Paul F Schuster

Paul's research and monitoring work has included many national-scale studies such as acid rain studies, Grand Canyon flood reconstruction studies, paleoclimate and paleoenvironmental pollution studies on the glaciers of Wyoming, aquatic cycling of mercury and climate change studies as far south as the Florida Everglades and as far north as the Yukon River Basin, Alaska. Paul has been the laboratory supervisor all of these studies, including the Water, Energy, and Biogeochemical Budget (WEBB) Program. Paul encourages interactions among scientists and non scientists of diverse backgrounds and disciplines.
