• Week 6: From East Svalbard towards the deep Arctic Ocean

    started in the marginal sea ice zone east of Svalbard, and then set course north into the central Arctic Ocean.The marginal sea ice zone was mostly covered with decaying sea ice and some larger ice-free areas

  • How the Arctic Ocean Became Saline

    Arctic
    The Arctic Ocean was once a gigantic freshwater lake. Only after the land bridge between Greenland and Scotland had submerged far enough did vast quantities of salt water pour in from the Atlantic

  • Meltwater influences ecosystems in the Arctic Ocean

    Arctic Ocean
    In the summer months, sea ice from the Arctic drifts through Fram Strait into the Atlantic. Thanks to meltwater, a stable layer forms around the drifting ice atop the more salty seawater [...] team of researchers led by the Alfred Wegener Institute has now determined with the aid of the FRAM ocean observation system. Their findings have just been published in the journal Nature Communications.

  • Week 7: In the deep Arctic Ocean

    progress into the north significantly. During our journey in the thick ice across the deepening Arctic Ocean, wildlife became scarcer and scarcer. Patches of Melosira arctica were only spotted rarely.

  • Intensification of Arctic Ocean eddy activity under global warming

    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 Arctic Ocean 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.

  • New dataset reveals biological “treasure trove” of Arctic Ocean

    A major new project will help benchmark biodiversity change in the Arctic Ocean and guide conservation efforts by identifying unique species and assessing their extinction risk. The research led by scientists

  • Which types of jellyfish are there in the Arctic Ocean today – and which will still be there tomorrow?

    research group, which will use cutting-edge technologies to create a jellyfish inventory for the Arctic Ocean. The group will receive financial support from the Helmholtz Association and the Alfred Wegener

  • Heat from Below: How the Ocean is Wearing Down the Arctic Sea Ice

    Arctic Ocean
    The influx of warmer water masses from the North Atlantic into the European marginal seas of the Arctic Ocean plays a significant role in the marked decrease in sea-ice growth, especially [...] evident a year later, when the ice has drifted towards Greenland via the North Pole and leaves the Arctic through Fram Strait. This study also includes data from the MOSAiC expedition.

  • The Arctic Ocean was covered by a shelf ice and filled with freshwater

    the scientists could demonstrate that the Arctic Ocean as well as the Nordic Seas did not contain sea-salt in at least two glacial periods. Instead, these oceans were filled with large amounts of freshwater [...] Geosciences
    The Arctic Ocean was covered by up to 900 m thick shelf ice and was filled entirely with freshwater at least twice in the last 150,000 years. This surprising finding, reported in the latest

  • Long-term observations in the Arctic Ocean
