Application of mercury stable isotopes to examine sources and hydrologic factors impacting mercury bioaccumulation and cycling in invertebrates of a model saline lake Application of mercury stable isotopes to examine sources and hydrologic factors impacting mercury bioaccumulation and cycling in invertebrates of a model saline lake

Invertebrates, such as brine shrimp and brine flies, are key prey items for millions of resident and migratory birds that utilize saline lakes such as Great Salt Lake (GSL). Elevated methylmercury (MeHg) in invertebrate and waterfowl species of GSL has been assumed to be linked to elevated MeHg in GSL’s anoxic Deep Brine Layer (DBL) where aqueous concentrations can exceed 30 ng/L. Here...

Estimation of baseflow and flooding characteristics for East Canyon Creek, Summit and Morgan Counties, Utah Estimation of baseflow and flooding characteristics for East Canyon Creek, Summit and Morgan Counties, Utah

An improved understanding of hydrologic responses to changing climatic conditions is needed to better inform water management practices. East Canyon Creek, a perennial, snowmelt-dominated stream in the Wasatch Mountains of northern Utah, is subjected to increasing development and demands on water in the Snyderville Basin and adjacent areas. In this study, streamflow and specific...

Using mercury and lead stable isotopes to assess mercury, lead, and trace metal source contributions to Great Salt Lake, Utah, USA Using mercury and lead stable isotopes to assess mercury, lead, and trace metal source contributions to Great Salt Lake, Utah, USA

Great Salt Lake is a critical habitat for migratory birds that is threatened by elevated metal concentrations, including mercury (Hg) and lead (Pb), and is subject to severe hydrologic changes, such as declining lake level. When assessing metal profiles recorded in Great Salt Lake sediment, a large data gap exists regarding the sources of metals within the system, which is complicated by...

Prey Availability

Migratory wildlife need to balance the benefits of migration and reproduction with the physiological costs. This is particularly challenging in dynamic environments like wetlands, where food levels can vary greatly from year to year. For shorebirds in the Great Basin region, saline or terminal lakes provide essential habitats during their annual life cycle. To understand how changes in hydrology...

Coproduced Science Linking Environmental and Public-Health Data to Evaluate Drinking Water Arsenic Exposure on Birth Outcomes

U.S. Geological Survey (USGS) scientists teamed up with public-health epidemiologists to probe for associations between arsenic in drinking water and human-birth outcomes. They reported a modest inverse relation between birth weight and arsenic exposure. Findings indicate that future research efforts using individual-level exposure data such as measured arsenic concentrations in tap water could...
