All Data

This data release contains three comma separated value (.csv) tables describing data from alluvial cobbles collected from a Pleistocene alluvial deposit on the noerth side of Poncha Pass, near Salida, Colorado. Tables "DryUnion_Burial_Isochron_Aluminum26_Cyr.csv" and "DryUnion_Burial_Isochron_Beryllium10_Cyr.csv" contain aluminum-26 and beryllium-10 data, respectively, for samples...

This is a data release of a .csv file that provides measurements of structural features in the Grand Canyon region. These data document structural attitudes, used to describe the orientations of geologic features in three dimensions. Included fields describe the type of geologic feature mentioned, the azimuth and inclination of the measurement (for planar data these correspond to the...

The flood model GeoClaw, a program that simulates shallow surface flows by solving the 2D depth-averaged shallow water equations for flow, was used to assess potential downstream flooding risk post-asteroid-impact. The examined hypothetical impact scenarios were derived from the NASA PAIR 2025 Planetary Defense Conference (PDC) risk corridor during Epoch 1: impact energy averages between...

USGS scientists acquired aerial imagery from unmanned aerial vehicles (UAV) to map sagebrush at 25 sites in the Northern Great Plains during June 2023. Data include imagery with 1.5-centimeter (cm) resolution for each 300x300 meter (m) site and imagery at 0.75 cm for each of 10 to 12, 5x5 m plots within each site, and predicted areas of sagebrush for each site from models that classify...

USGS scientists surveyed for American pikas (Ochotona princeps) at sites of documented occurrence before 1980 to evaluate persistance throughout Montana, Wyoming, Idaho, Oregon, and Washington, USA, 2015-2017. Scientists also surveyed for pikas and characterized talus structure and temperature to map talus and identify micro-refugia associated with temperature within a focal study in...

The data set consists of three files pertaining to invasive Brown Treesnakes (Boiga irregularis) and temporally-associated weather covariates on Guam: 1) snout-vent length (SVL) and sex of brown treesnakes (bts_growth.csv), 2) precipitation (bts_rain.csv), and 3) seasonality (bts_season.csv). Snout-vent lengths in millimeters (mm) and sex of 270 individually marked and recaptured brown...

Morphometric data (mass, length, circumference, age) collected during an observation of a radio-telemetered female Burmese python (Python bivitattus) that ingested an adult female white-tailed deer (Odocoileus virginianus), retained the deer within the digestive tract for 10 days, and then vomited the deer coinciding with a drop in air temperature.

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a Soil-Water-Balance (SWB) model of the Red River alluvial aquifer east of Lake Texoma in southeastern Oklahoma. Although the SWB model active area extends into parts of Texas and Arkansas, the SWB model was used to estimate recharge to the Red River alluvial aquifer between...

The North East 2nd Street Superfund site in Happy, Texas, overlies a groundwater plume of primarily carbon tetrachloride (CT) that is contained within an upper transmissive zone of the High Plains aquifer system (hereinafter referred to as the "Ogallala aquifer"). The Ogallala aquifer is contained in Tertiary-age sediments of the Ogallala Formation in the study area, which are described...

This data release presents an update to the Coastal Response Likelihood (CRL) model (Lentz and others 2015); a spatially explicit, probabilistic model that evaluates coastal response for the Northeastern U.S. under various sea-level scenarios. The model considers the variable nature of the coast and provides outputs at spatial and temporal scales suitable for decision support. Updated...

In 2025, the U.S. Geological Survey (USGS), in collaboration with the Cook County Bureau of Technology (BOT), carried out comprehensive hydrographic and water-quality surveys, and activity and disturbance assessments of 34 total water bodies within Cook County, Illinois. These surveys and assessments describe the bathymetry, water-quality conditions, and on-site field crew observations...

This dataset provides observations of meter-scale bright patches near the north and south poles of Mars in summertime images from the Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment (HiRISE).
