Biogeochemistry in Coastal Seas

Within the division “Biogeochemistry in Coastal Seas” several departments investigate the sinks, sources, dispersion and fate of pollutants in the atmosphere and in marine and coastal waters. We study biogeochemical processes in shelf seas sediments and estuaries, quantify sediment water interaction and assess the role of sediments in the cycling of nutrients, organic matter and organic and inorganic pollutants.

The results are used to fill into the marine geoportal "coastMap", which collects and concentrates data of physical, biochemical and bological conditions of the sea floor in the German Bight. State-of-the-art sampling tools, analytical instruments and numerical models support are used to analyse emissions, transport and accumulation of pollutants, nutrients and persistent chemicals in the coastal sea.

In shallow shelf seas like the North Sea or the Baltic Sea, important ecosystem functions occur at the sea floor. Sediments at the seafloor interact with the overlying water and regulate the cycles of matter, sequester pollutants and providing habitats for marine flora and fauna. They are also archives for reconstructions of past environmental conditions.

The App of the division "Biogeochemistry in Coastal Seas"

Coastal research is a complex research area of major societal importance. This is becasue our coasts and coastal seas are influenced by a variety of natural and human induced influences. In coastMap web application the scientists of the division on "Biogechemistry in coastal seas" present central foci of their research. to coastMap App
