Concentrations of per- and polyfluoroalkyl substances (PFAS) and related chemical and physical data at and near surface-water/groundwater boundaries on Cape Cod, Massachusetts, 2016-19 Concentrations of per- and polyfluoroalkyl substances (PFAS) and related chemical and physical data at and near surface-water/groundwater boundaries on Cape Cod, Massachusetts, 2016-19
Groundwater, surface-water, sediment, and associated quality-control samples were collected downgradient from a former fire training area and wastewater infiltration beds on Cape Cod, Massachusetts and analyzed for per- and polyfluoroalkyl substances (PFAS). Samples were collected between July 2016 and February 2019 following U.S. Geological Survey protocols. Field parameters reported...
Neosho Madtom (Noturus placidus) short read archive and whole genome sequence data Neosho Madtom (Noturus placidus) short read archive and whole genome sequence data
Whole genome sequence data from ten Neosho madtom originating from three geographically separated populations. A Neosho madtom genome was de novo assembled and genome size and content were assessed. Genomic DNA was used to construct one small insert paired-end library per fish with an approximate insert size of 300 bp. The library was constructed following the manufacturer's protocol...
Data for volatile organic compounds in groundwater used for public supply across the United States, 2013-19, and data for associated quality-control samples Data for volatile organic compounds in groundwater used for public supply across the United States, 2013-19, and data for associated quality-control samples
This data release includes tables and time-series plots of results for volatile organic compounds (VOCs) analyzed in samples of groundwater used for public supply that were collected by the USGS National Water-Quality Assessment (NAWQA) Project and the California State Water Resources Control Board’s Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP)...
Spatial and temporal variability of surface and bottom summer water temperature at cool-water areas in the Pend Oreille River, Washington (ver. 4.0, April 2026) Spatial and temporal variability of surface and bottom summer water temperature at cool-water areas in the Pend Oreille River, Washington (ver. 4.0, April 2026)
The water temperature data were collected in summer 2021, 2023, 2024, and 2025. Continuously recording temperature loggers were deployed at the confluences of Indian Creek and Duncan Springs in the Pend Oreille River. Loggers were deployed near the substratum and near the surface of the water column. This data release supersedes Mejia, F.H., Torgersen, C.E., Berntsen, E.K., and Johnsen...
USGS National and Global Oil and Gas Assessment Project-China Assessment Unit Boundaries and Assessment Input Forms USGS National and Global Oil and Gas Assessment Project-China Assessment Unit Boundaries and Assessment Input Forms
This data release contains the boundaries of conventional assessment units for the assessment of undiscovered oil and gas resources in China. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The...
Data supporting: Draft Genome Sequence of a Novel Calicivirus from a Brown Bullhead (Ameiurus nebulosus) from Lake Memphremagog, VT Data supporting: Draft Genome Sequence of a Novel Calicivirus from a Brown Bullhead (Ameiurus nebulosus) from Lake Memphremagog, VT
We report a draft genome of a previously undescribed calicivirus from a single brown bullhead inhabiting Lake Memphremagog, Vermont/Quebec. The genome is 7413 nt in length and is most similar to the Atlantic salmon calicivirus (nucleotide identity: 64.7%).
Spatial data associated with tungsten skarn resource assessment of the Northern Rocky Mountains, Montana and Idaho Spatial data associated with tungsten skarn resource assessment of the Northern Rocky Mountains, Montana and Idaho
A mineral resource assessment was performed by the U.S. Geological Survey (USGS) to assess the potential of undiscovered skarn-hosted tungsten resources in the Northern Rocky Mountain region of eastern Idaho and western Montana. This region has seen moderate tungsten trioxide (WO3) production in the past from a variety of mineralization styles including skarn, vein and replacement, and...
Time series of seismic velocity changes during the 2018 collapse of Kīlauea volcano derived from coda wave interferometry of repeating earthquakes Time series of seismic velocity changes during the 2018 collapse of Kīlauea volcano derived from coda wave interferometry of repeating earthquakes
These processed data and provisional codes were created to investigate seismic velocity changes associated with the collapse of Kīlauea caldera during its 2018 eruption. Primary data (i.e., seismic waveforms) are hosted at the Incorporated Research Institutions for Seismology (IRIS; https://www.iris.edu/) and are ingested by the codes included here to reproduce the data analyzed in...
Hatchery-reared Roundtail Chub Data, Arizona USA Hatchery-reared Roundtail Chub Data, Arizona USA
These data were compiled as part of a larger study to evaluate post-stocking survival of hatchery-reared Roundtail Chub. We conducted a two year study (Dec. 2015 – Mar. 2017) in the upper Verde River at the Burnt Ranch stocking location near Paulden, Arizona. Young of year Roundtail Chub were acquired from the Arizona Research and Conservation Center in Cornville, Arizona. Passive...
Channel mapping Glen Canyon Dam to Lees Ferry in Glen Canyon National Recreation Area, Arizona - Data Channel mapping Glen Canyon Dam to Lees Ferry in Glen Canyon National Recreation Area, Arizona - Data
Bathymetric, topographic, and grain-size data were collected from May 2013 to October 2016 along a 15-mi reach of the Colorado River in Glen Canyon National Recreation Area, Arizona by the U.S. Geological Survey Grand Canyon Monitoring and Research Center. The study reach is located from river miles -15 at the base of Glen Canyon Dam to 0 at Lees Ferry. Channel bathymetry was mapped...
Climate and drought adaptation: historical and projected future exposure metrics for Southeastern Utah Group National Parks Climate and drought adaptation: historical and projected future exposure metrics for Southeastern Utah Group National Parks
These data were compiled to evaluate the magnitude and direction of change from historical conditions in climate metrics across the Southeastern Utah Group (SEUG) of National Parks. Objective(s) of our study were to quantify the magnitude and direction of change from historical conditions in climate metrics across SEUG parks at a meaningful scale for land managers and practitioners...
Suspended-sediment, bedload, bed-sediment, and multibeam sonar data in the Chippewa River, WI Suspended-sediment, bedload, bed-sediment, and multibeam sonar data in the Chippewa River, WI
