• Oasis of life in the ice-covered central Arctic

    the ice of the Arctic, unknown habitats conceal an unexpected variety of living beings. On October 23rd, 46 scientists are expected to return to the home port in Bremerhaven from an Arctic expedition with [...] with the research vessel Polarstern. Over the past six weeks, they had explored life in ice, ocean and seabed with new robots and camera systems.

  • Nutrient Chemistry of the Arctic Ocean

    AWI scientist Sinhué Torres-Valdés observed the nutrient chemistry of the Arctic Ocean on an expedition as part of the PEANUTS project (Primary production driven by Escalating Arctic NUTrient fluxeS). The SCRIPPS Institution of Oceanography led the expedition in 2018. The results have now been published in a paper in the journal Nature Communications. The PEANUTS project is funded by the Changing Arctic Ocean Program (CAO).

  • 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

  • New tools and concepts to observe the changing Arctic Ocean

    observation of ice, ocean and seafloor processes in the Central Arctic. A main aim is to observe and analyse the changes in the sea ice cover, and its causes and consequences for ocean and life.

  • New equipment for the AWI - "Gardener"

    towards Spitsbergen, to use newly developed equipment in the Arctic Ocean. Autonomous instruments on the seabed, in the water column and in the air will complement the long-term measurements of the deep-sea research [...] RV Polarstern starts the Arctic season
    Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) are setting out with the research vessel Polarstern towards [...] research group. In this way researchers can analyse the climatic changes in the Arctic and their impact on the fauna in the future with higher temporal and spatial resolution.

  • 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

  • More and stronger marine heatwaves in the Arctic – with severe consequences

    becoming more frequent and intense. The Arctic Ocean also suffers from this development: The absence of sea ice will lead to more extreme fluctuations in ocean temperatures, with abrupt temperature changes [...] Wegener Institute shows how marine heatwaves will also become much more intense and frequent in the Arctic in the 21st century. With drastic consequences for the ecosystem. The researchers published their

  • Micro- and nanoplastic from the atmosphere is polluting the ocean

    , e.g. in water bodies, the soil and the air. Via ocean currents and rivers, the tiny plastic particles can even reach the Arctic, Antarctic or ocean depths. A new overview study has now shown that wind [...] the Institute for Advanced Sustainability Studies in Potsdam, and the GEOMAR Helmholtz Centre for Ocean Research in Kiel – describes how microplastic finds its way into the atmosphere and how it is subsequently

  • 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.

  • Making the Arctic accessible for excellent science

    forces to improve the capacities for marine-based research in the ice-covered Arctic Ocean. In the project “ARICE- Arctic Research Icebreaker Consortium”, they aim at better coordinating the existing polar
