Detailed Description

Smiley face on front of electromagnetic (AEM) survey equipment at AEM survey in southwest Wisconsin 2022. 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).
