Abstract
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).
