The near−surface ice thermal structure of the Waldemarbreen, Svalbard
Abstract: The near−surface ice thermal structure of the Waldemarbreen, a 2.5−square km glacier located at 78N 12E in Spitsbergen, Svalbard, is described here. Traditional glacio− logical mass balance measurements by stake readings and snow surveying have been con− ducted annually since 1996. The nea...
