Thickness and properties of sea ice and snow of land-fast sea ice in Atka Bay in 2012


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.Version 2, 2018-04-26.The measurements have been mainly conducted by the meteorologist (Thomas Schmidt) and Meine Kühnel during the overwintering. During a subsequent summer campaign, the measurements have been conducted by Mario Hoppmann, Priska A. Hunkeler and Stephan Paul.

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