Accordingly, the development of our planet’s ice sheets and glaciers [...] and that ice-loss processes have been set in motion that will have lasting consequences. In the Arctic, temperatures are rising twice as quickly as the global average; as a result, the Greenland ice sheet’s

Intensification of Arctic Ocean eddy activity under global warming

Ocean Eddies
In a new study, researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) investigated the long-term changes in the Arctic Ocean eddy activity [...] study reveals a remarkable surge in Arctic eddy activity in a warmer climate, a trend that is probably unparalleled when compared to other regions across the global ocean.

The environmental changes that lie ahead for the Arctic will be more [...] entail socioeconomic changes in the Arctic... Of course, there are interests in using the Arctic for commercial purposes: for tourism, for example. A trip to the Arctic, a region that’s not easily accessible [...] the Arctic in winter. Nevertheless, we can expect more cruise and container ships in the Arctic. When it comes to fishery, there will be a lot of changes, too. If the “Atlantification” of the Arctic continues

Interview Wunderlich

icebreaker Polarstern has been drifting through the Arctic Ocean for a year since autumn 2019. Scientists from 20 nations explore the central Arctic over the course of the year on the MOSAiC expedition [...] It goes without saying that the waters of the outer Arctic ice aren’t subject to the same pressure as in the inner ice, let alone the Central Arctic; the floe dimensions are on a different scale, too.
