All Data

This data release includes Al-26/Be-10 cosmogenic nuclide concentrations and burial isochron ages for three locations in central Colorado, USA, with preferred burial ages ranging from ~2 Ma to 600 ka, that provide constraints on geologic mapping and chronostratigraphic correlations of Pleistocene Colorado Rocky Mountain (CRM)-Great Plains deposits. This new dataset helps to validate...

This dataset contains the data from laboratory and field testing of protocols to measure gas fluxes through mass flow meters attached to rigid chambers sealed to the ground. These tests demonstrate the quality of the ground seal and weather conditions around the chamber are critical for the quality of the data obtained from the technique. This measurement approach is useful for...

This dataset contains methane emissions measurements, gas compositions, and methane carbon isotope geochemistry analysis results from orphan oil and gas wells in the Kevin-Sunburst Dome in Toole County, Montana. Emissions measurements were taken between 2021 and 2023, and gas samples were collected in July, 2023.

The U.S. Geological Survey, Western Ecological Research Center collected sediment and accretion data at two marshes in San Francisco Bay, California over the course of 15 months, capturing a full hydrological year and two spring-summer transitions. Sediment traps were deployed monthly in triplicate along transects of increasing distance from sediment sources (i.e., channels) to capture...

The spatial data are results of USGS surveys for Least Bell's Vireo (Vireo bellii pusillus) (LBVI) along the San Luis Rey River for selected years (1996, 1999-2001, 2003-2004, 2007). Data was used to determine abundance and distribution of vireos as part of long-term demographic studies.

This data release contains water quality data from discrete sonde profiles taken at 10 sites on Lake Koocanusa from 2019 through 2024. The profiles include measurements of water temperature, specific conductance, dissolved oxygen, pH, turbidity, and chlorophyll relative fluorescence as well as the depth of the sonde below the water surface. These data were collected as part of a water...

This data set contains toxicity data from short term 7-day chronic water-only bioassays to assess the effects pH on ammonia toxicity to survival and growth of a juvenile fatmucket mussel (Lampsilis siliquoidea). We conducted 4 concurrent exposures at nominal pHs of 7.0, 7.5, 8.0, and 8.5 with varying ranges of ammonia to capture effect concentrations. This data set has three tables: (1)...

We collected cattle GPS location data within three sites across the Great Basin ecoregion. We then coupled these data with multi-resolution remotely sensed vegetation, hydrology, and topographic data to develop a cattle resource selection surface across Nevada and northeastern California. This layer can support grazing management through targeted or rotational grazing by providing a...

This data release contains photographs and photomicrographs from drill cores and cuttings of pre-Middle Jurassic basement rocks that are buried beneath Coastal Plain sedimentary deposits in Florida. These samples provide rare insights into deeply buried rocks that have no surface exposures and no known exposed correlates. These images were acquired to support the characterization...

This data release reports the mineral abundances in samples of pre-Middle Jurassic basement rocks from twenty-nine (29) boreholes in Florida and southern Alabama. Mineral abundances are quantified from whole-rock powder X-ray diffraction (XRD) data and the Rietveld method and are reported in weight percent or, where present near the detection limit (~1 wt.% depending on mineral), as...

The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across western North America using Landsat imagery from 1985-2024. The RCMAP product suite consists of ten fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub...

This dataset includes geochemical, isotopic, and particle-size data for soil and sediment samples collected at approximately 500 sites in the Clear Lake drainage basin, Lake County, California, between November 2021 and December 2023. Data are also reported for ten soil samples collected during October 2018 soon after the Ranch Fire in the upper Scotts Creek watershed. Samples of lakebed...
