Lowflying helicopter with geophysical equipment loop deployed below it via slingload. 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.

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).
