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
While the Arctic sea ice continues to decline, a glance at the Southern Ocean reveals a different picture: in recent years and decades, the sea-ice extent has increased slightly – albeit with clearly
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
Background Satellite altimeters measure how much the sea-ice surface floats above the water level. This parameter is called freeboard and it is further converted into sea-ice thickness. This calculati
Ever since, atmospheric researchers Dr Dörthe Handorf and Dr Annette Rinke at the AWI in Potsdam have been searching for concrete evidence of the interrelations between the sea ice, polar air currents
Many have seen pictures of the Arctic icescape in the sun, or under the moon during the dark winter months north of the polar circle. Yet, have you ever wondered what it all looks like underneath the
The MOSAiC ATMO (Atmosphere)-Team (Figure 1) made observations of relevant atmospheric properties, processes and interactions over an entire annual cycle while drifting across the Central Arctic with
This was a few thousand km 2 below the previous record low from 1997. The mean sea-ice extent for February, at 2.4 million km², was another historical low (Figure 2). This minimum is the result of ver
