Dale M Robertson
Dale Robertson is a Research Hydrologist with the Upper Midwest Water Science Center.
Dale is an Adjunct Professor at the University of Wisconsin-Green Bay, Michigan Technological University, and University of Toledo, and a Honorary Fellow with the Center for Limnology at the University of Wisconsin-Madison. His current research with the USGS deals with modeling eutrophication and mixing in lakes, estimating loads and concentrations of nutrients and sediment in streams over large geographic areas, such as the Great Lakes and Mississippi River Basins, developing nutrient criteria for streams and rivers, and examining the effects of climate change on the physical dynamics, ice cover, and productivity of lakes.
