Shallow soil characteristics were mapped near Shellmound, Mississippi, using the DualEM 421 electromagnetic sensor in October 2018. Data were acquired by towing the DualEM sensor on a wheeled cart behind an ATV, with the sensor at a height of 0.432 meters (m) above the ground surface. Approximately 175 line-kilometers of data were acquired over an area of nearly four square kilometers, with 25 m separation between survey lines. Data were manually edited for noise sources such as powerlines or other buried structures, and averaged to regular output soundings every 5 m along survey lines. This data release contains the processed data that have been averaged and culled to produce final resistivity models. Digital data...

The final inverted resistivity models within the “Airborne electromagnetic surveys of the Mississippi Alluvial Plain and Chicot Aquifer System, March 2018 and May - August 2021: Resistivity Models” child item are broken up according to the three main objectives of these surveys: River surveys along the thalweg of major rivers with the MAP and the Chicot Aquifer extents; Levee surveys along the Mississippi and Arkansas rivers from Cairo, IL to Baton Rouge, LA and northwest from the confluence of the Mississippi and Arkansas rivers to Pine Bluff, AR; and gridded products mainly focused on gravel bars within the Mississippi River from Helena, MS to the confluence with the Arkansas River. The data in this child item...

The processed data were inverted to recover models of electrical resistivity structure as a function of depth at each sounding location...
