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

A main focus is to carry out multidisciplinary field studies and experimental work in the deep Arctic Ocean. In December 2008 a Joint Research Group for Deep-Sea Ecology and Technology of the Helmholtz [...] Marine Microbiology ( MPI-MM ) in deep-sea research, and to set up a new research focus on the deep Arctic Ocean.

Using unique sediment samples from the Lomonosov Ridge, the researchers found that six to ten million years ago the central Arctic was completely ice-free during [...] winter, however, the ocean was covered by sea ice of variable extent, the scientists explain in the current issue of the journal Nature Communications. These new findings from the Arctic region provide new
