The Research Vessel Polarstern was in the Arctic for the past seven weeks. There, the summertime sea-ice extent declined by ca. 40 percent over the past 40 years – making it one of the most visible impacts [...] Polarstern investigated Atlantic Water Recirculation in Fram Strait and in the marginal ice zone north of Svalbard, as well as ocean/glacier interactions off the coast of Greenland. Central research questions [...] questions included how the ice conditions, ocean heat fluxes and ocean stratification determine sea-ice melt in the marginal ice zone (between the ice free waters and the dense pack ice) and how the melt

much faster than the rest of the world. With consequences for its sea ice. In order to gauge the thickness of ice masses in the North Pole region, scientists chiefly rely on satellites. But this method [...] now developed a method that, for the first time, makes it possible to identify changes in the Arctic sea-ice thickness for the years 2011 to 2021 – even during the summer months. The resultant data is especially

To what extent does polymetallic nodule mining impact the ecosystem in the deep sea? This is what the MiningImpact expedition SO295 with the research vessel SONNE is investigating for the next two months [...] months in the exploration contract areas of the Clarion-Clipperton Zone in the North Pacific. During the collection of polymetallic nodules, the bio-active layer of the seabed is removed and the sediments

Arctic. Due to rising water temperatures, many Arctic fish species are retreating farther and farther north, while species from more temperate latitudes are increasingly being sighted off the coasts of Greenland [...] Institute have now analysed scientific publications on the ecological impacts of climate change in Arctic seas released in the past ten years. Their findings: the shifting habitats have affected entire biotic

How alarming are the ammunition remnants of two world wars still lying in old wrecks at the bottom of the North Sea and other seas? The EU-funded international project "North Sea Wrecks" investigated these questions, diving to wrecks in the North Sea, taking samples and analysing them. In a symposium on 19 and 20 April 2023 at the Alfred Wegener Institute, the project partners now presented the results. For more information, see this press release from the German Maritime Museum (DSM), which led the project.
