glacier in North East Greenland? To answer this question we needed the bathymetry at the shelf edge of 79th glaciers As ships cannot access this area, we planned a 36 km seismic cross line on the sea ice. This [...] allowed us to collect CTD profiles (Conductivity, Temperature, Density) of the seawater. To get reliable sea ice conditions we left early, in April 2016. Conditions were cold, -25°C to -40°C causing hardware

Ocean waters with salinities below the average [...] balance of the Arctic Ocean. Such waters flow in from the Nordic Seas. An interchange of waters between the Arctic and the Nordic seas results in in seasaw fluctuations in fresh water content between the [...] Current and sea ice flux through Fram Strait. Inflow of saline water from the South is equivalent to a fresh water export. Fresh water from the Arctic strengthens the stratification in the Nordic Seas and the

To this end, we investigate a north-south transect of marine and lake sediment cores spanning the range of the SHW (Fig. 1). From these
