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...
Watershed Model Input Data for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert Watershed Model Input Data for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert
This U.S. Geological Survey data release presents watershed model input point data aggregated for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert. The original source data was aggregated onto a 200-meter grid, and then converted to a point dataset with each point representing the centroid of a grid cell. The dataset includes information on elevation...
Factors affecting the spatial distribution of Niangua Darters (Etheostoma nianguae) in the Osage River basin, Missouri, USA, 2010-2011 Factors affecting the spatial distribution of Niangua Darters (Etheostoma nianguae) in the Osage River basin, Missouri, USA, 2010-2011
These data include information from 74 sampled stream reaches in the Osage Ecological Drainage Unit (EDU) within the Osage River Basin, Missouri. Streams with a Strahler order from three to six were systematically sampled to assess Niangua darter resource selection across three spatial scales macrohabitat, reach, and watershed scale. Variables used to explain Niangua darter presence at...
The reproductive development of wild-caught Black Carp Mylopharyngodon piceus in North America related to size and age at maturation from 2015 through 2023 The reproductive development of wild-caught Black Carp Mylopharyngodon piceus in North America related to size and age at maturation from 2015 through 2023
This study provides data on the reproductive biology and age of Black Carp (Mylopharyngodon piceus) from various rivers in the Mississippi River Basin. A total of 549 fish samples, collected opportunistically between 2015 and 2023, underwent macroscopic and histological staging to assess reproductive development. Specimens were captured by commercial fishermen and biologists and sent to...
