Présentation
My main research activity affects the development and the use of models of marine plankton ecosystem. The type of models that is developed reproduces the ecological and biogeochemical interactions arising between the first trophic levels of the microbial community (phytoplankton, bacterioplankton and zooplankton) in the Mediterranean Sea particularly. The development of the latter models and especially, the theoretical representation of the interactions between the planktonic functional key-groups are performed with the help of the experimental specialists on the biogeochemical cycles of nitrogen, silicon, phosphorus and iron.
The models of pelagic ecosystem developed (Eco3M) are coupled with model reproducing the hydrodynamics (SYMHONIE model, NEMOMED12). To couple the two latter types of models is able to assess the impact of the hydrodynamic processes on the spatial and temporal structuring of the planktonic community or also, to assess the amount and the dominant ways of export of the organic matter produced from the euphotic zone.
Another activity of my work is to study the impact of the global change on the planktonic ecosystem through the consecutive alterations of the oceanic circulation. The impact of the climatic variations over an intra-decadal to decadal period has been especially investigated by forcing the coupled hydrodynamic/biogeochemical model with outputs of a meteorological forecasting model.
