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.

Repeat microgravity data from Anza Valley, California, 2019-2023
This dataset represents the network-adjusted results of relative- and absolute-gravity surveys performed from 2019 to 2023 in and near Anza Valley, California. Relative surveys were done using a Zero Length Spring, Inc. Burris relative-gravity meter. Absolute-gravity surveys were done using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. The effect of solid Earth tides and ocean...
Winter cover crop biomass and Nitrogen content in on-farm sampling, with corresponding Sentinel-2 band values and spectral indices, Maryland, USA, 2019-2023
This data release contains in situ winter cover crop biomass sampling data collected from fields located on the Delmarva Peninsula (Talbot, Queen Anne’s and Caroline County, Maryland, USA) and at the USDA-ARS Beltsville Agricultural Research Center (BARC), Beltsville, Maryland, USA. Samples were collected during the winter cover crop growing season, between November and April, from 2019...
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...
Pygmy Rabbit capture locations in Rich county, Utah, 2006-2008
Capture locations for pygmy rabbits (Brachylagus idahoensis) in Rich County Utah. These records contain capture records for rabbits in 3 allotments in Rich County, Utah during 2006-2008. Basic morphological data were collected at the time of capture. Some rabbits recorded here are part of a telemetry study (https://doi.org/10.5066/P147ZKDU.).
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...
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
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
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...
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.
Quartz Valley Geologic Framework and Borehole Data
The Quartz Valley Geologic Framework uses geologic data gathered from previous publications (Mack, 1958) and airborne electromagnetic (AEM) surveys (California Department of Water Resources, 2024) in conjunction with the well log database presented in this data release to create an understanding of the extents and thicknesses of geologic units including channel alluvium, alluvium and...
Analysis data for reed canarygrass (Phalaris arundinacea) niche modeling in Upper Mississippi River floodplain forest understories
This dataset contains the information used to perform ecological niche modeling for reed canarygrass (Phalaris arundinacea) in floodplain forests of the Upper Mississippi River, USA. We used presence and absence of reed canarygrass from US Army Corps of Engineers forest inventory plots sampled between 2008-2018 as our response variable along with several predictor variables derived from...
Nocardia cyriacigeorgica in a Mallard Duck
Nocardia spp. are opportunistic pathogens of humans, domestic animals, and wildlife that can cause high levels of morbidity and mortality. Reported cases of nocardiosis in Aves are rare. We diagnosed nocardial airsacculitis in a free-ranging mallard duck (Anas platyrhynchos) from Arizona, USA. Histopathology showed multiple granulomas expanding the air sac with intralesional filamentous...
