parts of North America – reaching an ice thickness of more than 3 km, before it finally melted at the end of the ice age. To date, there have been few detailed studies of the evolution of the North American [...] that in particular the snowfall in summer favoured the growth of the ice sheet and influenced the sea level.
25 September - 1 October 2017 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.
transect, Polarstern bit its way through heavy sea ice, hard as concrete and covered with a thick layer of snow. This altogether slowed down our progress into the north significantly. During our journey in the

Sediments, and even small pebbles and bivalves, were incorporated into the ice during the freezing process, which the on-going melting process has brought to light on

Cape Verde Islands at 26 ° C, a cloudless sky and a gentle swell of 2 meters from the north. The hard-earned “sea legs” can rest for now, it could really be worse.
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
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

Due to rising water temperatures, many Arctic fish species are retreating farther and farther north, while species from more temperate latitudes are increasingly being sighted off the coasts of Greenland [...] Institute have now analysed scientific publications on the ecological impacts of climate change in Arctic seas released in the past ten years. Their findings: the shifting habitats have affected entire biotic
