This data release is companion to a manuscript entitled: "Long-term intermittent connection between the western Snake River Plain and Columbia Basin: a two-phased incision history of Hells Canyon". Here, we report the measured flow direction and compositions of clasts and detrital zircon U-Pb ages from samples collected from modern and ancestral rivers near the Lewiston Basin region. The...

The data tables in this product include concentrations, detection frequencies, benchmark exceedances, and trends of pesticides in riverine surface water samples. The data are a product of a national-scale assessment of the status and trends of 84 pesticides at 81 sites during water years 2013 - 2022 conducted by the U.S. Geological Survey (USGS) National Water Quality Program. Data were...

These data were compiled as part of an experimental study investigating alternative methods to dryland reclamation. The objective of our study was to evaluate the effects of conventional vs alternative approaches alone and in combination that included different seeding methods, seed mixes, and biological soil crust (biocrust) inoculation. These data were collected within the footprint of...

Radiometric data were collected at the Grand Junction Regional Airport radiometric calibration facility in March 2023 and August 2024. The facility consists of five ~9 by ~12 m (30 x 40 feet) concrete pads, each 18 in thick. Each pad provides sources of radioelements that are spatially homogeneous (see Ward, 1978). Three pads are dedicated K, Th, and U pads, each of which contains high...

Streamgaging weirs, like the ones used by the U.S. Geological Survey (USGS), play a critical role in providing accurate and stable streamflow data, but their presence can affect the passage of diadromous fish species such as river herring and American shad. In some situations, weirs existing in rivers and streams are no longer used because they were part of a farm irrigation system or...

Clear Lake is a 180 km2 freshwater lake located approximately 120 km northwest of Sacramento in the California Coast Range. The lake is a popular sport-fishing destination, however, there are fish consumption advisories associated with mercury (Hg) contamination for several species. The lake has three arms: a large open-water region to the northwest (Upper Arm), a smaller and narrower...

This dataset was compiled and analyzed to support the goals of quantifying groundwater contributions to Lake Huron and exploring the impacts of groundwater on Lake Huron processes in accordance with the Lake Huron Cooperative Science and Monitoring Initiative 2022 field season. This data release contains three child items that describe 1) the characterization of the Lake Huron Basin into

Seeds extracted from the gastrointestinal contents of Burmese pythons (Python bivittatus) and Black and White Tegu (Salvator merianae) lizards in South Florida were sorted and identified to genus or species. Seeds were then categorized as invasive (category I: history of negative impacts or category II: potential for negative impacts), native, non-native, threatened, endangered, and...

This data release includes the downscaled climate inputs from four Weather Generator Scenarios and hydrologic outputs using the Basin Characterization Model (BCM) version 8 (v8), described in Flint and others (2021a), with a 270 by 270-meter spatial resolution at a monthly time steps from water years 1916 to 2018 for California. Weather Generator scenarios defined as: BaseW = baseline...

The IntELiMon team releases Terrestrial Laser Scanner (TLS) derived datasets via the project's viewer daily. The datasets include multiple types of information related to each acquisition, including 3D point clouds, field observations, and surface and canopy fuel metrics in csv format. CSDGM FGDC XML metadata are included as a static accompanying file along with the dynamic datasets...

This dataset contains geospatial data compiled and generated to support supervised land cover classification and habitat monitoring across nine Wildlife Management Areas (WMAs) in Alabama. The dataset integrates Landsat 9 surface reflectance imagery acquired between May and July 2024, the 2021 National Land Cover Database (NLCD), NLCD-derived Tree Canopy Cover (TCC), a stacked predictor...

This dataset consists of three tables containing sample information and uranium-lead (U-Pb) isotopic data and U-Pb ages measured in zircon collected from igneous rocks in Alaska. The samples were collected between 2019 and 2023 and analyzed by laser ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) by GeoSep Services. The dataset includes 412 analyses across 13 samples...
