The thickness of sea ice determines the heat exchange between the ocean and the atmosphere as well as the resistance against the deforming forces of wind and ocean currents. Already a thin layer of se
After the sea-ice extent in the Artic reached its winter maximum on 12 March 2019, the melting season in the North Pole region began and soon reached an all-time low for the time of year (23 April 201
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
Accordingly, being familiar with the different types of sea ice is important for a range of activities, including navigation at sea, modelling the ice-ocean-atmosphere system, and the remote sensing o
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
On 11 September the sea-ice extent (sea-ice concentration > 15 %) was 3.94 million km² (see Figure 1) and on 3 September 2019 it had already decreased to 3.82 million km², the lowest level so far this
Sea-ice conditions in the first half of October 2019 In mid-September, the autumnal sea-ice formation process began in the western Arctic Ocean (see Figure 1). Sea ice extent is with 4.97 Mio. km² far
According to analyses from the University of Bremen’s Institute of Environmental Physics, the mean sea-ice extent in the Arctic this October was only 5.44 million km², which is more than 443,000 km² b
