Stable isotope analyses are reported (the ratios deuterium/protium, carbon-13/carbon-12, oxygen-18/oxygen-16, sulfur-34/sulfur-32, nitrogen-15/nitrogen-14) for ores and related rocks, and mineral occurrences in sedimentary, igneous, and metamorphic rocks from Hicks Dome, Illinois; Clementine copper porphyry prospect, Boulder copper porphyry, and the Elkhorn Mining District, Montana; Pogo...

Dataset contains measured concentrations of PFAS analytes and limits of detection/quantification for 37 total samples. There are 82 total PFAS analytes (7 non-extracted internal standards, 24 extracted internal standards, and 51 target native analytes) and each individual sample has been quantified for all 82 of these compounds. Samples are extracts of plant tissues from three sources...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources of Yemen. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The assessment unit is...

Data include the probability of persistence of 407 Ornate Chorus Frog (Pseudacris ornata) populations across the distribution, as well as the mean habitat suitability, mean winter precipitation, and proportion of the surface that is impervious within each buffered population. Data also include the probability of persistence of Ornate Chorus Frog populations when different buffer sizes...

This data release contains data used to develop and apply a model that estimates the level of direct human-impact on selected groundwater wells in the conterminous United States. An extreme gradient boosting model was developed to estimate the probability of minimal human-impact to water levels in groundwater wells. The model uses human-impact evaluations from regional groundwater...

In the United States, the widespread use of pesticides has led to contamination of groundwater resources. Three decades ago, the U.S. Geological Survey (USGS) established a national water quality monitoring network for groundwater (NWQN-GW). This network provides an overview of groundwater conditions across a wide range of hydrogeologic settings and capture the impacts of pesticide use...

This data release provides data from the 2016 Lesmeister et al. technical report and Mathematica and Python analytical code to model co-occurrence effects between barred (Strix varia) and northern spotted (Strix occidentalis caurina) owls. This data release, containing sample data set and code, is designed to facilitate reproducibility of analyses associated with the manuscript titled...

In 2024 the U.S. Geological Survey (USGS), in cooperation with the Air Force Civil Engineer Center (AFCEC), conducted geophysical surveys at Hanscom Air Force Base, Hanscom Field, and surrounding areas in Massachusetts. Methods used included frequency-domain electromagnetic induction (EMI), ground-penetrating radar (GPR), horizontal-to-vertical spectral ratio (HVSR) passive seismic...

This data release consists of vertical water-quality profile data collected at three locations in West Thompson Lake Connecticut from June to October 2022 and from May to October 2024. The U.S. Geological Survey, in cooperation with the Connecticut Department of Energy and Environmental Protection, collected these data to assess physical property stratification in the West Thompson Lake...

This data publication contains data files collected as part of a field and laboratory effort aimed at estimating the prevalence and altitudinal distribution of avian malaria in forest birds and in the primary vector of malaria in Hawaii, Culex quinquefasciatus in Kīpahulu Valley, Haleakalā National Park, on the island of Maui in 2002 and 2019. To track the spread of mosquitoes and...

This data release contains (1) principal facts of gravity measurements by previous studies and collected by the U.S. Geological Survey in 2006-2024, (2) geophysical grids, and (3) horizontal gradient maxima derived from gravity and magnetic potential fields of the Healdsburg 30 by 60 minute quadrangle, California. Gridded data are provided in geotiff format. These data support modeling...

Projections of vegetated area and vegetated plain elevation for salt marsh units within the Chesapeake Bay (CB) salt marsh complex are calculated using geospatial information for conceptual marsh units defined by Ackerman and others (2022) and Defne and others (2023). The projections are based on the UBMorph model, described in Ganju and others (2025), which estimates changes in areal...
