In the Antarctic, the month of February is considered to be high summer in terms of the seasonal decline in sea-ice extent. The extent reaches its lowest point in the year, while in the course of the

“On 8 February 2023, the Antarctic sea-ice extent had reached 2.2 million km² - less than the previous record minimum from 2022. Since the sea-ice melting in the Antarctic will most likely continue in

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

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

Climate change is one of the greatest challenges of our times, and the polar regions are “early-warning” regions for the steadily progressing changes. The Arctic is now warming at three to four times

The decline in summertime sea-ice in the Arctic is an important indicator for the progressive climate change and its effects on the polar regions of the Northern Hemisphere. Since the advent of contin

As our colleagues at the German overwintering station Neumayer III can attest, that doesn’t necessarily mean the weather will get warmer, but at least towards the end of the month they can look forwar

It may come as a surprise, but due to this year’s ice conditions, the Swedish icebreaker Oden had serious difficulties penetrating to the North Pole. The months-long northward ice drift compacted the

After the sea-ice extent in the Arctic showed a moderate loss, hovering in the lower portion of the double standard deviation range from the long-term average with ca. 92,000 km² / day in the first ha

In recent days, the development of the ice cover north of Greenland has attracted considerable attention: within a few weeks, an ice-free strip up to 100 km wide has formed along the coast (Fig.1). Th
