Data

This data release provides a variety of water quality benchmarks, compiled from multiple publications and attributed to the NHDPlus v2.1 hydrography, for the conterminous United States (CONUS) for use in integrated water availability studies for evaluating altered water conditions and potential ecological impacts. To avoid ambiguity in terms, for the purpose of this data release, we use...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the preliminary geologic map of the Greeley 1 degree x 2 degrees quadrangle, Colorado and Wyoming (Braddock and Cole, 1978). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in...

The 1966-2025 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes are roughly...

This data release contains metaproteomics data from subsurface methanogenic communities in an Antrim Shale (Michigan basin, MI) natural gas well. The subsurface microbial communities have interacted with produced waters that were exposed to ambient surficial conditions prior to injection of the produced waters into the well. These data are used in a related publication to understand...

This data release (https://doi.org/10.5066/P13JNYU2) contains neutron scattering intensities of a Niobrara Formation rock sample in the presence of pressurized perdeuterated methane, perdeuterated methane-methane, and perdeuterated methane-ethane mixtures at 60 degrees C. Also provided are the densities and scattering length densities for the various fluid mixtures and modeled accessible...

Recreational-grade sidescan sonar offers a rapid and cost-effective method for imaging benthic environments, and recent advances in image processing techniques have shown promise for producing automated, reproducible substrate maps from sonar imagery. To investigate potential suitability of substrates for lake sturgeon spawning habitat, the U.S. Geological Survey (USGS), in cooperation...
