dc.description.abstractThis study presents the results on the ongoing work of the physical-biogeochemical modeling of the Mediterranean Sea. In particular, we examine three sub-domains of the Aegean Sea (eastern Mediterranean Sea). These three areas within the North Aegean Sea present physical and biogeochemical contrasts throughout the year. The first sub-domain is close to the mouth of the Dardanelles Strait, where cold, brackish and biomass-rich waters, originally from the Black Sea, enter the Aegean Sea. The second area is located within the Thermaic Gulf (northwest Aegean Sea at the Greek coast) in the same latitude as the Dardanelles Strait but in the opposite (west) Aegean coast, where a number of rivers discharge. The third sub-domain is located offshore in an area with neither rivers nor Dardanelles direct and immediate interaction. The three areas present relatively active seasonal cycles and hydrodynamics but they display different biogeochemical seasonal regimes. We have selected them to examine the descriptive capability of the coupled physical-ecosystem model to simulate biogeochemical regimes with different occurrence times, nutrient-rich waters inputs, and wind regimes. They constitute, therefore, a suitable laboratory for comparison and validation of the coupled model results with sea surface temperatures and chlorophyll-a distributions derived from satellite observations. We use the 3-D General Estuarine Transport Model (GETM model) to simulate the hydrodynamics in the Mediterranean Sea. The results from this 3-D model force the 1-D ecosystem model that simulates the biogeochemical regimes in the selected sub-basins. We have design and carried out multiannual simulations from January 1985 to December 2006 with horizontal resolution 5¿x5¿ for the physical model, and from October 1997 to December 2006 for the coupled system. The beginning of this time window corresponds to availability of the SeaWiFS and MODIS chlorophyll-a distributions used for model validation and discussion at sea surface. This report is organized as follows: section 2 describes the methodology and the data sets examined, section 3 presents the results and discussion on their validation, and the conclusions and future work are given in section 4.en_GB
