This data release contains 82.4-kilometer (km) long spatial profiles of geophysical and water-quality properties data acquired along five semi-continuous segments of the Trinity River that were surveyed August 28 – September 1, 2023. The surveyed reaches start at the Elm Fork confluence in the Dallas, Texas metropolitan area and end at a pump station in Scurry, Texas. The geophysical...

Stable isotope analyses are reported (the ratios deuterium/hydrogen, carbon-13/carbon-12, oxygen-18/oxygen-16, and sulfur-34/sulfur-32) for ores and related rocks from the Pea Ridge, Lower Pilot Knob, Bourbon, Iron Mountain, and Kratz Spring iron oxide-apatite deposits in southeast Missouri; the Boss iron oxide-copper-gold deposit in southeast Missouri; the Gagaryah stratiform barite...

The East Pisco Basin is one of several forearc basins situated on the coastal plain of Peru between the Andean Cordillera and Peru-Chile Trench. During the Cenozoic, successive marine transgressions across the East Pisco Basin deposited sequences of Paleogene and Neogene age. Biochronologic studies suggest that a hiatus of approximately 12 million years (~32-20 Ma) separates the youngest...

Data files contain simulated mean, daily, offshore, water temperatures for 20 vertical depths (ranging 4 to 159 m below the surface) for 9 years in the 2040s (2041-2049) and nine years in the 2090s (2091-2099) at two sites in Lake Michigan. One site is located in the northern basin where the National Oceanic Atmospheric Administration (NOAA) has been maintaining a weather buoy since 1979...

The Geospatial Fabric for National Hydrologic Modeling (Viger and Bock, 2014; Bock and others, 2020) is a dataset of hydrographic features and spatial data designed for use within the National Hydrologic Model that covers the conterminous United States (CONUS), Hawaii, and most major river basins that flow in from Canada. This U.S. Geological Survey (USGS) data release consists of the...

This dataset includes processed tree ring data from avalanche paths throughout Colorado, USA. The data were processed in three distinct phases that resulted in this dataset: collection, processing, and avalanche signal analysis. This dataset consists of samples from 1188 cross-sections and increment cores from 1023 individual trees within 24 avalanche paths across the region. From these...

This data release includes SnowModel output for three headwater study areas in Colorado at seven spatial resolutions and from two forcing datasets over a 40-year period from water year 1980 to 2019. The resolutions include 30 m, 50 m, 100 m, 150 m, 250 m, 500 m, and 1,000 m. The model was run with a 3-hour temporal resolution from September 1, 1980 to August 31, 2019. Two meteorology...

We collected fecal scat pellets from 4 black-footed ferrets (Mustela nigripes) in captivity. The ferrets were fed black-tailed prairie dogs (Cynomys ludovicianus) that had previously consumed 0.005% fipronil grain. Fipronil is an insecticide from the phenylpyrazole chemical family. Specifically, ferrets were fed portions of three prairie dogs (60-80 g/day) for one week. We collected scat...

This data release contains foreshore slopes for primarily open-ocean sandy beaches along the United States portion of the Gulf of Mexico (Texas through Florida). The slopes were calculated while extracting shoreline position from lidar point cloud data collected between 2001 and 2018. The shoreline positions have been previously published, but the slopes have not. An alongshore reference...

Surface electrical resistivity tomography (ERT) data were collected in September of 2018 near Ollalie North springs in the upper McKenzie River watershed of west-central Oregon. ERT data were acquired along a single transect on the north bank of Ollalie Creek using a combination of inverse Schlumberger, dipole-dipole, and Wenner arrays. These data were collected to contribute high...

These files consist of scanned field notebooks from long-term research and monitoring conducted in the Loch Vale watershed, Rocky Mountain National Park from June 17, 1981, through September 19, 2023. There are 72 individual PDF files. They are accompanied by a spreadsheet that serves as a pointer to the contents of each notebook, including the range of years in each, start and end dates...

Statistical downscaling methodology was applied to global atmosphere reanalysis, using a 10 year dynamical modeled output as training data, to extend a record of wind and humidity back through the satellite era beginning 1979 or 1980. To extend the record of weather to cover a longer period and thus a greater number of significant fire weather events, statistical downscaling was...
