Thaw depth time series from a station at Levinson-Lessing Lake

Depth of active layer was measured at 10 plots in a 100x100 m grid (ordinal number=cell number). At each plot four samples were taken within a square meter every week.本研究在100×100米的网格内的10个样地开展了活动层（active layer）厚度测量，其中样地的序号即为单元格编号。在每个样地内，每周均在1平方米范围内采集4份样本。
