Daniel Engstrom

Daniel Engstrom is Director of the St. Croix Watershed Research Station — the environmental research center of the Science Museum of Minnesota — and Adjunct Professor in Geology and Geophysics and Water Resources Science at the University of Minnesota.  He received a Ph.D. in Ecology in 1983 at the University of Minnesota. His scientific interests include historic trends in deposition of atmospheric pollutants, global climate change in arid landscapes, and long-term human impacts on lakes and rivers. Especially relevant to this film series is work by Dr. Engstrom and his staff on the changing water quality of the upper Mississippi River. This research provides much of the scientific underpinning for ongoing efforts to substantially reduce nutrient and sediment runoff and restore ecological health to this impaired waterway.
