Abstract: The regional Black Sea Ecosystem Model (BSEM) has been updated to describe better the Black Sea phytoplankton growth specific features, like the strong winter-spring blooms followed by usually less intense blooms in fall. The revised BSEM model includes a phosphorus cycle in order to explore variability of phytoplankton blooms under phosphorus limitation. Two specific features of the upper layer water-column physical and biogeochemical structures have been addressed in the present study. - A detailed view of the large- and mesoscale-circulation characteristics, and thus more detailed interpretation of the spreading and mixing of nutrients is achieved by the use of tracer model simulations. They give us knowledge on the spreading of nutrients and biological matter, coming from the main Black Sea rivers, deep basin pool and intermediate layers, respectively, to the euphotic zone. - BSEM model calibration with constant and variable phosphorous/nitrogen ratio is performed. The relative importance of both fertilizers (nitrate and phosphate) on the phytoplankton growth is shown.
