The studies include reconstructions of ice sheet dynamics, oceanic circulation and tectonic processes that influenced longterm climate development. We investigate the interaction of tectonic and

With warming in the Arctic expected to be roughly two to four times as high as the global mean, sea ice extent is expected to decline dramatically and induce [...] studies are therefore necessary to understand the response of Arctic coasts to environmental forcing and to better quantify the amount of sediment and organic matter released by coastal erosion.

We operate cutting-edge measurement systems across the Arctic and Antarctic, using research vessels, such as the icebreaker Polarstern , observatories, aircrafts, and satellites to capture the evolving dynamics of the ocean, atmosphere, sea ice, and ice sheets. At the same time, we push the boundaries of climate modeling – one of our key strengths – by
