Summary

This data release consists of three different types of geoelectric data measured along three curvilinear profiles during two separate geophysical surveys completed on July 9, 2017 and January 9, 2018. The datasets include three self-potential (SP) profiles, two spatially-coincident electric contact-resistance (CR) profiles, and two spatially-coincident electric resistance tomography (ERT) tomograms. All profiles were oriented in a northeast-southwest alignment along 650 meters of a natural berm parallel to a surface-water reservoir to the west and Hamilton Creek to the east, in Burnet County, Texas. The profiles along the berm began at latitude and longitude coordinates (30.716319o N, -98.229917o W) and terminated at latitude and longitude [...]

Purpose

The purpose of this work was to use non-invasive geophysical methods of self-potential, contact resistance, and electric resistance tomography to identify dissolution cavities and preferential groundwater seepage conduits in the Tanyard and Gorman Formations of the Ellenburger–San Saba aquifer and the San Saba Member of the Wilberns Formation.
