Geophysical equipment loop with sensor from SKYTEM for electromagnetic (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.

This is a small inset drawing of a truck traveling a haul road from a mine site.  It is a southwestern landscape, and depicts dust kicked from the road and becoming airborne over the surrounding vegetation and landscape.

This is a loosely drawn illustration of two hikers on the trail. It was drawn for the final page of a fact sheet and intended for text overlay. The text primarily indicates avenues of further study and next steps of the project.

Green Lake is the deepest natural lake in Wisconsin. The drawing relates the water-quality response of Green Lake, with emphasis on the Metalimnetic Oxygen Minima, to total phosphorus loading from its watershed. The drawing depicts data collection, analysis, modeling, and real-time monitoring.
