It takes perseverance, a love for detail, and a tremendous amount of stamina, as the findings of a joint German-Russian project now show. In the project, experts from the Alfred Wegener Institute and

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

One and a half years ago the unique Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition , together with its year-round drift through the Central Arctic, came to

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

“May 2018 was the warmest May in Germany since 1881, and the second consecutive month (together with April 2018) with a new record high.” That was the German Weather Service’s review of the current we

CryoSat-2, a radar altimeter satellite of the European Space Agency (ESA), had its eighth birthday on April 8, 2018. Observations from CryoSat-2 add vital information on sea ice thickness to other sat

In January 2020 the mean sea-ice extent was 13.42 million km², i.e., ca. 0.97 million km² below the long-term average for the month (see Figures 1 and 2). In January the ice cover in the Arctic showed

Summary Current predictions by international forecast centres and researchers, collected and evaluated by the Sea Ice Drift Forecast Experiment (SIDFEx), suggest that there is a chance that the drift
