  • Coastal carbon sinks protect permafrost material from decomposition

    show, part of the biomass released becomes trapped in deep sinks on the ocean floor off the Arctic coast – where it is protected from microbial decomposition. The outcomes of their analyses are intended [...] Permafrost
    The Arctic is warming more strongly than any other region on Earth, which leads to serious erosion of coasts where organic matter was frozen in the permafrost for thousands of years. Once [...] Once eroded material is released into the ocean, microorganisms break down ancient plant remains, releasing sizable quantities of greenhouse gases. Yet, as the latest analyses conducted by AWI experts show

  • 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

  • The German National Committee for Polar Research meets at GEOMAR

    ecosystems must always keep the polar regions in mind. The Arctic and Antarctic, for example, play a central role in the system of global ocean currents, and the large but shrinking ice sheets are important

  • A fortress of ice and snow

    suitable ice floe, where they will set up the research camp for their one-year-long drift through the Arctic Ocean. Consequently, one of the most important milestones in the expedition has been reached ahead of

  • The seafloor of Fram Strait is a sink for microplastic from the Arctic and North Atlantic Ocean

    concentrations at the ocean floor. Using model-based simulations, they have also found an explanation for this high level of pollution. According to their findings, the two main ocean currents in Fram Strait [...] Marine Pollution
    Working in the Arctic Fram Strait, scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have found microplastic throughout the water column [...] microscopically small plastic particles into the region between Greenland and Spitsbergen from both the Arctic and the North Atlantic. While passing through the Strait, many particles eventually drift to the

  • Polarstern returns to MOSAiC floe

    forward to continuing the one-year-long MOSAiC expedition and its research on the ocean, ice and atmosphere in the Arctic. Earlier this week, their predecessors from Leg 3 returned to Bremerhaven on board

  • Celebrating 40 Years of the Alfred Wegener Institute

    Anniversary
    40 years of research in the Arctic, Antarctic and in coastal regions: on 15 July, the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) celebrates its 40 th [...] and internationally recognised centre for climate research in the two polar regions and the world’s oceans.

  • North pole soon to be ice free in summer

    Climate Research
    The Arctic Ocean in summer will very likely be ice free before 2050, at least temporally. The efficacy of climate-protection measures will determine how often and for how long. These

  • Coastlines’ contribution to climate change possibly underestimated

    result of accelerated climate change, whole sections of coastline rapidly thaw, and erode into the Arctic Ocean. A new study published in the journal Geophysical Research Letters now shows that large amounts [...] of carbon dioxide are potentially being produced along these eroding permafrost coastlines in the Arctic.

  • 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
