
