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
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
“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
In October, the sea-ice extent in the Arctic was once again below the double standard deviation from the long-term average (Fig. 1). In September 2018 the ice covered an average area of 4.43 million s
Recent findings show that the ability to predict the location of the Arctic sea ice edge varies considerably among sub-seasonal forecasting systems. The best of these forecasting systems outperforms t
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
In February, the sea-ice cover in the Arctic remained below the double standard deviation from the long-term average (see Figure 1) and followed a similar progression as in the years 2007 and 2018. In
The dramatic loss of ice in the Arctic is influencing sea-ice transport across the Arctic Ocean. As experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research report in
