The motor of this ice transport is the transpolar drift, a major current that pushes ice from the Russian marginal seas of the ArcticOcean over the North [...] process constantly produces new sea ice in the Laptev Sea, which then finds its way to the ArcticOcean. The Arctic ice machine only shuts down in May, when even northeast Siberia grows warmer - and starts
an ice floe When will the Arcticocean be ice free? Why did the sea ice cover of the Southern Ocean grow during the last years? And how is marine life changing, when the Arctic sea ice is getting thinner [...] thickness with the so-called EM-Bird or the Ground-EM, researchers take advantage of the fact that ocean water has a much higher conductivity than sea ice. Therefore both devices are able to measure the [...] reference measurements. Under ice sonar An acoustic transmitter and receiver unit is moored to the ocean floor to measure its distance to the sea ice. A changing distance indicates changes of the sea ice
icebreaker Polarstern will drift through the ArcticOcean, locked in the ice. During the MOSAiC expedition, experts from 17 nations will observe the Arctic in the course of an entire year, and will overwinter

roughly two-thirds of global sea-level rise; the remaining third is primarily due to the warming of the oceans, which causes seawater to expand. Accordingly, the development of our planet’s ice sheets and glaciers [...] and that ice-loss processes have been set in motion that will have lasting consequences. In the Arctic, temperatures are rising twice as quickly as the global average; as a result, the Greenland ice sheet’s
the impact of the Arctic on global climate. In addition to this major campaign, numerous field work activities take place every year in the mainland Arctic and in the adjacent ArcticOcean. The coast plays [...] drifting Observatory for the Study of Arctic Climate ). From fall 2019 to fall 2020, the German research icebreaker POLARSTERN drifted frozen through the ArcticOcean. The data collected will be valuable [...] Ecological processes in the terrestrial Arctic: Prof. Dr. Ulrike Herzschuh • Permafrost processes in the Arctic: Prof. Dr. Guido Grosse • Atmospheric processes in the Arctic: Prof. Dr. Markus Rex AWI Research

Ocean Eddies In a new study, researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) investigated the long-term changes in the ArcticOcean eddy activity [...] study reveals a remarkable surge in Arctic eddy activity in a warmer climate, a trend that is probably unparalleled when compared to other regions across the global ocean.
referred to as the “Arctic amplification” of climate change: the Arctic is warming nearly three times as fast as other regions of the Earth. The environmental changes that lie ahead for the Arctic will be more [...] entail socioeconomic changes in the Arctic... Of course, there are interests in using the Arctic for commercial purposes: for tourism, for example. A trip to the Arctic, a region that’s not easily accessible [...] the Arctic in winter. Nevertheless, we can expect more cruise and container ships in the Arctic. When it comes to fishery, there will be a lot of changes, too. If the “Atlantification” of the Arctic continues
icebreaker Polarstern has been drifting through the ArcticOcean for a year since autumn 2019. Scientists from 20 nations explore the central Arctic over the course of the year on the MOSAiC expedition [...] It goes without saying that the waters of the outer Arctic ice aren’t subject to the same pressure as in the inner ice, let alone the Central Arctic; the floe dimensions are on a different scale, too.
