With the return of the Russian research icebreaker “Akademik Treshnikov” to the port of Murmansk, Russia, another successful chapter in Russian-German collaborative Arctic research drew to a close. On
During the MOSAiC expedition, researchers from 19 countries will study the Arctic throughout an entire year, spending the winter in a region that is virtually inaccessible in the polar night. Alone th
Development in the Arctic The slight upward trend following the Arctic minimum continued in early 2024; although the sea-ice extent was below the mean value for the years 1981 – 2010 at the beginning
Research aircraft from the Alfred Wegener Institute have been surveying the ice-covered Arctic Ocean for 30 years. The immense effort of the past 52 expeditions has paid off: 40,000 km of measurement
Relevance of melt ponds In the Arctic summer, the sea ice melts due to rising temperatures and constant sunlight. When it does, meltwater can gather in pools on the surface, known as melt ponds. These
Sea ice cores from the MOSAiC expedition (2019-2020) are one of the treasures that were brought back to Bremerhaven at the end of the year-long Arctic drift in October 2020. Now, a group of scientists
The further sea-ice retreat will chiefly depend on the ocean temperatures and on wind patterns, which can either condense or disperse the sea ice. As the summer draws to a close, the surface of the ce
The stratosphere is the part of our atmosphere beginning at an altitude of ca. 10 km, and where, thanks to the absorption of the trace gas ozone, temperatures rise with increasing altitude. Normally,
Despite a storm and the adverse ice conditions, he and his team reached the MOSAiC floe almost as planned. They left the floe on 16 May and reached the sea-ice edge on Tuesday, 2 June. Now Torsten Kan
Ever since, atmospheric researchers Dr Dörthe Handorf and Dr Annette Rinke at the AWI in Potsdam have been searching for concrete evidence of the interrelations between the sea ice, polar air currents
