Abstract

As part of the JRC marine research activities, a model of phytoplankton productivity has been implemented and applied to an area off Northwest Africa, characterised by a strong upwelling activity. In the model, the daily rate of photosynthesis in the water column is computed through its known dependence on available light and biomass. Irradiance at the sea surface is computed from a spectral atmospheric radiative model, adapted for oceanographic applications. The model takes into account the spectral composition of the underwater light field, as well as the vertical distribution of biomass which is derived from Coastal Zone Colour Scanner (CZCS) data. Results are obtained in terms of new and total production. The advantages and the reliability of such models to monitor phytoplankton productivity in highly dynamic coastal areas are discussed.
