• Greenland 2016

    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
