CJCZO -- Piezometer, Groundwater Depth -- Marshall Gulch -- (2007-2019)

30 minute groundwater depth data are derived from pressure measurements at 15 locations (7 at the granite site and 9 at the schist site) and corrected for barometric pressure measured at the schist site. Pressure is measured using Onset Hobo pressure transducers model U20 placed at the soil bedrock interface in vertical plastic tubes that were drilled into the soil.本数据集包含的30分钟分辨率地下水埋深数据，源自15个监测点位的压力测量结果（其中花岗岩场地布设7个点位，片岩场地布设9个点位），并已依据片岩场地实测的大气压力完成校正。压力测量采用Onset Hobo品牌U20型压力传感器，传感器安装于打入土壤的垂直塑料管内的土壤-基岩界面处。
