Description of research activities

Baltic Sea biogeochemistry
A first research focus deals with the biogeochemistry of the Baltic Sea and its catchment by means of field studies and modelling studies. We address nutrient retention in various estuaries of the Baltic, investigate large scale phosphorus and oxygen dynamics in the Baltic Sea, estimate the environmental status of the Baltic sea some hundred years ago. Moreover, we develop a catchment model simulating simultaneously the nutrient land-sea fluxes from all 105 major watersheds within the Baltic Sea drainage area. The model has been used for the formulation of the Baltic Sea Action Plan (BSAP).
