Airborne electromagnetic (AEM) survey hoop on snowy ground with technician preparing for liftoff

Detailed Description

Geophysical equipment loop for airborne electromagnetic (AEM) survey on ground prior to liftoff. Technician on ground for scale. In March 2022, a helicopter carried an airborne electromagnetic induction sensor over parts of southeast and southwest Wisconsin as part of a USGS study to map the aquifers in the region. The data will be used to inform models of water availability and quality in the region that can be used by resource managers and policy makers. This photo shows the equipment being deployed from a low-flying helicopter operated by specially trained pilots. The survey is in partnership with Wisconsin Geological and Natural History Survey (WGNHS), Natural Resources Conservation Service (NRCS) and Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP).
