Airborne geophysical surveys were acquired in March 2018 and May 25 through August 7, 2021 using a helicopter-based platform. These surveys were collected along 10,706 line-kilometers (line-km) within selected areas of the Mississippi Alluvial Plain (MAP) and the Chicot Aquifer System in the southeastern United States. The airborne geophysical surveys include electromagnetic, magnetic, and radiometric sensor data collected in rivers and levees throughout the two areas to evaluate groundwater and surface-water interaction, riverine ecosystems, and infrastructure. This data release contains three child items that provide: Minimally processed (raw) data supplied by the airborne contractor (Xcalibur Multiphysics)...

This data release contains machine-readable files accompanying the study “Quaternary Reelfoot fault deformation in the Obion River valley, Tennessee, USA" published by Delano et al. (2021) in Tectonics. The data release includes grain size analyses from three auger sites (TableS1_WilsonLoop_grainsize.txt, TableS2_Lanesferry_grainsize.txt, TableS3_BiggsFarm_grainsize.txt) and unit descriptions from three auger sites and a modern analog (TableS4_modern_floodplain_unit_desc.csv, TableS5_Wilson_Loop_unit_desc.csv, TableS6_Lanesferry_Road_unit_desc.csv, TableS7_Biggs_Farm_unit_desc.csv). A readme file (readme.txt) provides details for each file. Delano, J.E., Briggs, R.W., Thompson Jobe, J., Gold, R.D., and Engelhart,...
