Abstract:
Manual measurements of sea ice thickness, sub-ice platelet layer thickness, freeboard, and snow thickness are distributed evenly and repeated along a 25km-long transect across Atka Bay every 2 to 4 weeks. At each measurement location, 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 meteorologist (Jölund Asseng), Fabian Zahn and Markéta Pokerná, all of the overwintering team.

Comment:
On 2019-11-19 ist was noted, that Freeboard and Snow thickness were interchanged. What was called Snow thickness actually was Freeboard and vice versa. This is corrected now.
