During these 20 years, 10 year-long drift studies in the Arctic Ocean are planned. The work is based on the collaboration of an international and interdisciplinary [...] Station was baptized in Lorient, France, in April 2025 and will realize the first drift in the Arctic Ocean starting in summer 2026. Before this, different test campaigns are planned, including a shorter

sail for a six week expedition to the Central Arctic Ocean initiated by “ART”. ART, in this case, does not stand for artistry but is the abbreviation for Arctic in Rapid Transition, an international research [...] research network established by early career scientists working in the Arctic.

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

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.
