Geologic mapping is fundamentally discovery research: it provides baseline data for varied basic research and applied problems. The mapper always uncovers new and interesting questions. Over the past 5 years, surficial mapping in the lower Wabash Valley has contributed to the existing geologic framework with insights on neotectonics, Quaternary history, and floodplain evolution. There are opportunities for undergraduate and graduate students to map 7.5’ quadrangles or portions of quadrangles, that may constitute all of a Senior Thesis or part of a graduate research project. The work involves field investigations, laboratory study, and GIS analysis. Competitive funding through the USGS EDMAP program (http://ncgmp.usgs.gov/about/edmap.html) is sought in the fall, with fieldwork beginning in late spring; deliverables are due one year from the start date.

Passive seismic method uses vibrations generated by waves crashing on distant coasts as well as passing traffic to characterize the subsurface. For Quaternary studies, sounding with PS has been demonstrated as a method for quickly mapping bedrock topography in a variety of terrains and bedrock lithologies. We have a Tromino device that we would like to use to test and supplement a draft bedrock topography map for the lower Wabash Valley and surroundings. I envision a project suitable for a Senior Thesis/Independent Study that could involve both theoretical and practical aspects of the method. A two-semester project would likely be best, although a particular well-prepared and motivated student might be able to do it in one. The project would involve 5-10 days of fieldwork, depending in part on the student’s level of interest. The product would include a report and map that would be presented at the North-Central GSA meeting in Champaign 2016. The project could even be a foray into Master’s-level research that could begin the following summer. Seed funding is available, but we would likely want to search for more.
