High resolution aeromagnetic survey used to infer the locations of igneous rock bodies in the area, which are provided in GIS data files

Info
Airborne electromagnetic and magnetic survey data, Big Sioux aquifer, October 2015, Sioux Falls, South Dakota

Airborne electromagnetic (AEM) and magnetic survey data collected in 2015 along 769 line-kilometers including raw and processed AEM and magnetic data, processed AEM resistivity-depth inversions. Data are provided in CSV format.

Info
Helicopter electromagnetic and magnetic survey data and maps, Seco Creek area, Medina and Uvalde Counties, Texas

Airborne geophysical data and a summary of the hydrologic application.

Info
Helicopter electromagnetic and magnetic geophysical survey data, Hunton anticline, south-central Oklahoma

Flight line data, grids, and inversions for these surveys are intended to help understand shallow groundwater and develop groundwater resource plans for the aquifer.
