    • Airborne Electromagnetic (AEM) Survey in Southwest and Southeast Areas, Wisconsin, 2022

    Metadata Updated: July 6, 2024

    Airborne electromagnetic (AEM) and magnetic survey data were collected during March 2022 over a distance of 2,574.6 line kilometers in southeast and southwest Wisconsin. These data were collected in support of an effort to improve estimates of depth to bedrock through a collaborative project between the U.S. Geological Survey (USGS), Wisconsin Department of Agriculture, Trade, and Consumer Protection (DATCP), and Wisconsin Geological and Natural History Survey (WGNHS). Data were acquired by SkyTEM Canada Inc. with the SkyTEM 304M time-domain helicopter-borne electromagnetic system together with a Geometrics G822A cesium vapor magnetometer. The survey was acquired at a nominal flight height of 30 - 40 meters (m) above terrain. AEM data were inverted to produce models of electrical resistivity along flight paths, with typical depth of investigation up to about 400 m and 1 - 2 m near-surface resolution.
