Airborne Electromagnetic (AEM) Survey Inventory

Metadata Updated: October 30, 2025

The U.S. Geological Survey (USGS) has been engaged in airborne electromagnetics (AEM) since the 1970s, playing a role in the development of early acquisition systems, developing calibration methods, refining standards for data acquisition, improving data processing, modeling, and interpretation methods, and expanding the range of AEM applications. However, USGS AEM survey visibility and data accessibility has not advanced as rapidly as our use of the technique. This data release catalogs AEM surveys in the United States that have contributed to studies under USGS programs including Water, Geologic Mapping, Minerals, Energy, Environmental Health, Ecosystems, Hazards, and Climate. This dataset contains locations for known and inventoried surveys, shows the footprints of the survey area, and summarizes basic survey specifications and publication status. It deviates from the national airborne geophysical survey inventory (https://mrdata.usgs.gov/airborne/): the AEM-specific data release catalogs completed and contracted AEM surveys including those that have not been published to date. This release also includes an indicator of activity status with the intent of improving utility and leading to regular updates; inactive (studies utilizing these data are complete), active (data are currently being used as part of on-going USGS research), and planned (acquisition is currently in progress at publication date).
