This dataset contains a combination of physiological and behavioral approaches for characterizing the response of bighead and silver carp to potentially attractive chemicals associated with sex pheromones identified in common carp. The dataset contains eight tables: 1) EOG responses from untreated and masculinized silver carp to prostaglandins, 2) mixture discrimination indices of the

This data set consists of physics-based Delft3D-FLOW and SWAN hydrodynamic models input files used to study the wave-induced 3D flow over spur-and-groove (SAG) formations. SAG are a common and impressive characteristic of coral reefs. They are composed of a series of submerged shore-normal coral ridges (spurs) separated by shore-normal patches of sediment (grooves) on the fore reef of...

This U.S. Geological Survey data release consists of a polygon geospatial dataset representing estimated flood-inundation areas in Grapevine Canyon near Scotty's Castle, Death Valley National Park, and the data acquired and processed to support the delineation of those areas. Supporting datasets include topographic survey data collected by global navigation satellite system (GNSS) and...

Groundwater residence times and flow path lengths were simulated for two major aquifers of the Mississippi embayment region using particle tracking (Pollock, 2012; Starn and Belitz, 2018) in a regional groundwater-flow model (Haugh and others, 2020). The Mississippi embayment physiographic region includes two principal aquifer systems: the surficial aquifer system, which is dominated by...

The U.S. Geological Survey (USGS), Colorado Division of Reclamation, Mining and Safety (DRMS), and Coal Creek Watershed Coalition (CCWC) working independently, have intermittently collected samples of surface- and groundwater and springs around Mount Emmons, near Crested Butte, Colorado. This data release is a compilation of the comprehensive inorganic chemical analyses conducted as a...

Apatite [Ca5(PO4)3F], titanite [CaTiSiO5], and rutile [TiO2] samples were collected by the U.S. Geological Survey (USGS) from the Coles Hill uranium deposit, Virginia. The samples (in the form of polished thin sections) were prepared and analyzed for direct age dating on a laser ablation inductively coupled plasma mass spectrometer (LA-ICPMS) system at the USGS in Denver, Colorado from...

Zircon (ZrSiO4) and cassiterite (SnO2) samples were collected by the U.S. Geological Survey (USGS) from the Yazov Granite, Transbaikalia region, Eastern Siberia, Russia. Samples (in the form of mounted loose grains) were prepared and analyzed for direct age dating on a laser ablation inductively coupled plasma mass spectrometer (LA?ICPMS) system at the USGS in Denver, Colorado from...

This data set is an amalgamation of twenty-nine original data sets, which represent amphibian surveys in the seven national parks comprising the North Coast and Cascades Network (NCCN) of the National Park Service. The data were collected from 1984-2005, and include the localities of 19 species of amphibians at various life stages, 18 native to the Pacific Northwest and one invasive...

These data are 30m by 30 m grids of the mean Standardized Precipitation-Evapotranspiration Index (SPEI) between 2001-2014 in the western United States. The SPEI index was developed by Sergio M. Vicente-Serrano and coauthors (https://spei.csic.es/index.html). Source evapotranspiration and precipitation data were generated by gridMET (http://www.climatologylab.org/gridmet.html).

The U.S. Geological Survey (USGS) monitors water surface flow reversals, commercial vessel traffic, and temperature and specific conductance in the U.S. Army Corps of Engineers Electric Dispersal Barrier System (EDBS) on the Chicago Sanitary and Ship Canal, Chicago, Illinois. These data are planned to be released on USGS Sciencebase annually. This data release is the summary of all the...

The Shady Rest thermal area (SRST) is characterized by elevated soil temperatures and CO2 emissions and associated vegetation kill. The site is located about 3 km northwest of the Casa Diablo geothermal power plant at Mammoth Lakes, California. The elevated soil temperatures and CO2 emissions are related to changes in the shallow hydrothermal system caused by geothermal fluid production...

This dataset contains environmental tracer data from surface water and groundwater samples collected by the U.S. Geological Survey in Redwell Basin, an alpine watershed in the Elk Mountains near the town of Crested Butte, Colorado. The basin is underlain by interbedded shale and sandstone that have been variably hydrothermally altered and silicified by local magmatic intrusions. Samples...
