Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Fish target lengths of Silver Carp derived from Adaptive Resolution Imaging Sonar in backwater embayments of Kentucky Lake and Lake Barkley, Kentucky, 2022 February 18–23 Fish target lengths of Silver Carp derived from Adaptive Resolution Imaging Sonar in backwater embayments of Kentucky Lake and Lake Barkley, Kentucky, 2022 February 18–23
This dataset represents fish targets (presumed Silver Carp, Hypophthalmichthys molitrix) recorded using Adaptive Resolution Imaging Sonar (ARIS; Sound Metrics, Bellevue, WA) in five backwater embayments of Kentucky Lake and Lake Barkley, KY (2022 February). A surface-to-bottom block net was set across embayments in a “chevron” shape pointed upstream to guide fish movements downstream...
Water Quality Data from the Clinton River watershed near Detroit, MI Water Quality Data from the Clinton River watershed near Detroit, MI
This data release contains water quality data collected in the field during an in-situ mussel exposure. We collected dissolved oxygen, temperature, conductivity, and water depth data using a sensor silo to assess habitat conditions for a potential mussel restoration. Additionally, we collected particle count data to quantify food availability for mussels and water quality data...
Geospatial data for delineating and characterizing drainage basins in the Louisiana StreamStats study area Geospatial data for delineating and characterizing drainage basins in the Louisiana StreamStats study area
The U.S. Geological Survey (USGS), in cooperation with the Louisiana Department of Transportation, prepared hydrologically-conditioned geographic information systems (GIS) layers for use in the Louisiana StreamStats application. This data release contains vector and raster geospatial data used to delineate drainage basins and raster geospatial data for precipitation data used to...
Gravity and physical property data of the Blythe region, California and Arizona Gravity and physical property data of the Blythe region, California and Arizona
This data release presents point data associated with studies to understand the crustal structure of the Blythe region, where strands of the pre-Quaternary Eastern California Shear zone project across this region in California and Arizona. Data include principal fact information for new gravity measurements collected by the U.S. Geological Survey from 2020 to 2025, previously unpublished...
Polar Bear Microsatellite Data Southern Beaufort Sea 2010-2023 Polar Bear Microsatellite Data Southern Beaufort Sea 2010-2023
This data set provides polar bear microsatellite genotypes derived from twenty loci (CPH9, CXX20, CXX110, CXX173, G1A, G10B, G10C, G1D, G10H, G10J, G10L, G10M, G10P, G10U, G10X, MU50, MU51, MU59, MSUT2, 145P07). Blood, buccal swab, skin, and hair samples for microsatellite genetic analysis were collected from polar bears from the Southern Beaufort Sea between 1981 and 2023. Blood, buccal...
Fish eDNA metabarcoding from discarded USGS Cytiva GWV High-Capacity Capsule filters throughout the USA, 2022 Fish eDNA metabarcoding from discarded USGS Cytiva GWV High-Capacity Capsule filters throughout the USA, 2022
These metadata contain links to the original sequences (.fastq files) on GenBank. These data files contain the sample metadata, exact sequence variant (ESV) reads, and taxonomic identifications for the ESVs in each sample.
