Thickness and properties of sea ice and snow of land-fast sea ice in Atka Bay in 2013@en

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. […]海冰厚度、冰下血小板层厚度（sub-ice platelet layer thickness）、冰面干舷（freeboard）及雪深的人工测量工作，每2至4周沿跨阿特卡湾（Atka Bay）的25千米长断面均匀布设测线并重复开展。在每个测量点位，均会在冰面钻取5个钻孔以测定上述参数：1个位于点位中心，其余4个分别沿四个方向间隔5米布设，以此覆盖其小尺度空间变异性。[…]
