The goal of this project is to understand how changing temperature, precipitation, and subsequent water table conditions alter the magnitude and direction of changes in sulfur and mercury release from peatlands to water to better predict future total mercury and methyl mercury levels in the Lake Superior watershed.
Why do this
Mercury in the Lake Superior Basin is a serious problem that affects the health and economy of the people of Minnesota. Headwater wetlands and peatlands are significant sources of mercury to surface waters, where environmental changes will possibly increase the mobility of mercury directly or through increased cycling rates of carbon and sulfur.
