Summary

This data release contains electrical resistivity tomography (ERT) and passive seismic data collected east of Ellsworth Air Force Base, South Dakota, from April to September 2021. The data accompanies a USGS scientific investigations map from Medler (2022). The U.S. Geological Survey, in cooperation with the U.S. Air Force Civil Engineer Center, used surface geophysical methods to delineate the top of the Cretaceous Pierre Shale along survey transects in selected areas east of Ellsworth Air Force Base, South Dakota. In 2021, the U.S. Geological Survey performed passive seismic and 2D electrical resistivity tomography (ERT) surveys along 21 co-located survey transects east of Ellsworth Air Force Base. Passive seismic data were analyzed [...]

Purpose

The purpose of this study was to delineate the Cretaceous Pierre Shale using two complementary geophysical surveys by the USGS from April to September 2021 east of Ellsworth Air Force Base, South Dakota. Electrical resistivity tomography (ERT) and horizontal-to-vertical spectral ratio (HVSR) surveys were co-located for direct comparison and to compliment the delineation of the Pierre Shale along profiles in selected areas. The purpose of delineating the Pierre Shale was to improve the understanding of groundwater flow in unconsolidated deposits overlying the Pierre Shale within and near EAFB.
