They have now published three overview articles on the MOSAiC atmosphere, snow and sea ice, and ocean programs in the journal Elementa, highlighting [...] together. These results present the first complete picture of the climate processes in the central Arctic which is warming more than two times as fast as the rest of the planet - processes which affect weather

In these zones magma rises from the Earth’s interior to the surface, cools down there [...] magma again. A region in which new seafloor continuously forms is, for instance, Gakkel Ridge in the Arctic. This is a submarine mountain range whose northern foothills extend from the northeast tip of Greenland

Observed ocean-ice/snow-atmosphere processes: improved knowledge and existing model shortcomings WP1 will produce integrated knowledge of how sea ice and its snow cover are coupled to oceanic and atmospheric [...] deliver improved understanding of the physical, chemical, and biogeochemical interactions within the Ocean-Ice-Atmosphere (OIA) system, new knowledge of polar and global climate, and enhanced ability of society [...] components and regions (e.g. polar low-latitude interactions/teleconnections) that occur through the ocean and atmosphere. Finally, we use existing and updated model projections to complete a comprehensive

To prove if they [...] leads and polynias For the energy and moisture exchange between the atmosphere and the ice covered ocean, leads and polynias play an important role. This is documented by many modelling studies, but only [...] sea ice have a significant effect on the energy exchange between the atmosphere and the ice covered ocean. Uncertainties in the representation of sea ice albedo contribute considerably to the differences

between atmosphere and ocean. This concerns both hemispheres since cold-air outbreaks occur in the Arctic and Antarctic as well. Typical regions for cold-air outbreaks in the Arctic are the Fram Strait and [...] of the lower atmosphere with sea ice and ocean is strongly influenced by processes caused by the surface morphology, which is characterized in the Polar ocean regions first of all by the sea ice cover [...] over Arctic leads, Q.
