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.

Airborne geophysical surveys of the lower Mississippi Valley demonstrate system-scale mapping of subsurface architecture
The Mississippi Alluvial Plain hosts one of the most prolific shallow aquifer systems in the United States but is experiencing chronic groundwater decline. The Reelfoot rift and New Madrid seismic zone underlie the region and represent an important and poorly understood seismic hazard. Despite its societal and economic importance, the shallow subsurface architecture has not been mapped with the sp - Connect
