Manual measurements of sea ice thickness, sub-ice platelet layer thickness, freeboard, and snow thickness are distributed evenly along four transect across Atka Bay in austral summer 2022. At each measurement location, 2 to 5 holes were drilled through the ice in order to determine the aforementioned parameters, one in the center and one in a distance of five meters in each direction, to cover their small-scale spatial variabilities. The measurements have been mainly conducted by the 42nd overwintering team, Jölund Asseng, Stefanie Arndt, and Mara Neudert.
