Groundwater well pressure, temperature, conductance, salinity and oxygen measurements for GCE-LTER study hammock PC_i_29 from 15-Aug-2008 to 13-Dec-2013

Groundwater pressure, temperature and other parameters (e.g. conductance, salinity, oxygen and pH) were measured using various instruments installed in PVC wells at the GCE-LTER PC_i_29 pleistocene study hammock from 15-Aug-2008 to 13-Dec-2013. Observations were logged continuously at 15 minute intervals, and accumulated data were downloaded from loggers using manufacturer-provided communications software semi-monthly, then imported into MATLAB for post-processing, quality control and documention. Raw, unvented pressure readings were corrected for atmospheric pressure and sensor height from the bottom of the well to generate corrected pressure readings. Separate data tables are provided for each combination of instrument and well due to differences in parameters measured and post-processing steps, but all tables include detailed information on location and well characteristics to support integration and analysis. These data were collected as part of the Georgia Coastal Ecosystems LTER Intensive Hammock Characterization and Hammock Groundwater Modeling projects, and will be used for groundwater modeling studies at two marsh hammocks on Sapelo Island, Georgia.2008年8月15日至2013年12月13日，研究团队依托安装于佐治亚海岸生态系统长期生态研究（GCE-LTER）PC_i_29更新世研究湿地高地的聚氯乙烯（PVC）井中的多类仪器，对地下水压力、温度及其他参数（如电导率、盐度、溶解氧与pH值）开展监测。观测数据以15分钟间隔连续记录，研究人员每半月通过仪器厂商提供的通信软件从数据记录仪中导出累积数据，随后将数据导入MATLAB进行后处理、质量控制与文档整编。未经通风处理的原始压力读数需针对大气压力及传感器距井底的安装高度进行校正，以生成校正后的压力数据。鉴于不同仪器与井组的监测参数及后处理流程存在差异，本数据集为每一组仪器-井组合单独编制数据表，但所有数据表均包含点位与井体特征的详细信息，以支撑数据整合与分析工作。本数据集采集自GCE-LTER"湿地高地精细化表征"及"湿地高地地下水模拟"项目，将用于佐治亚州萨佩洛岛两处沼泽高地的地下水模拟研究。
