This data release consists of historical borehole geophysical data collected by various entities and digitally recreated by the U.S. Geological Survey to characterize the physical properties of the subsurface in the Mississippi Alluvial Plain from Louisiana to Missouri. The geophysical log data were collected by different Federal, state, and local agencies throughout the area, and were obtained from two sources: Hart and Clark (2008) or the Mississippi Department of Environmental Quality (MDEQ) website. The log data generally consisted of either scanned .jpg or .tif images of the original log. The data was digitized using Neurolog v.2015.12 (NeuraLog.com). This process involves tracing each log over a user-defined grid area, and can be exported in various formats such as .las (log ascii standard) file that can be read into other software packages.

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
