In 2008, Dr. Guy Meadows, then faculty in Atmospheric, Oceanic, and Space Sciences at the University of Michigan’s College of Engineering revisited the task of mapping the lake’s bathymetry, but this time with what many would consider a more sophisticated survey method. Using a small coastal survey vessel with on board precision acoustic depth sounding and differential Global Positioning System (GPS) instrumentation. Digitized by J. Tallant in ArcGIS.
