Groundwater and active layer measurements at permafrost sites (DP1.20099.001)

Up to eight shallow groundwater wells per site are installed in inter-tussock areas surrounding the lake and stream reaches to capture groundwater flow paths. Wells are pushed down to thaw depth on a weekly basis and hand measurements are reported for depth to water and depth to thaw relative to the ground surface. Instrumentation:

每个监测点最多可布设8口浅层地下水井，设置于湖泊及河段周边的草丘间区域，以捕捉地下水流路径。每周将井下放至当前融解深度，并通过人工测量获取相对于地表的水位埋深与冻融深度数据。监测仪器配置：
