CCZO -- Groundwater Depth, Electrical Conductivity -- Calhoun 70-m deep well -- (2014-2017)

Well water depths in deep groundwater well in the Stone's pasture at the CCZO. Groundwater well is situated in a mostly flat, broad interfluve and is cored to ~70m. Well casing ends at roughly 17m. Depths were measured continuously with a Solinst levellogger (3001 LTC) pressure transducer at a resolution of 20 minutes. Downloaded data is in positive depths above the sensor. These depths are corrected for barometric pressure by subtracting barometric pressure measured by a Solinst barologger (3001) which is co-located in the well and records barometric pressure at the same frequency. The data are then converted from depth above the sensor into depths below ground surface using manual measurements of depth below ground made at each download with a water level meter.

该数据集记录了位于中国青藏高原综合科学考察站（CCZO）石头的牧场上深层地下水井的井水深度。该地下水井位于一片相对平坦、宽阔的河间地带，井深约为70米。井筒套管终止于约17米处。井水深度使用Solinst水平记录仪（3001 LTC）的压力传感器连续测量，分辨率为20分钟。下载的数据以传感器上方正值表示的深度。这些深度通过减去与井中同地点的Solinst气压计（3001）测得的气压值进行了大气压力校正。随后，通过在每个下载时使用水位计手动测量的地下深度，将传感器上方深度转换为地表以下深度。
