Functioning of marine ecosystems strongly depends on nutrient supply. One of the key sources of nutrients in the Black sea is rivers runoff, concentrated mainly on the northwestern shelf (NWS). Due to surface currents waters from NWS propagate into deep part of the basin and transport nutrients into interior basin. Study of this exchange of water mass and nutrients between the NWS and the deep part of the Black Sea is a goal of this work. It is based on the results of numerical modelling evolution of physical and biogeochemical fields of the Black Sea. The interdisciplinary model of the Black Sea ecosystem consists of a circulation model and a biogeochemical one, describing the interactions between different components of the marine ecosystem. It is shown, that nutrient fluxes between NWS and deep sea are defined by intensity and character of surface currents, which depend on regional wind stress vorticity.
