Data Releases

This dataset is composed of 253 Differenced Normalized Burn Ratio (dNBR) images. Each dNBR represents a rough measure of fire-related vegetation change for wildfires (>400 ha) that occurred in the Sky Island Mountains within the Madrean Archipelago Ecoregion of the United States and Northern Mexico. These fires occurred between 1985 and 2011 and were mapped using Landsat 5 and Landsat 7 satellite

This Data Release provides records of fish species abundance collected during summer 2015 using single pass backpack electrofishing within sections of Owens Creek, Big Hunting Creek, and Blue Blazes Creek (a tributary to Big Hunting Creek) in Maryland (USA). We also provide water and air temperature data collected during at 30 minute increments summers of 2015 and 2016. Stream physical habitat dat

This data release includes three types of data used in habitat modeling, and predictions from the habitat models. (1) Predictor rasters for proportion urban development within 1-km radius, proportion exurban within 1-km radius, vector ruggedness measure (VRM) within 500-m radius, topographic position index (TPI) within 500-m radius. (2) Twenty-nine null models for space use for 29 different golden

This dataset contains information on the degree of potential human influence near 2228 groundwater wells in the U.S. glacial aquifer system. Data include well identification, name, latitude, longitude, potential-human-influence category, percent urban and crop land use in a 500 meter radius around each well, and measures of county-based groundwater use and irrigation.

The point and polygon layers within this geodatabase present the global distribution of mineral resource features (deposits, mines, districts, mineral regions) for 22 minerals or mineral commodities considered critical to the economy and security of the United States as of 2017. These data accompany the report by Schulz and others (2017) which provides national and global information on antimony (

Spatially accurate annual crop cover maps are an important component to various planning and research applications; however, the importance of these maps varies significantly with the timing of their availability. Utilizing a previously developed crop classification model (CCM), which was used to generate historical annual crop cover maps (classifying nine major crops: corn, cotton, sorghum, soybe

This dataset accompanies the publication, 'In situ LA-ICPMS U-Pb dating of cassiterite without a known-age matrix-matched reference material: Examples from worldwide tin deposits spanning the Proterozoic to Tertiary', published in Chemical Geology (https://doi.org/10.1016/j.chemgeo.2018.03.008), which reports a LA-ICPMS analytical procedure for dating cassiterite, a main ore mineral in tin deposit

Environmental DNA (eDNA) detection is a rapidly expanding technique used to non-invasively detect cryptic, low density, or logistically difficult-to-study species, such as imperiled manatees. Genetic material shed into the environment through tissue and body fluids is concentrated from water samples and analyzed for the presence of targeted eDNA. To help delineate manatee habitat ranges, high use

The U.S. Geological Survey obtained measurements of channel geometry, flow velocity, and river discharge from five rivers in Alaska September 18-20, 2016, to support research on remote sensing of river discharge. The streamflow data were acquired from the Knik, Matanuska, Chena, and Salcha Rivers and Montana Creek using TeleDyne RD Acoustic Doppler Current Profilers (ADCPs), including the RioPro,

These data are comprised of measurements of metals (cobalt, nickel, copper, zinc, cadmium, and lead), anions (fluoride, chloride, nitrite, bromide, nitrate, sulfate, and phosphate), dissolved organic carbon, and major cations (sodium, magnesium, potassium, calcium, manganese, iron, and strontium) in surface and pore water samples collected during an assessment of the impacts of mining-related meta

hese data sets are is a compilation of bird and environmental samples obtained from 6 sites in Maricopa County, Arizona on the dates shown. Sites were only visited and sampled if they had Rosy-cheeked lovebirds coming to bird feeders at the location and with the permission of the property owner. Two swab samples were obtained from each captured bird and 3 swab samples were collected from the envir

Migratory species provide important benefits to society, but their cross-border conservation poses serious challenges. By quantifying the economic value of ecosystem services (ES) provided across a species range and ecological data on a species habitat dependence, we estimate spatial subsidieshow different regions support ES provided by a species across its range. We illustrate this method for mig
