Burton, B.L., Minsley, B.J., Bloss, B.R., Rigby, J.R., Kress, W.H., and Smith, B.D., 2019, Airborne electromagnetic, magnetic, and radiometric survey, Shellmound, Mississippi, March 2018 (ver. 2.0, March 2024): U.S. Geological Survey data release,


Airborne electromagnetic (AEM), magnetic, and radiometric data were acquired in late February to early March 2018 along 2,364 line-kilometers in the Shellmound, Mississippi study area. Data were acquired by CGG Canada Services, Ltd. with three different helicopter-borne sensors: the CGG Canada Services, Ltd. RESOLVE frequency-domain AEM instrument that is used to map subsurface geologic structure at depths up to 100 meters, depending on the subsurface resistivity; a Scintrex CS-3 cesium vapor magnetometer that detects changes in deep (hundreds of meters to kilometers) geologic structure based on variations in the magnetic properties of different formations; and a Radiation Solutions RS-500 spectrometer that detects the abundance of [...]

These data were collected to contribute high-resolution information about subsurface geologic structure that will be used to inform hydrologic models, water resource infrastructure studies, and local decision making concerning the Mississippi River Valley Alluvial aquifer.
