The use of Continuous Resistivity Profiling to Evaluate Geomorphologic Controls on Aquifer Recharge in the Mississippi Alluvial Plain from Money to Steiner, Mississippi, August 2016 to November 2016

This content represents a map displaying the vector data corresponding to the processed datasets for the capacitively coupled resistivity profiling surveys across the Mississippi Alluvial Plain. The .sd file is an ESRI service definition file containing all the data (compatible for use in ESRI ArcDesktop). This file contains the shapefile representing data from the entire study area. These are all displayed in the map service definition. Users can also download the .sd file and extract the content (using 7zip, WinZip, or similar products) on their local machine to obtain the stand-alone shapefile. In cooperation with more than 10 local, State, and Federal stakeholders, the United States Geological Survey (USGS) is studying the aquifer systems in and near the Mississippi River alluvial plain (https://www2.usgs.gov/water/lowermississippigulf/map/index.html). This data release consists of continuous resistivity profiling (CRP) data collected by the USGS to characterize the electrical properties of geomorphological features in the part of the Mississippi River alluvial plain from Money, Miss. to Steiner, Miss. A total of 68 kilometers of multiple CRP profiles were obtained. The CRP data were collected by using the Ohmmapper TR-5 system (Geometrics, Inc., 2016) to determine if different geomorphological features in the study could be identified. Drilling logs from nearby boreholes were used to confirm if apparent changes in lithology correlated positively with apparent changes in resistivity profiles.
