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.

CCZO区域斯通牧场深层地下水井的水位深度数据集。该地下水井坐落于一片大体平坦的宽阔河间地块，钻井取芯深度约70米，井套管终止于约17米深度处。本数据集采用Solinst levellogger（3001 LTC）型压力传感器进行连续监测，采样分辨率为20分钟。下载获取的原始数据为传感器上方的正水深值。随后通过与该井共址部署的Solinst barologger（3001型）同步采集的大气压数据完成气压校正：该气压记录仪与压力传感器采用相同采样频率记录大气压，校正方式为从原始水深值中扣除大气压对应的水位偏移量。最后，借助每次数据下载时通过水位计手动测得的地面以下深度，将校正后的传感器上方水深值转换为相对于地面的地下水位埋深。
