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.

Possible Cattle Access Points on Steams within the USGS Showcase Watersheds Derived from 2018 and 2019 NAIP Imagery Possible Cattle Access Points on Steams within the USGS Showcase Watersheds Derived from 2018 and 2019 NAIP Imagery
This data release contains one point shapefile describing cattle access to streams for three USGS showcase watersheds: Smith Creek, Conewago Creek, and Upper Chester River. This data release identifies areas where cattle were able to access the stream, as well as possible cattle access areas. Streams were defined using a combination of geospatial data and aerial imagery and cattle access...
USGS National and Global Oil and Gas Assessment Project - Williston Basin, Bakken and Three Forks Formations Continuous Assessment Unit Boundaries and Assessment Input Data Forms USGS National and Global Oil and Gas Assessment Project - Williston Basin, Bakken and Three Forks Formations Continuous Assessment Unit Boundaries and Assessment Input Data Forms
This data release contains the boundaries of assessment units and input data for the assessment of undiscovered oil and gas resources in the Bakken and Three Forks formations in the Williston Basin province in Montana, North Dakota and South Dakota. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources...
Selected borehole geophysical logs from three contaminant sites in California, Wisconsin, and New Jersey Selected borehole geophysical logs from three contaminant sites in California, Wisconsin, and New Jersey
Borehole geophysical logs were collected to characterize bedrock aquifers at three contamination sites located in California, Wisconsin, and New Jersey. The data were collected by the U.S. Geological Survey (USGS) and the University of Guelph from 2014 to 2015 as part of the U.S. Department of Defense Strategic Environmental Research and Development Program (SERDP) and Environmental...
Data set for a mesocosm to field assessment of the ecological risks associated with neonicotinoids in US streams Data set for a mesocosm to field assessment of the ecological risks associated with neonicotinoids in US streams
Neonicotinoids, a widely used class of insecticide, have been found in surface waters globally. They pose a risk to non-target species found in aquatic environments such as aquatic macroinvertebrates. To better understand the effects of the neonicotinoids imidacloprid, clothianidin and their mixtures on aquatic communities we ran a 30 day mesocosm test. Rock trays were colonized with...
Fractional Estimates of Multiple Exotic Annual Grass (EAG) Species in the Sagebrush Biome, USA, 2016-2024 (ver. 5.0, July 2025) Fractional Estimates of Multiple Exotic Annual Grass (EAG) Species in the Sagebrush Biome, USA, 2016-2024 (ver. 5.0, July 2025)
This dataset provides annual (2016 - 2024) estimates of fractional cover for Exotic Annual Grass (EAG) species and a native perennial bunch grass for rangelands of the western United States. The dataset includes four (five for 2023 and 2024) fractional cover maps per year, accompanied by corresponding confidence maps, for a group of 15 EAG species. The following 15 species are included...
U-Pb zircon data for: Upper Triassic and Jurassic sedimentary rocks from Sonora, MX U-Pb zircon data for: Upper Triassic and Jurassic sedimentary rocks from Sonora, MX
This laser ablation ICPMS U-Pb zircon data set supports stratigraphic, biostratigraphic and age interpretations of the of the fossil-plant-bearing El Game?o Formation of west-central Sonora, Mexico and the potentially age-correlative fossil-plant-bearing Santa Clara and Coyote formations of southeastern Sonora, Mexico. The zircon data provides minimum age constraints (maximum...
