      strong influence of humans on the natural conditions. To understand the climate system prior to anthropogenic influence, we have to follow another path and employ methods of paleoclimatology. Proxies provide

    • Past polar sea ice variability

      biomarker-based reconstruction of sea ice, which provides important information on: natural (non-anthropogenically induced) sea ice variability and associated climate variability; Changes in marine primary

      and biological pumps of carbon will shift in future, hence whether changes in climate due to anthropogenic greenhouse gas emissions will be amplified or dampened. As physical oceanographers we are inv [...] that the Weddell Sea bottom water became warmer during the last decades, and that its content of anthropogenic CO2 increased continuously; by detailed investigations it could be shown that the densest part

    • North Sea Office

      The North Sea is one of the most heavily used seas in the world. Shipping, fishing and other anthropogenic activities have substantial effects on natural ecosystems, while also influencing the North Sea’s

    • Research projects

      Research (DAM) through its sustainMare research mission, is developing concepts for reducing anthropogenic stresses on marine ecosystems and biodiversity. The project brings together 32 experts from 15

    • Rapid surge in global warming mainly due to reduced planetary albedo

      this sudden rise has proven a challenge for researchers. After all, factoring in the effects of anthropogenic influences like the accumulation of greenhouse gases in the atmosphere, of the weather phenomenon
