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

In arctic environments with permafrost, seasonal changes 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.
