Helicopter starting liftoff towing hoop for airborne electromagnetic (AEM) survey 2022

Detailed Description

Helicopter lifting off with geophysical equipment loop on ground below attached via slingload. 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).
