world, there are natural climate archives – the sediments on the ocean floor, ancient ice in the Arctic and Antarctic, wood for tree-ring analyses, and more. These archives contain what is referred to [...] However, these models do not reflect in detail processes in the ocean, which have a major influence on the climate. In response, the AWI has developed a special ocean model (FESOM), which simulates e.g. ocean currents and sea ice. For their climate simulations, AWI researchers have coupled the two atmospheric models and FESOM, yielding

the framework of intergovernmental bodies (eg SCAR, IASC, ATCM, Arctic Council, CCAMLR, OSPAR). The office is coordinating the AWI contributions and will perform as an information platform for environmental [...] networks (DAM, DKK, Helmholtz Climate, KDM, UN Decade of Ocean Science, IPCC, IPBES, Leopoldina, etc.), in which the research contributions of the AWI / of Helmholtz Earth system research are of

We study the consequences of increasing water temperatures on species interactions in Arctic benthic coastal communities. From these investigations we predict future scenarios for a warmer marine Arctic ecosystem and its [...] from the Interreg North-West Europe Programme.

In these zones magma rises from the Earth’s interior to the surface, cools down there and constantly [...] seafloor continuously forms is, for instance, Gakkel Ridge in the Arctic. This is a submarine mountain range whose northern foothills extend from the northeast tip of Greenland to Laptev Sea in Siberia.

For this [...] our research on changes in the atmosphere, the cryosphere, the ocean and the coast, corresponding feedback mechanisms as well as the consequences of climate change for polar and marine ecosystems and [...] significance of the UN goals for sustainable development for oceans and polar regions and to keeping these issues present in the public consciousness.

We operate cutting-edge measurement systems across the Arctic and Antarctic, using research vessels, such as the icebreaker Polarstern , observatories, aircrafts, and satellites to capture the evolving dynamics of the ocean, atmosphere, sea ice, and ice sheets. At the same time, we push the boundaries of climate modeling – one of our key strengths – by
