the scientists could demonstrate that the Arctic Ocean as well as the Nordic Seas did not contain sea-salt in at least two glacial periods. Instead, these oceans were filled with large amounts of freshwater [...] Geosciences
The Arctic Ocean was covered by up to 900 m thick shelf ice and was filled entirely with freshwater at least twice in the last 150,000 years. This surprising finding, reported in the latest

German Norwegian Ocean Forum
From the Arctic to the North Sea: this year’s German Norwegian Ocean Forum was held in Bremen’s Übersee Museum. The spotlight topic of the symposium, which was jointly organised [...] by the AWI, Innovation Norway, and the Royal Norwegian Embassy, was ‘The sustainable future of our oceans’.

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

seriously impacted the sea-ice cover: in the Russian Arctic (the sector from 30 to 180° East), roughly 1 million square kilometres less of the ocean is covered with ice than in the past seven years.

The Arctic sea-ice extent is the lowest it’s ever been in July since the beginning of satellite observation. The sea-ice retreat is especially pronounced off the Siberian coast, as a result

The ice-covered Arctic Ocean is a more important factor concerning the concentration of the greenhouse gas methane in the atmosphere than previously assumed. Experts from the [...] Research (AWI) report on the newly discovered interactions between the atmosphere, sea ice and the ocean in a recent online study in the journal Nature’s Scientific Reports.
