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
“We are approaching this year’s minimum sea-ice extent in the Arctic, and this summer the ice concentration has descreased to its lowest value since observations started, in 1979,” according to Profes
However, the vast area and the extreme weather conditions make it difficult to monitor the snow during Arctic winter. In situ measurements of snow depth on sea ice are rare and mostly obtained in spri
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

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
