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).

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

This data set includes mortality data from acute toxicity tests with aquatic larvae of the mayfly, Neocloeon triangulifer, exposed to sodium chloride. Two separate tests were conducted and fed diatom diets that were either 7-days-old or 13-days-old.

This data release contains displacement and pore-water pressure data from a field experiment performed November 14, 2003, at Mount Kaba-san, Japan. This experiment generated a shallow landslide, induced by water infiltration from overhead sprinkling, that mobilized into a debris flow. More information about this experiment can be found in Ochiai and others (2004). Extensometer data...
