Summary

Airborne magnetic gradiometry data along the tie and flight lines are provided here in CSV (Comma Separated Value) format along with a GeoTIFF grid of the total magnetic intensity (TMI) in nanoTeslas. Along with the data provided on this child page, a report in PDF format by the airborne contractor that describes the technical details of the data collection, reduction and processing procedures and a zip file that contains the contractor's deliverable products (Geosoft databases and grids) for the magnetic and radiometric survey is available on the parent page (https://doi.org/10.5066/P9TK8KMM).

Purpose

The airborne magnetic and radiometric survey was designed to augment and connect several previous USGS geophysical surveys in order to provide a continuous representation of the magnetic and radiometric fields from southeast Missouri to western Kentucky. These data will be used to better understand the surface and concealed geologic framework.
