Determining Critical Loads of Nitrogen Deposition in the Pacific Northwest

Washington (Alpine Lake Wilderness & Mt. Rainer) Determining Critical Loads of Nitrogen Deposition in the Pacific Northwest Jasmine Saros August 2008 Paleolimnological studies in the Pacific Northwest have suggested possible acidification effects of nitrogen (N) and sulfur (S) deposition on alpine lakes in this region, but have been unable to generate a critical load at […]

Mapping Critical Loads of Atmospheric N and S Deposition in the Rocky Mountains

Rocky Mountains – 2007 & 2008 Mapping Critical Loads of Atmospheric N and S deposition in the Rocky Mountains Jasmine Saros, Heather Arnett Critical Loads are the amount of deposition of a given pollutant that an ecosystem can receive below which ecological effects are thought not to occur. In the proposed study, maps will be […]
