Summary

Great Salt Lake (GSL) is a designated Site of Hemispheric Importance for migratory birds by the Western Hemisphere Shorebird Reserve Network. Elevated mercury (Hg) and methylmercury (MeHg) levels related to current inputs and past industrial contamination pose a potential threat to GSL biota, in addition to waterfowl hunters that utilize GSL and surrounding wetland areas. Sediments, invertebrates (brine shrimp, brine flies, and spiders), and waterfowl (northern shoveler and cinnamon teal) were targeted within these studies to determine relative source contributions of Hg and trace elements to the GSL system, determine which sources of mercury are actively bioaccumulating in GSL food webs, assess controls on mercury cycling within the [...]

Purpose

Sediments, waters, and biological samples were collected to examine mercury (Hg) and trace element sources and cycling within the Great Salt Lake (GSL) in UT. This data set was prepared to assess changes in relative contributions of Hg/metal sources to GSL over time, study drivers of Hg bioaccumulation within the system, and assess risk to waterfowl. These data can help inform current management strategies for GSL waterbird habitat.
