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

Furthermore, she also coordinated Sylt & Helgoland [...] Helgoland and Sylt.
