Over past decades, the Southern Ocean has substantially slowed global surface warming [...] Postdoc My aim is to better understand the ocean carbon sink and its changes, with a special focus on the Southern Ocean. I study how the physics of the ocean impact the return pathways of CO 2 to the surface [...] that Antarctic Winter Water plays in the Southern Ocean.

Understanding these processes – especially in the rapidly changing polar regions where the changes

Sea ice motion and deformation Sea ice can be found in the Arctic and Antarctic, but also for example in the Gulf of Bothnia and Finland, is very dynamic. The drift velocities of individual ice floes or [...] other deformation features have a major impact on the interaction between the atmosphere, sea ice and ocean. They also pose dangers for ship traffic. Among other things, our work focuses on the improvement [...] landscape in the Lena delta (© NASA / Landsat , 2000) (Photo: Alfred Wegener Institut) Charting the Arctic Tundra Polynias Terra Nova Bay Polynia (© NSIDC / Modis, 2013) (Photo: Alfred Wegener Institut)
