Thickness and properties of sea ice and snow of land-fast sea ice in Atka Bay in 2017@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. […]研究人员每2至4周便会沿横跨阿特卡湾（Atka Bay）的25千米长测线，均匀布设测量点位并重复开展人工测量，测定的参数包括海冰厚度、冰下血小板层（sub-ice platelet layer）厚度、冰面干舷以及积雪厚度。在每个测量点位，均会钻取5个冰孔以测定上述参数：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，以此覆盖该区域的小尺度空间变异性。……
