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.

SHRIMP U-Pb geochronologic data for Elkhorn Mountains Volcanics and Boulder batholith satellite plutons, western Montana, U.S.A. SHRIMP U-Pb geochronologic data for Elkhorn Mountains Volcanics and Boulder batholith satellite plutons, western Montana, U.S.A.
These data are for a geochronologic study of Cretaceous Elkhorn Mountains Volcanics and several discrete satellite plutons adjacent to the Cretaceous Boulder batholith of western Montana. Zircon from the two volcanic units of the Elkhorn Mountains Volcanics and four samples of satellite plutons of the Boulder batholith were dated by sensitive high resolution ion microprobe (SHRIMP). When...
Calibration data from Mount Hamilton, California, for USGS Volcano Science Center gravimeters Calibration data from Mount Hamilton, California, for USGS Volcano Science Center gravimeters
Temporal changes in gravity, also called microgravity in volcano geodesy and exploration geophysics applications, provide a means of measuring mass change beneath the surface—for example, due to the accumulation or withdrawal of water, magma, or other fluids. Relative spring-based gravimeters, however, require calibration to establish consistency between instruments, and to assess...
Modeled riparian plant community habitat suitability along the Colorado River in Grand Canyon in support of resource impact analysis for Post-2026 reservoir operational alternatives Modeled riparian plant community habitat suitability along the Colorado River in Grand Canyon in support of resource impact analysis for Post-2026 reservoir operational alternatives
These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post-2026) Environmental Impact Statement (EIS). These data were used to illustrate how six operational strategies (one baseline and 5 alternatives) for Glen Canyon Dam could affect riparian plant communities along the Colorado River between Glen Canyon Dam and Lake...
Modeled sand transport, sandbar volumes, and reservoir operations for the Colorado River in Grand Canyon in support of resource impact analysis for Post-2026 reservoir operational alternatives Modeled sand transport, sandbar volumes, and reservoir operations for the Colorado River in Grand Canyon in support of resource impact analysis for Post-2026 reservoir operational alternatives
These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post-2026) Environmental Impact Statement (EIS). These data were compiled to predict the impact of different proposed alternatives for Glen Canyon Dam operations on sand resources, including sand mass balance, sandbar volume, and frequency/duration of controlled...
Copper concentrations and associated morphometric data from brook trout (Salvelinus fontinalis) and copper results from macroinvertebrates and zooplankton at 6 lakes in Sequoia National Park, CA, 2021-2022 Copper concentrations and associated morphometric data from brook trout (Salvelinus fontinalis) and copper results from macroinvertebrates and zooplankton at 6 lakes in Sequoia National Park, CA, 2021-2022
This dataset encompasses a series of files related to a comprehensive ecotoxicology research project conducted in high elevation lakes of the Tokopah Basin in Sequoia National Park. The dataset includes detailed sampling data that reflects the copper concentrations at multiple levels of the food web. This dataset also includes morphometric data for collected fish, biomarkers of fish...
Passive acoustic telemetry detections of Black Carp Mylopharyngodon piceus in the Mississippi River Basin; 2021-2023 Passive acoustic telemetry detections of Black Carp Mylopharyngodon piceus in the Mississippi River Basin; 2021-2023
This dataset represents passively detected locations of acoustic telemetry tagged Black Carp in the Mississippi and Missouri rivers near their confluence. These river segments consisted of both open river and impounded habitat present during observed hydrologic conditions from 2021-2023. Receiver arrays were set in known use areas (determined by active relocations of tagged fish) and set...
Erodium pollen data from Morro Bay Salt Marsh Erodium pollen data from Morro Bay Salt Marsh
Presence/absence data for Erodium pollen in a sediment core taken from the Morro Bay Salt Marsh.

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources of the Santos Basin, Campos Basin, and Espírito Santo Basin provinces of Brazil. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment NAGA Project for...
Paleomagnetic Directional Data from 194 sites on Hualalai Volcano, Hawaii Paleomagnetic Directional Data from 194 sites on Hualalai Volcano, Hawaii
Paleomagnetic samples were taken at 194 sites on Hualalai Volcano to obtain characteristic mean remanent magnetic directions using a standard protocol (McElhinny, 1973). Eight (8) to twelve (12) cores were taken at each site with a portable, water-cooled, diamond-coring drill, and oriented in the field exclusively with a suncompass. Measurements were conducted on both a spinner...
Data from Measurements of Creep Rates on northern California Faults, California (ver. 3.0, February 2026) Data from Measurements of Creep Rates on northern California Faults, California (ver. 3.0, February 2026)
This Data Release summarizes repeat survey measurements made to monitor surface fault creep (tectonic movement along faults that occurs without strong shaking from earthquakes) in northern California, mostly in the greater San Francisco Bay Area). Additional description of these data and the methods used to collect them is provided in the included references. This Data Release provides...
Metamorphic map of New Hampshire - A digital representation of the metamorphic map from the State bedrock geologic map of Lyons and others, 1997 Metamorphic map of New Hampshire - A digital representation of the metamorphic map from the State bedrock geologic map of Lyons and others, 1997
This data release provides a vector digital dataset developed from the published metamorphic map of New Hampshire. This data release is a digital representation of the metamorphic map shown on sheet 2 of the bedrock geologic map of Lyons and others (1997). The original publication from 1997 was available in paper only. A scanned raster version of the 1997 map was obtained from the...
Avian species detections recorded under the Integrated Monitoring of Bird Conservation Regions (IMBCR) sampling protocol in Utah, USA during the summer of 2021 Avian species detections recorded under the Integrated Monitoring of Bird Conservation Regions (IMBCR) sampling protocol in Utah, USA during the summer of 2021
The provided 2021 Utah Integrated Monitoring of Bird Conservation Regions (IMBCR) dataset contains avian detection data for each of three bird species (downy woodpecker, olive-sided flycatcher, yellow warbler) breeding in Utah, USA considered in the related manuscript. Data were collected by IMBCR partners during the breeding season from stratified survey grid locations. Each survey grid...
