Data

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered oil and gas resources in upper Paleozoic reservoirs of the Wind River, Big Horn, and Powder River Basin provinces, Montana, Wyoming, South Dakota, and Nebraska. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of...

This dataset consists of estimates of population trends for 236 species and species complexes of North American birds, and bird taxonomic, primary habitat biome, or conservation status group relative abundance trajectories. Both sets of estimates cover the period 1970 - 2022. Sources of data include the North American Breeding Bird Survey (BBS), Christmas Bird Count (CBC), Waterfowl...

Landslides hazards pose a serious threat to people and infrastructure in the Federated States of Micronesia (FSM). To develop a comprehensive understanding of the landslides hazards in FSM, the USGS-USAID Landslide Disaster Assistance Team (LDAT) has put together landslide inventories for each state using satellite imagery. Mapping was done using RGB satellite imagery from Maxar, Planet...

This data release includes Al-26/Be-10 cosmogenic nuclide concentrations and burial isochron ages for three locations in central Colorado, USA, with preferred burial ages ranging from ~2 Ma to 600 ka, that provide constraints on geologic mapping and chronostratigraphic correlations of Pleistocene Colorado Rocky Mountain (CRM)-Great Plains deposits. This new dataset helps to validate...

This dataset contains the data from laboratory and field testing of protocols to measure gas fluxes through mass flow meters attached to rigid chambers sealed to the ground. These tests demonstrate the quality of the ground seal and weather conditions around the chamber are critical for the quality of the data obtained from the technique. This measurement approach is useful for...

This dataset contains methane emissions measurements, gas compositions, and methane carbon isotope geochemistry analysis results from orphan oil and gas wells in the Kevin-Sunburst Dome in Toole County, Montana. Emissions measurements were taken between 2021 and 2023, and gas samples were collected in July, 2023.

The U.S. Geological Survey, Western Ecological Research Center collected sediment and accretion data at two marshes in San Francisco Bay, California over the course of 15 months, capturing a full hydrological year and two spring-summer transitions. Sediment traps were deployed monthly in triplicate along transects of increasing distance from sediment sources (i.e., channels) to capture...

The spatial data are results of USGS surveys for Least Bell's Vireo (Vireo bellii pusillus) (LBVI) along the San Luis Rey River for selected years (1996, 1999-2001, 2003-2004, 2007). Data was used to determine abundance and distribution of vireos as part of long-term demographic studies.

This data release contains water quality data from discrete sonde profiles taken at 10 sites on Lake Koocanusa from 2019 through 2024. The profiles include measurements of water temperature, specific conductance, dissolved oxygen, pH, turbidity, and chlorophyll relative fluorescence as well as the depth of the sonde below the water surface. These data were collected as part of a water...

This data set contains toxicity data from short term 7-day chronic water-only bioassays to assess the effects pH on ammonia toxicity to survival and growth of a juvenile fatmucket mussel (Lampsilis siliquoidea). We conducted 4 concurrent exposures at nominal pHs of 7.0, 7.5, 8.0, and 8.5 with varying ranges of ammonia to capture effect concentrations. This data set has three tables: (1)...

We collected cattle GPS location data within three sites across the Great Basin ecoregion. We then coupled these data with multi-resolution remotely sensed vegetation, hydrology, and topographic data to develop a cattle resource selection surface across Nevada and northeastern California. This layer can support grazing management through targeted or rotational grazing by providing a...

This data release contains photographs and photomicrographs from drill cores and cuttings of pre-Middle Jurassic basement rocks that are buried beneath Coastal Plain sedimentary deposits in Florida. These samples provide rare insights into deeply buried rocks that have no surface exposures and no known exposed correlates. These images were acquired to support the characterization...
