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 af...

Description
Summary: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.
