Simulation of primary production and export fluxes in the Northwestern Mediterranean Sea

摘要

A biogeochemical model, BIOMELL (BIOgeochemical Model of the Euphotic Layer of Lodyc), has been developed to simulate the temporal evolution of the main nitrogen stocks and fluxes at the DyFAMed station (Dynamique des Flux Atmospheriques en Mediterran6e), located in the Northwest- ern Mediterranean Sea. This mainly oligotrophic region is characterized by a strong seasonal cycle, and a significant export of dissolved organic matter compared to the particulate export measured by sediment traps. Validation of the model is made using temperature, nitrate and chlorophyll profiles acquired at DyFAMed approximately every month in 1991.
