DUGG: Dune Undergraduate Geomorphology and Geochronology

CSS to Superimpose Title

Since the last Ice Age, shoreline elevations of the Great Lakes were influenced by post-glacial isostatic rebound, changing outlet elevation, and climate change.  The Dune Undergraduate Geomorphology and Geochronology (DUGG) project focuses on how these processes influence eolian systems along the Wisconsin shoreline of Lake Michigan.  Unlike the eastern side of the Lake, large dunes are rare along the Wisconsin shoreline except for a few areas of the Door Peninsula. Students from across the country work with Dr. Rawling and colleagues from the University of Nebraska-Lincoln and the UW-Extension Wisconsin Geological and Natural History Survey for eight weeks during the summer.  Methods employed for this student-driven undergraduate research includes ground penetrating radar, optical dating and laser diffraction particle-size analysis. The DUGG project is funded by National Science Foundation Research Experience for Undergraduate program.
