Field measurements of sea-ice thickness, snow depth, freeboard and sub-ice platelet-layer thickness on the land-fast ice of Atka Bay in 2013@en

We measured sea-ice thickness, snow depth, freeboard and sub-ice platelet-layer thickness by repeated drill-hole measurements between April 2013 and January 2014 at six stations distributed evenly over a transect along Atka Bay. At each measurement location, up to 5 holes were drilled through the sea ice in order to determine the aforementioned parameters, one in the center and one in a distance of five meters in each direction.本数据集于2013年4月至2014年1月期间，在沿阿特卡湾（Atka Bay）的断面上均匀布设6个站位，通过重复钻孔测量获取了海冰厚度、雪深、冰面干舷及冰下血小板层厚度相关数据。在每个测量点位，我们钻取最多5个贯穿海冰的钻孔以测定上述参数：其中1个钻孔位于点位中心，其余4个钻孔分别沿四个方向各距中心5米处布设。
