Data

The vernal pool fairy shrimp, Branchinecta lynchi, (Branchiopoda; Anostraca) and other fairy shrimp species have been listed as threatened or endangered under the United States Endangered Species Act (ESA). There is little information about the sensitivity of Branchinecta spp. to toxic effects of contaminants, making it difficult to determine whether they are adequately protected by water quality

Data set contains depth and velocity grids generated from hydrodynamic model (SRH-2D) simulations run for a range of discharges. Date range corresponds to month(s) that bathymetric survey was performed. Three study reaches were considered in this analysis: the Fairview reach of the Yellowstone River, MT, the Miami and Lisbon-Jameson reaches of the Lower Missouir River. Data and application are des

USGS is currently conducting biological surveys associated with uranium mines on federal lands in Arizona. These surveys include determining the composition of the local amphibian community at Canyon, Arizona 1, and Pinenut mines near the Grand Canyon. To aid in determining the amphibian species present at each mine site, we used acoustic monitoring recorded with a SM3Song Meter (Wildlife Acoustic

This dataset includes microsomal EROD data from a liver sample assay. The samples are from several fish species that live in the Salt and Gila rivers, Arizona at sites that are being assessed for PBDE contamination. The data was created in September and October 2016.

The risks to wildlife and humans from uranium (U) mining to the Grand Canyon watershed are largely unknown. In addition to U, other co-occurring ore constituents contribute to risks to biological receptors depending on their toxicological profiles. This data was collected to characterize the pre-mining concentrations of total arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), mercury (Hg), nicke

Between the years 2000 and 2016, scientists and technicians from the U.S. Geological Survey (USGS) Columbia Environmental Research Center (CERC) have collected over 400 field-days worth of acoustic Doppler current profiler (ADCP) measurements on the Missouri and Yellowstone Rivers, primarily for the purposes of assessing physical aquatic habitat for the pallid sturgeon. Scientists and technicians

Invasive crayfish are known to displace native crayfish species, alter aquatic habitat and community structure and function, and are serious pests for fish hatcheries. White River Crawfish (WRC; Procambarus acutus) were inadvertently introduced to a warm-water fish hatchery in Missouri, USA, possibly in an incoming fish shipment. We evaluated the use of chemical control for crayfish to ensure inco

The health of soils along roadways is critical for maximizing habitat quality and minimizing negative ecological effects of roads. Adjacent to unpaved roads, soil chemistry may be altered by the deposition of dust, as well as by road treatment with dust suppressants or soil stabilizer products. If present in roadside soils, these product residues may be available to plants, terrestrial invertebrat

This is a polygon coverage of sand deposits from the 2011 Missouri River flood. The polygon coverages were compiled from classification of 26 multispectral SPOT (Systme Pour lObservation de la Terre) 4 and 5 satellite images colleted during October and November, 2011. The dataset covers 1,298 km of the Missouri River valley bottom from Gavins Point Dam in South Dakota to the confluence with the Mi
