Before this, different test campaigns are planned, including a shorter

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

into the climate history of the 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
