Capture-Mark-Recapture and Covariate Data for Demography of Sierra Nevada Yellow-legged Frogs (Rana sierrae) at Summit Meadow, Yosemite National Park, California, 2003-2022 Capture-Mark-Recapture and Covariate Data for Demography of Sierra Nevada Yellow-legged Frogs (Rana sierrae) at Summit Meadow, Yosemite National Park, California, 2003-2022
These data include capture and survey information for a meadow population of endangered Sierra Nevada yellow-legged frogs (Rana sierrae) at Yosemite National Park, California, USA, 2003-2022. The data also include remotely sensed weather covariates related to winter severity (annual April snow water equivalent) and drought severity (Palmer drought severity index) to evaluate their...
Assessing spatial variability of nutrients, phytoplankton, and related water quality constituents in the California Sacramento-San Joaquin Delta at the landscape scale: 2023 High resolution mapping surveys Assessing spatial variability of nutrients, phytoplankton, and related water quality constituents in the California Sacramento-San Joaquin Delta at the landscape scale: 2023 High resolution mapping surveys
Broad-area, high-resolution, boat-based water quality mapping surveys of the Sacramento-San Joaquin Delta and Suisun Bay (Delta) of California, USA were conducted under different environmental/flow conditions in May, July, and October of 2023. The spatial and temporal variability of nutrients, phytoplankton, and related water quality parameters were assessed. This dataset includes...
Supplemental data for Over and Sherwood (2025), Washover and washout locations and landcover classifications after hurricanes Florence, Dorian, Harvey, Ike, and Sandy in North Carolina, Texas, and New York Supplemental data for Over and Sherwood (2025), Washover and washout locations and landcover classifications after hurricanes Florence, Dorian, Harvey, Ike, and Sandy in North Carolina, Texas, and New York
The data in this release support the journal article "Outwash events inhibit vegetation recovery and prolong coastal vulnerability". The research details the vegetation cover in washover and washout locations in North Carolina, Texas, and New York after hurricanes Florence, Dorian, Harvey, Ike, and Sandy. Aerial imagery observations indicate that washout sites create ponds and have a...
USGS National and Global Oil and Gas Assessment Project - Southwestern Wyoming Province, Niobrara Formation Continuous Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project - Southwestern Wyoming Province, Niobrara Formation Continuous Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
This data release contains the boundaries of assessment units and input data for the assessment of undiscovered continuous oil and gas resources in upper Cretaceous Niobrara formation in the Southwestern Wyoming Province, Colorado and Wyoming. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The...
Collection 2 Dynamic Surface Water Extent (DSWE) Proportions: CONUS Annual Proportions 1984-Present Collection 2 Dynamic Surface Water Extent (DSWE) Proportions: CONUS Annual Proportions 1984-Present
Dynamic Surface Water Extent (DSWE) Annual Proportions data summarize occurrence of water on the land surface. DSWE Annual Proportions data are statistical summaries of the USGS Landsat Collection 2 Level-3 DSWE data product (C2-DSWE), a raster dataset of per-pixel surface water inundation status based on the analysis of Landsat 4-9 satellite imagery. DSWE Annual Proportions data average...
Diatom Samples from Ocean Drilling Program Leg 112, Holes 682A and 688E from Offshore Peru Diatom Samples from Ocean Drilling Program Leg 112, Holes 682A and 688E from Offshore Peru
The diatom biochronology of ODP Holes 682A and 688E provides a nearly complete offshore reference section to correspond with onshore studies of the Miocene age materials of the East Pisco Basin of Southern Peru, which is known for its excellent preservation of fossil vertebrates. From these holes a nearly complete sequence of low latitude and northeastern Pacific diatoms has been...
Ring widths, scans of samples, and ancillary data from Sequoia sempervirens (coast redwood) trees and stumps at Fort Ross and Gualala, sampled for dendroseismology in 2021–2024 Ring widths, scans of samples, and ancillary data from Sequoia sempervirens (coast redwood) trees and stumps at Fort Ross and Gualala, sampled for dendroseismology in 2021–2024
Sequoia sempervirens (coast redwood) trees were sampled for a dendroseismological investigation along the North Coast Section of the San Andreas Fault, and the data were fully analyzed, interpreted, and discussed in a journal article and supplemental material (Carroll et al., 2025). Here, were provide data associated with this work: 1200 dpi resolution images of tree cores and stumps...
Point cloud and digital elevation data from terrestrial laser scanning of the San Andreas Fault and coast redwood trees near Fort Ross, California Point cloud and digital elevation data from terrestrial laser scanning of the San Andreas Fault and coast redwood trees near Fort Ross, California
These data are derived from laser scanning surveys of the San Andreas Fault and surrounding groves of trees in Fort Ross State Historic Park, California. Surveys were performed on May 13, 2013 and June 19–20, 2024. The second survey was performed specifically to document the morphology of trees that show signs of past earthquake damage, four of which were sampled for dendroseismology...
Trout mark-recapture and stream temperature and streamflow data from Duck Creek, Montana Trout mark-recapture and stream temperature and streamflow data from Duck Creek, Montana
The data release includes a fish sampling dataset and a dataset of estimates of stream temperature and discharge. These datasets were created to assess how Yellowstone cutthroat trout (Oncorhynchus virginalis bouvieri; formally Oncorhynchus clarkii bouvieri) responded to interannual changes in stream temperature and discharge and the occurrence of non-native brown trout (Salmo trutta)...
Profiles and properties of Martian gully flows from HiRISE DTMs and orthoimages, 2006-2020 Profiles and properties of Martian gully flows from HiRISE DTMs and orthoimages, 2006-2020
This dataset contains shapefiles that describe topographic long profiles of recent Martian gully flows recording various information about the flow and host gully. Each profile has some or all of the following: a profile of the active flow, a profile of the full gully, the location of the channel mouth, a profile recording different types of activity, a shapefile with locations of...
Temperature Data From Wells in Long Valley Caldera, California, 2018-present Temperature Data From Wells in Long Valley Caldera, California, 2018-present
This data release consists of well temperature logs from Long Valley Caldera, California, which have been measured to characterize the spatial and temporal variations of the subsurface heat flow. Two methods were used to measure temperatures. The first method, a portable hand cranked reel with a platinum resistance thermometer (PRT), with an accuracy and precision of 0.1 degrees Celsius...
Spatial data layers for a site prioritization tool for invasive species Spatial data layers for a site prioritization tool for invasive species
These spatial layers were created to provide estimates of non-native species invasion risk across the contiguous United States based on proximity to human population centers and transportation corridors, and proximity to known locations of non-native species. To calculate the human transport risk layer we estimated the proximity to human population centers, transportation corridors, and...
