This week started with a disappointment. As a result of very dense sea ice coverage we were unable to recover 3 moorings deployed near the northern edge of the embayment [...] observe the circulation at the transition from Norske Trough in the south to Westwind Trough in the north.

Dear Hartmut, we have largely benefited from your unexpected finding of ice rafted debris in the North Atlantic Ocean. It inspired many researchers [...] our section.

marine deposits, 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 [...] amounts of freshwater under a thick ice sheet. This water could then be released into the North Atlantic in very short periods of time. Such sudden freshwater inputs could explain rapid climate oscillations

The Research Vessel Polarstern was in the Arctic for the past seven weeks. There, the summertime sea-ice extent declined by ca. 40 percent over the past 40 years – making it one of the most visible impacts [...] Polarstern investigated Atlantic Water Recirculation in Fram Strait and in the marginal ice zone north of Svalbard, as well as ocean/glacier interactions off the coast of Greenland. Central research questions [...] questions included how the ice conditions, ocean heat fluxes and ocean stratification determine sea-ice melt in the marginal ice zone (between the ice free waters and the dense pack ice) and how the melt
