Arctic sea ice-pelagic coupling of the carbon and sulfur cycles

On board the German icebreaker Polarstern, an international team of researchers will spend one year researching the relationship between biological, physical and chemical processes in the sea ice of the North Pole and how these are linked to climate. We want to collaborate in this unique programme through research into the role of sea ice in the sequestration of CO₂ and the production of the climate cooling gas dimethyl sulphide. This project will provide unique insights into the future development of sea ice and how the climate can respond to this. The hypothesis that we will investigate is: will the disappearance of sea ice amplify climate change?
