Annie L. Putman, Daniel K. Jones, Molly A. Blakowski, Destry N. DiViesti, Scott Hynek, Diego P. Fernandez, Danielle Mendoza
2022, GeoHealth (6)
The Salt Lake Valley, UT, USA, is proximal to the desiccating Great Salt Lake (GSL). Prior work has found that this lakebed/playa contributes metals-laden dust to snow in the Wasatch and Uinta Mountains. Dust and industrial particulate pollution are also delivered to communities along the Wasatch Front,...

Roy Sando, Kristin L. Jaeger, William H. Farmer, Theodore B. Barnhart, Ryan R. McShane, Toby L. Welborn, Kendra E. Kaiser, Konrad Hafen, Kyle W. Blasch, Benjamin C. York, Alden Shallcross
2022, Journal of Hydrology X (17)
The presence of year-round surface water in streams (i.e., streamflow permanence) is an important factor for identifying aquatic habitat availability, determining the regulatory status of streams, managing land use change, allocating water resources, and designing scientific studies. However, accurate, high resolution, and dynamic prediction of streamflow permanence that accounts for...
A multiscale approach for monitoring groundwater discharge to headwater streams by the U.S. Geological Survey Next Generation Water Observing System Program—An example from the Neversink Reservoir watershed, New York
Martin A. Briggs, Christopher L. Gazoorian, Daniel H. Doctor, Douglas A. Burns
2022, Fact Sheet 2022-3077
Groundwater-stream connectivity across mountain watersheds is critical for supporting streamflow during dry times and keeping streams cool during warm times, yet U.S. Geological Survey (USGS) stream measurements are often sparse in headwaters. Starting in 2019, the USGS Next Generation Water Observing System Program developed a multiscale methods and technology testbed...

Allen Evans, Quinn Payton, Nathan V Banet, Bradley M. Cramer, Caylen Kelsey, David A. Hewitt
2022, North American Journal of Fisheries Management (42) 1561-1574
Previous research suggests that predation by piscivorous colonial waterbirds may negatively influence the survival of Lost River Suckers (LRS) Deltistes luxatus and Shortnose Suckers (SNS) Chasmistes brevirostris in the Upper Klamath Basin (UKB), USA. However, estimates of predation from past studies, which were based on suckers with PIT tags, represent...

Michelle M. Irizarry-Ortiz, John F. Stamm, Carolina Maran, Jayantha Obeysekera
2022, Scientific Investigations Report 2022-5093
Planning stormwater projects requires estimates of current and future extreme precipitation depths for events with specified return periods and durations. In this study, precipitation data from four downscaled climate datasets are used to determine changes in precipitation depth-duration-frequency curves from the period 1966–2005 to the period 2050–89 primarily on the...
A case of Te-rich low-sulfidation epithermal Au-Ag deposits in a calc-alkaline magmatic arc, NE China
Shen Gao, Albert H. Hofstra, K. Qin, H. Xue
2022, Ore Geology Reviews (151)
Tellurium-bearing low-sulfidation epithermal Au-Ag deposits are significant producers of gold, silver, and potentially strategic elements if mineral processing methods are optimized for recovery. Although these deposits are generally related to alkaline magmatism, our study documents an unusual occurrence of Te-rich low-sulfidation epithermal systems in the North Heilongjiang Belt in...
Rapid and gradual permafrost thaw: A tale of two sites
Burke J. Minsley, Neal Pastick, Stephanie R. James, Dana R.N. Brown, Bruce K. Wylie, Mason A. Kass, Vladimir E. Romanovsky
2022, Geophysical Research Letters (49)
Warming temperatures and increasing disturbance by wildfire and extreme weather events is driving permafrost change across northern latitudes. The state of permafrost varies widely in space and time, depending on landscape, climate, hydrologic, and ecological factors. Despite its importance, few approaches commonly measure and monitor the changes...
Postfire debris flow hazards—Tips to keep you safe
Steven Sobieszczyk, Jason W. Kean
2022, Fact Sheet 2022-3078
Often referred to as “mudflows,” debris flows are a type of landslide made up of a rapidly moving mixture of dirt, rocks, trees, and water (and sometimes ash) that start on a hillside and travel downvalley. They can easily overflow channels and severely damage houses, vehicles, or other structures. Areas...

Sara Hutton, Samreen Siddiqui, Emily Pedersen, Christopher Markgraf, Amelie Segarra, Michelle L. Hladik, Richard E Connon, Susanne M. Brander
2022, Science of the Total Environment (857)
Pyrethroids, a class of commonly used insecticides, are frequently detected in aquatic environments, including estuaries. The influence that salinity has on organism physiology and the partitioning of hydrophobic chemicals, such as pyrethroids, has driven interest in how toxicity changes in saltwater compared to freshwater. Early life exposures in fish to...

Anna Potysz, Lukasz J. Binkowski, Jakub Kierczak, Barnett A. Rattner
2022, Science of the Total Environment (857)
In many countries the use of lead-based ammunition is prevalent, and results in exposure and poisoning of waterfowl and other species of birds. In waterfowl hunting areas large quantities of spent shot may be deposited in wetland and terrestrial habitats. These pellets can undergo transformation, which are influenced by various...
