The Mississippi Alluvial Plain (MAP) Project contains several geologic units which act as important aquifers. We collected several sets of time-domain electromagnetic (TEM) data consisting of two higher-density surveys and six regional-scale transects. The higher density surveys were collected to compare and contrast to other geophysical data not included in this data release, such as airborne electromagnetic, magnetic resonance sounding, and towed time-domain electromagnetic surveys . The transects, which were collected over the span of three years, cross the MAP study area from east-to-west, with about 100 km line spacing, and cover an area of nearly 100,000 square-kilometer. Each transect spans a distance of...

This data release has three components for each of the eight stream lengths: 1) a geospatial dataset of the processed data; 2) tabular data of the processed waterborne resistivity profiling data and associated water-quality data; 3) tabular data of the raw waterborne resistivity data and associated water-quality data. In fresh water aquifers, the geoelectric resistivity of earth materials commonly has a positive correlation with hydraulic conductivity (Faye and Smith, 1994). Throughout 2017, continuous resistivity profiling data were collected, as a proxy for streambed hydraulic conductivity, along reaches of eight streams in the Mississippi Alluvial Plain of Mississippi, Arkansas, and Missouri. A total of...
