GEOCHEMICAL EVIDENCE OF ANTHROPOGENIC IMPACTS ON SWIFTCURRENT LAKE, GLACIER NATIONAL PARK, MT

摘要

2010 marked the centennial anniversary of the commemoration of Glacier National Park, and since its dedication, the region has experienced increasingly severe effects of anthropogenic disturbance. As atmospheric CO_2 concentrations continue to rise, most-if not all-of the Park's remaining glaciers are projected to disappear by 2030 (Hall and Fagre, 2003), so it has become more important than ever to understand how humans impact this environment. The sediments preserved in the Park's glacially-fed alpine lakes reflect important climatic and geochemical changes in response to anthropogenic influence (MacGregor et al., 2011).
