Interannual variability of the exchanges between the continental shelf and the open sea: High resolution simulation of the Gulf of Lions' dynamics

Questions of global change entail elucidation of the processes that determine the exchanges between coastal ocean and deep sea. Fluxes across ocean shelves are dominated by complex coastal dynamics and in the microtidal site of the Gulf of Lions, mixing and dispersion are dominated by interactions between coastal processes (freshwater dynamics associated to the Rhône river discharge, coastal upwellings, dense water formation and cascading) and the North Mediterranean shelf current.

To know how these processes operate and interact, a regional model of the Gulf of Lions has been integrated over the 10 year period 1990-2000. The model is based on the NEMO code, with a 1/64 resolution and 130 vertical z-levels.

The numerical outputs allow us to investigate the interannual variability of the coastal circulation and uxes across the shelf break and then to strike a balance of the exchanges at the Gulf of Lion's margin over a quasi-climatic period.
