During the PS92 cruise, GEM-2 (ice thickness) and magnaprobe (snow thickness) surveys were made during ice stations. A detailed list of performed GEM-2 and magna probe surveys is given in the cruise report (Peeken 2016). The data was used to make assumptions on the stability of the floe, as well as to get insight into the ice and snow thickness distribution at the ROV and dive sides. For further development of the method of EM sea ice thickness retrieval, GEM-2 data were acquired on 2 deformed sea ice structures along 40 meter transects. Round about 260 bore holes were drilled in order to measure freebord and sea ice thickness and validate the GEM-2 data. Snow thickness information were obtained with the magnaprobe.
