Eutrophication is the anthropogenic pressure with the greatest effect on the Baltic Sea ecosystem. Research about nutrient enrichment is an area where we are particularly strong, both at a coastal scale and for the Baltic Sea as a whole.

One main research focus is eutrophication of the Baltic Sea and its catchment. We investigate nutrient pathways in various watersheds and estuaries of the Baltic and, large-scale phosphorus and oxygen dynamics in the sea, and assess the environmental status of the Baltic.

At the Baltic Sea Centre we have strong experience and in-house expertise in the relevant fields of geochemistry, biogeochemistry, oceanography, modelling, biology, agronomy, and systems ecology. Many of our experts also participate in successful international projects that address issues related to eutrophication.

Research area goals: 

Develop and increase knowledge about:

1. the state and development of the coastal sea area
2. modeling of the Baltic Sea ecosystem
3. how large-scale and long-term processes in the Baltic Sea affect carbon and nutrient turnover, oxygenation and sea acidification during climate change, and
4. effective measures to decrease eutrophication of the Baltic Sea

Our researchers and technicians within Baltic Nest Institute (BNI) continuously develop and improve the model-tool that is used as basis for the eutrophication parts of the Baltic Sea Action Plan (BSAP).
