Publications

Publications during the past three decades using data from Emerald Lake, the Tokopah Valley and neighboring Sierran lakes and watersheds (n=159). The list includes 78 technical journal articles produced through funding from NASA, the California Air Resources Board, the National Park Service, the US Forest Service and University of California (1985-2001). There are 35 additional technical journal articles supported by funding from the National Science Foundation (2002-present). As of 2012, 23 M.S. and Ph.D theses have been completed using data from Emerald Lake and the Tokopah Valley. Twenty-three technical reports on the Emerald Lake Integrated Watershed Study and other associated research have been produced for State and Federal funding agencies.
