All Data

This data release contains groundwater-quality data for three parameters of interest (arsenic, manganese, and pH) and well information for sample sites for aquifers in the conterminous U.S. Water-quality data and well information were derived from a dataset compiled from three sources: the U.S. Geological Survey (USGS) National Water Information System (NWIS), the U.S. Environmental...

This data release compiles the X-ray diffraction and electron microscopy analyses of drill core samples collected by the U.S. Geological Survey that were selected to typify the uranium-copper ore bodies of the Canyon deposit. The deposit is hosted by a solution-collapse breccia pipe, in which mineralization exists from about 650 to 2,100 ft (200 to 640 m) below the surface (Mathisen and...

This dataset includes results of the Trend Departure Index (TDI) for 139 sites in the RESTORE trend analysis study and approximately 9,200 HUC12 pour points in the streamflow alteration study. Data from the 139 sites in the trend analysis were compared against reference site data from the GAGES II dataset (Falcone and others, 2010) and were used to calculate the departure from reference...

This data release presents geochemical analyses of silicate melt inclusions, host quartz phenocrysts, and biotite phenocrysts in samples collected by the U.S. Geological Survey (USGS) from mid-Cenozoic rhyolitic rocks from northern Nevada. Igneous intrusions and volcanic rocks in this study encompass nineteen rhyolitic samples from five magmatic centers across northeastern Nevada...

Hydroacoustic estimates of fish density are used for fisheries management in central Lake Erie. Hydroacoustic data were collected along up to four cross-lake transects in central Lake Erie July 2010 through July 2019. Software-generated raw variables used for calculating estimates of hydroacoustic fish densities are presented here.

A three-dimensional, groundwater-flow model developed by Halford and Jackson (https://doi.org/10.3133/pp1863) was used to simulate effects of future (2020—2120) groundwater pumping on water levels and natural discharges in the Alkali Flat–Furnace Creek Ranch (AFFCR), Ash Meadows, Pahute Mesa–Oasis Valley (PMOV), and Pahrump to Death Valley South (PDVS) groundwater basins, southern Nevada...

Sediment Data: These data include (1) physical suspended-sediment sample data including suspended silt and clay concentration, suspended-sand concentration, and suspended-sand grain size distribution, (2) bed-sediment sample data with complete grain size analyses, and (3) 15-minute acoustical sediment data measured using a multifrequency array (1MHz and 2MHz) of sidelooking acoustic...

This data release includes 2 child items with tracking data for Northern Fulmars, a seabird species that breeds throughout northern ocean regions and spends the winter at-sea in the northern hemisphere. Child Item 1: "Argos Satellite Tracking Data for Northern Fulmars (Fulmarus glacialis) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child

This data release includes 2 child items with tracking data for Tufted Puffins, a seabird species that is found only in coastal and offshore areas of the North Pacific Ocean. Child Item 1: "Argos Satellite Tracking Data for Tufted Puffins (Fratercula cirrhata) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking...

The Subaerial Barrier Sediment Partitioning (SBSP) model is a framework to simulate the morphological development of an idealized barrier coast in the cross-shore domain. The model code, built in MATLAB, consists of two scripts which must reside within the same folder when executed. The first, SBSP_InputControl.m, contains the user-defined input variables to run the simulation. The...

Native trout in the West suffer a high degree of vulnerability, as highlighted by cutthroat trout, a group of 14 subspecies, most of which have been petitioned for listing under the Endangered Species Act (ESA). In the Southern Rocky Mountains, greenback cutthroat trout (Oncorhynchus clarkii stomias; GBCT) are listed as threatened under the ESA, and few populations remain, in part...

Thermal data collected from iButton temperature loggers implanted into research animals (Argentine giant tegus) and in their surrounding environment. Tegus undergo winter dormancy (hibernation) to cope with colder temperatures, and we studied the thermal habits of wild tegus within their invaded range in southern Florida, USA. We used radiotelemetry and trail cameras to verify dates of...
