WGNHS alumnus Anna Fehling (now a hydrogeologist at the Wisconsin DNR) and WGNHS hydrogeologist David Hart received the 2022 John C. Frye Memorial Award in Environmental Geology for their report Potential Effects of Climate Change on Stream Temperature …
Sculpt Wisconsin’s aquifers using modeling clay
Looking for ways to teach geology to your students? We’ve developed some lesson plans to assist! In our newest lesson plan, students will use modeling clay to create a model of Wisconsin’s four main aquifers. …
UW Science Expeditions 2021: Create your own groundwater model
Learn firsthand about the connection between surface water and groundwater! Using a plastic shoebox, sand, and a turkey baster, participants will see how water enters and moves through an aquifer. This activity helps participants learn how water …
Aerial survey in northeast Wisconsin
In January 2021, northeastern Wisconsinites may notice a low-flying helicopter towing a large, hoop-shaped sensor. The helicopter’s sensor uses airborne electromagnetic (AEM) technology to gather data that will help scientists update depth to bedrock maps. …
Wisconsin’s Karst Aquifers
On February 19, 2020, WGNHS hydrogeologist Maureen Muldoon gave a talk for Wednesday Nite @ The Lab (WN@TL) entitled “Why Are Wisconsin’s Karst Aquifers So Susceptible to Groundwater Contamination?” This talk focused on the hydrogeology …
Streams of Data from Streams of Wisconsin
In this August 2019 talk for Wednesday Nite @ The Lab (WN@TL), WGNHS hydrogeologist Dave Hart explained how he and his team used canoes outfitted with an array of sensors to record vast amounts of …
Big Data from Small Streams (and Small Lakes—the 2018 Update)
Dave Hart, a WGNHS hydrogeologist, is designing and implementing a project that is challenging ideas about how much data is enough data. Dave collects data and uses models to understand Wisconsin’s water quantity and quality …
Groundwater, Wetlands, and Geology: The Invisible Links
Why do wetlands occur where they do? Where does their water come from? How are they connected to the groundwater systems around them? In this April 2018 talk for Wednesday Nite @ The Lab (WN@TL), …
Little Plover River Groundwater Model
In Wisconsin’s Central Sands, stretches of the Little Plover River have gone dry in past years. Some people have blamed high-capacity wells, while others cite changing land use, climate change, or natural weather patterns. To evaluate the …
