| Objective | The objectives of the related European program were to develop a model of eutrophisation adapted to the contrasting physical and geomorphological environments located throughout Europe, from north to south. These areas include fjords, lochs, bays, gulfs and rias that are subject to different hydrodynamic (tides) and climatic (winds) forcings. Among these sites, the Gulf of Fos was chosen. This gulf is characterized by a microtidal environment highly influenced by the wind. It is eutrophic compared to Mediterranean waters. This site has been extensively studied in the past (SUIVIFOS, SEDIFOS, CHLOROFOS, etc. cruises). Given the acquired data, we proposed to use the model of organic matter recycling that was developed in the context of the European project. This model takes into account both external forcing and local hydrodynamics, and the different physical and biological compartments specific to the Gulf of Fos and that figure in the matter budget. In order to calibrate and validate the model, two intense cruises were planned in Fall 2000 and in Spring 2001 (Tethys II) for integrated water column - sediment studies. Other than the monitoring of hydrobiological variables, these missions involved vertical flux measurements using a particle trap, pelagic production and respiration measurements, oxygen flux and nutrients at the water-sediment interface and, lastly, resuspension measurements, both in situ (at the autonomous benthic measurement data acquisition station - SAMBA) and in the laboratory (flume). This cruise was part of the FP5 RTD European project OAERRE (Oceanographic Applications of Eutrophication in Régions of Restricted Exchanges) and part of ELOISE thematic network (i.e. the European part of the Land Ocean Interactions in the Coastal Zone (LOICZ) Core project. |
