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.
Stream stage, stream temperature, and climate metrics for 30 streams spanning land use and management gradients in a mixed agricultural region in Pennsylvania and Maryland, 2023 Stream stage, stream temperature, and climate metrics for 30 streams spanning land use and management gradients in a mixed agricultural region in Pennsylvania and Maryland, 2023
This data release contains summary metrics describing stream stage, stream water temperature, and short-term climate conditions (daily precipitation and air temperature) for 30 streams spanning gradients of forest and agricultural land uses and the implementation of agricultural best management practices in a mixed agricultural region in Pennsylvania and Maryland, USA. This setting is...
USGS National and Global Oil and Gas Assessment Project—Santos Basin, Campos Basin, and Espírito Santo Basin provinces of Brazil: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project—Santos Basin, Campos Basin, and Espírito Santo Basin provinces of Brazil: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
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...
Underwater Temperature at Buck Island Reef National Monument Coral Reefs, St. Croix, U.S. Virgin Islands Underwater Temperature at Buck Island Reef National Monument Coral Reefs, St. Croix, U.S. Virgin Islands
The U.S. Geological Survey (USGS) Coral Reef Ecosystems Studies project provides science that helps resource managers tasked with the stewardship of coral reef resources. This data release provides underwater temperature data recorded every fifteen minutes since 2019 at three coral reef locations in St. Croix, U.S. Virgin Islands. The sites are on the fringing reef of the National Park...
