Research focuses on areas in the Arctic and sub-Arctic, the Arctic Ocean, the Southern Ocean and Antarctica. The studies include reconstructions of ice sheet dynamics, oceanic circulation and tectonic processes

The permanently frozen soils of the Arctic store tremendous amounts of carbon in the form [...] not consumed by marine animals, including dead marine microorganisms, material transported to the oceans by rivers –the particles that trickle down are deposited layer by layer at depth. Ultimately, a unique [...] deposited on the seafloor, leaving clues that enable the AWI geoscientists not only to reconstruct the Arctic’s climate history, but also to understand the role of thawing permafrost in past climate changes.

Biodiversity
Massive sponge gardens thrive on top of seamounts in the Central Arctic Ocean, one of the most oligotrophic seas on Earth. They appear to feed on the remnants of an extinct fauna. Micr [...] Communications . They stress the need for a better understanding of the diversity and uniqueness of Arctic ecosystems in the light of global and local change.

More melt water is entering the Artic Ocean from the glaciers due to climbing temperatures. In addition, the rivers are carrying large amounts of sediment from thawing permafrost. How the [...] the Arctic Ocean will react to such changes is a very big question, which is concerning scientists around the world.
