Groundwater and active layer measurements at permafrost sites (DP1.20099.001) : RELEASE-2021
In arctic environments with permafrost there is a seasonal change in active thawed layer and liquid water that drive the hydrology of the system. This seasonal freeze/thaw cycle causes frost heaving of groundwater wells, making measurements of groundwater elevation inaccurate due to sensor movement....

| Summary: | In arctic environments with permafrost there is a seasonal change in active thawed layer and liquid water that drive the hydrology of the system. This seasonal freeze/thaw cycle causes frost heaving of groundwater wells, making measurements of groundwater elevation inaccurate due to sensor movement. Therefore, this data product contains measurements of depth to liquid water and thaw relative to the ground surface made manually rather than using a sensor that would require a fixed elevation throughout the season. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage. : 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. |
