CCZO -- Soil Moisture, Soil Redox Potential -- Calhoun Experimental Watersheds 2, 3, 4 -- (2014-2015)

These are the output data from surveys of watersheds 2, 3, and 4 with a Dualem 2 electromagnetic induction (EMI) probe. The probe was carried along the contour of the slope and recorded georeferenced measurements of specific conductance every one to two seconds. These measurements were started in November of 2014 and continued to be made every two months for a year after (November 2014 – September 2015) by Caitlin Hodges. EMI provides information on soil specific conductance, which can then be used to infer soil moisture and texture conditions. When repeated measurements are made, soil moisture changes over time can be observed. This raw data is best utilized by importing into ArcMap and interpolating the specific conductivity measurements to generate a 2D map of soil conductivity. Hodges used the data to inform her installation of her rusted steel redox indicators in the watersheds to assess soil redox potential in the watersheds (first deployment, October 2015).
Date Range Comments: Measurements made every 2 months

本数据集收录了流域2、3、4的电磁感应（EMI）探测器的输出数据。探测器沿着坡面轮廓移动，每隔一至两秒记录一次地物参考的比电导率测量值。自2014年11月起，Caitlin Hodges每隔两个月进行一次测量，直至2015年9月（2014年11月-2015年9月）。电磁感应技术提供了关于土壤比电导率的信息，这些信息可用于推断土壤含水量和质地状况。通过重复测量，可以观察到土壤含水量随时间的变化。此原始数据通过导入ArcMap并进行比电导率测量值的插值，以生成土壤电导率的二维地图，从而得到最佳利用。Hodges利用这些数据在她的流域中安装了生锈的钢铁型氧化还原指示器，以评估土壤氧化还原电位（首次部署，2015年10月）。日期范围注释：每两个月进行一次测量。
