For days, fast sea ice had slowed the progress of the resupply icebreaker Kapitan Dranitsyn; bound for the North Pole, her mission was to support the second exchange of researchers and crew in

export of sea ice and relatively fresh water through Fram Strait depend on these sea ice properties. A feedback loop connects oceanic heat transport, winds and sea ice transport in the Greenland Sea (Kovacs [...] of the Arctic Ocean. Such waters flow in from the Nordic Seas. An interchange of waters between the Arctic and the Nordic seas results in in sea saw fluctuations in fresh water content between the basins [...] water we employ ocean sea ice and large-scale Earth System models. The models are validated using sea ice drift estimates from satellite remote sensing and regional airborne sea ice thickness measurements

with a coupled ocean-sea ice model (North Atlantic Arctic Ocean Sea Ice Model, NAOSIM) show a destabilisation of the halocline due to increased freezing in polynyas of Arctic shelf seas. We are planning to [...] of the coupled atmosphere-sea ice-ocean system during different sea ice regimes as a function of spatially heterogeneous surface properties (e.g., albedo, temperature, sea ice, and snow thickness). These [...] global climate models. A focus will be the Barents Sea, where strong surface heat fluxes foster low sea level pressure and shallowdepth export of water and sea ice. The export is compensated for by a corresponding

After our storm on last Friday, the sea only calmed down very slowly and station work was only possible with two CTD stations in the late night towards [...] made about 60 km to the West of the spreading centre on its flank. There, the seafloor is parted by North-South orientated, parallel faults covered by young sediment, and we discovered both in the sediments
