Table 2 . Dr. Harry M. Jol, University of Wisconsin-Eau Claire, operated the ground penetrating radar for this project. The GPR was used to locate buried erosion scarps and delineate barrier stratigraphy throughout the littoral cell. Figure 13 . Ground Penetrating Radar in field operation.

GPR transects were generally run along roads or trails perpendicular to the shoreline. The spacing between profiles was approximately 2 to 5 km. Individual transect locations were selected by the project team. Selection was based on accessibility and abundance of potential interference features, such as power lines, underground pipes, roadside fences, etc. Figure 14 .
