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 seasonal Arctic sea-ice retreat was quite rapid in the first week of July but slowed during the rest of the month (see Fig.1). The mean extent for July 2021 was 7.72 million km 2 . As such, it was
After a two-year break, this year experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) were able to return to Station Nord in northeast Greenland, to resume
In September, the summer sea-ice melting ends in the Arctic. In other words, on a certain day of the month, the sea-ice cover reaches its lowest extent for the year and then begins growing again, beca
But this year, February was extraordinarily warm. Analyses of satellite and station data indicate that very warm air has been advected towards the Arctic, which allowed temperatures to rise until the
It was an unforgettable welcome: when we came in from the Arctic cold (-25°C) and first set foot in the entrance area of Canada’s CFS Alert station, the entire staff, decked out in their best uniforms
“May 2018 was the warmest May in Germany since 1881, and the second consecutive month (together with April 2018) with a new record high.” That was the German Weather Service’s review of the current we
CryoSat-2, a radar altimeter satellite of the European Space Agency (ESA), had its eighth birthday on April 8, 2018. Observations from CryoSat-2 add vital information on sea ice thickness to other sat
