Abstract: Spirit Lake was changed biologically, chemically and physically by the 1980 eruption of Mount St. Helens and the concurrent landslide that essentially buried the old lake and created a new one in its place. Recent changes to the surrounding watershed, spurred by ever-increasing regrowth of terrestrial vegetation, continue to alter the biogeochemistry of Spirit Lake. This talk will outline over a decade of work developing a hydrologic and nutrient model for the lake and discuss preliminary work to elucidate the ecological role of the floating logs in Spirit Lake.
Bio: Dr. Jim Gawel is Associate Professor of Environmental Chemistry and Engineering at the University of Washington Tacoma. Jim got his B.S. in Civil Engineering from Brown University with an emphasis in Environmental Problems and Planning, and his Ph.D. in Civil and Environmental Engineering from MIT. He has been teaching and doing research with undergraduates at UW Tacoma for 18 years. Jim is also the President of the Washington Lake Protection Association (WALPA), and has been working with WALPA to develop a state-wide volunteer lake monitoring program. In his spare time he teaches rock climbing for the Mountaineers.
