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
In contrast, the pack ice is now steadily growing in the Antarctic. This year, observations of the sea-ice extent development in both hemispheres reveal a trend clearly below the long-term average. Th
Sea ice is one of the most important components in the Arctic climate system. It is in a state of constant interchange with the atmosphere and the ocean, and its physical characteristics, especially i
An analysis of the first yearly datasets yielded surprising insights into the role of sea ice for life in polar waters. Depending on where and how quickly the sea ice melts, the species makeup and the
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
Since the start of continuous satellite monitoring in 1979, the summertime sea-ice extent in September has been on the decline, showing a loss of nearly 14% per decade, about 50% over the whole time p
At 4.0 million km², the sea-ice extent at mid-month was roughly 530,000 km² above the record low in 2012, and ca. 440,000 km² below the figure for the same month in 2019, the year with the third-lowes
According to the Copernicus Climate Change Service (climate change service of the European Commission and European Space Agency), in Europe the summer months June to August were the hottest since the
