Data

The data represent sediment depth profiles of gamma-emitting radionuclides cesium-137 (Cs-137), lead-210 (Pb-210), lead-214 (Pb-214), and bismuth-214 (Bi-214) in native soil locations around four mineralized sites in Mohave County, Arizona. The four sites represent breccia pipe uranium deposits in the Grand Canyon Region in various lifecycle stages of mining: EZ2 complex (exploration)...

This data release contains spatially and temporally summarized simulated variables from the National Hydrologic Model infrastructure with the Precipitation-Runoff Modeling System (NHM-PRMS) modeling application forced with Daymet version 4 for the spatial extent of Alaska (Koczot and others, 2025) from January 1980 through December 2021. Variables are summarized to a monthly time step at...

This dataset represents the date and related identification number for each guano sample collected from the western small-footed bat (Myotis ciliolabrum) captured at Chaco Culture National Historical Park, El Malpais National Monument and El Malpais National Conservation Area, Mesa Verde National Park, Pecos National Historical Park, Guadalupe Mountains National Park, and Capulin Volcano...

This data release contains a crosswalk between subwatersheds (12-digit hydrologic unit codes; hereafter, HUC12s) and hydrologic regions (sometimes called "Van Metre regions"). This crosswalk allows for data at the HUC12 scale to be summarized regionally. Hydrologic regions are boundaries of hydrologically distinct areas modified from hydrologic subregions (4-digit Hydrologic units; HUC4s...

The U.S. Geological Survey (USGS), in cooperation with the Wyoming Water Development Office, developed streamflow statistics for active (through September 30, 2021) and discontinued USGS streamgages in and near Wyoming with 10 or more years of daily mean streamflow record. Streamflow at each streamgage was assessed for degree of human alteration owing to dams and diversions before...

This Scientific Data Release is for a spatial geodatabase containing hydrogeomorphic map units within the Neversink Reservoir Watershed, New York, formatted to Geologic Map Schema (GeMS) standards. Hydrogeomorphic map units within this data release are defined as areas with distinct topographic and hydrologic characteristics, which includes both surficial geologic deposits and regions of...

The FSim wildfire simulation model is widely used to generate estimates of burn probability (BP). However, few studies have compared BP models to subsequent wildfires to assess their suitability for estimating near-future wildfire risk. Here, we compared the U.S.D.A. Forest Service’s publicly available BP map for the conterminous U.S. (Short et al., 2020; Dillon et al., 2023) to observed...

These data have been collected by the United States Geological Survey’s Northeast Amphibian Research and Monitoring Initiative (USGS NEARMI) scientists. We collected these data to examine if Bsal was introduced to a site where there was a known pet release in Western, Massachusetts.

This data release provides a single 8-bit grayscale GeoTIFF orthomosaic of Semisopochnoi Island, in Aleutian Archipelago of Alaska (georeferenced in NAD 1983 UTM Zone 60N; EPSG:3373). The orthomosaic was derived from 31 black and white single frame aerial photographs taken in 1952. Also included are the non-georeferenced scans of the original aerial photographs.

Aeromagnetic and gravity surveys of the Skaergaard intrusion in East Greenland were carried out in July–August 1971 as part of a grant to the University of Oregon Center for Volcanology to further study the intrusion to refine the models of crystallization of the body. The total-intensity aeromagnetic survey was flown in early July 1971 at constant barometric altitude of 1.5 km (5000 ft)...

A combined soil water balance, groundwater flow and stream temperature model was developed to simulate stream temperature under historical and future conditions. Soil-Water-Balance code was used to estimate net infiltration past the root zone and surface runoff, which were applied to a transient, three-dimensional MODFLOW 6 model to simulate the water budget for Beaver Creek and the...

The effects of high- and low-flow conditions on biological communities in Alabama streams were investigated by utilizing data on benthic macroinvertebrates, fish communities, hydrology, land use, and water quality. Biological data from streams and rivers in the Mobile River basin and other Gulf Coast drainages was collected from 278 sites between 1999 and 2014. These sites' upstream...
