Data for assessing the susceptibility of groundwater used for domestic-supply, California

This dataset provides groundwater age estimates for 175 wells used as domestic supply in four selected areas of California. Groundwater ages were estimated by calibration of environmental tracers (tritium, tritiogenic helium-3, sulfur hexafluoride, carbon-14 and radiogenic helium-4) to lumped parameter models (LPMs). Calibrated lumped parameter models provide the optimal mean age and...

Datasets Used to Create Generalized Potentiometric Maps of the Fort Union, Hell Creek, and Fox Hills Aquifers within the Standing Rock Reservation

This data release includes text files of well data and shapefiles of potentiometric contours of the Fort Union, Hell Creek, and Fox Hills aquifers within the Standing Rock Reservation. The data accompanies a USGS scientific investigations map from Anderson and Lundgren (2024). The Standing Rock Sioux Tribe (the Tribe) of North and South Dakota and the U.S. Geological Survey (USGS)...

This data release complements the following publication: Solares-Colón, M. M., Goldberg D.E., Melgar, D., Vanacore, E.A., Sahakian, V.J., Yeck, W.L., Hernandez, F., López-Venegas, A.M (2025). Slow rupture, long rise times, and multi-fault geometry: The 2020 M6.4 southwestern Puerto Rico mainshock. Geophysical Research Letters, 52, e2024GL109740. https://doi.org/10.1029/2024GL109740...

Supporting Information for 'Detection of Landslide-Generated Tsunami by Shipborne GNSS Precise Point Positioning'

This data release contains supporting information for the manuscript: Manaster, A.E., Sheehan, A.F., Goldberg, D. E., Barnhart, K. R., & Roth, E. H. (2025). Detection of landslide‐generated tsunami by shipborne GNSS precise point positioning. Geophysical Research Letters, 52, e2024GL112472. https://doi.org/10.1029/2024GL112472 Supporting information falls into two categories: 1. Data is...

Peak-flow frequency analyses for selected streamgages in and near Lincoln County, Montana

This data release contains peak-flow frequency analyses for selected streamgages in Lincoln County, Montana, along with information documenting the input data and specifications for the analyses. The analyses were performed using the methods described by Siefken and others (2025).

Pedestrian evacuation time maps, population estimates, and cruise ship passenger estimates for USVI tsunami-hazard zones

These datasets support the conclusions in the journal article entitled "Population vulnerability of residents, employees, and cruise-ship passengers to tsunami hazards in complex seismic regions: a case study of the U.S. Virgin Islands" as described in the abstract below: Reducing the potential for loss of life from tsunamis is challenging on islands located in complex seismic regions...

Data for Investigation of Egg Mortality in a Louisiana Population of Endangered Whooping Cranes

This data set describes the genomic bacterial analysis of swabs and tissues collected from whooping cranes in Louisiana. The data includes targeted analysis from quantitative PCR for bacterial pathogens.

Cosmogenic 26Al/10Be burial ages and 40Ar/39Ar formation ages for cave sediments and manganese oxide ores in Greenbrier and Monroe Counties, West Virginia and Giles County, Virginia

Caves preserve useful archives of fluvial sediments, especially in mountainous landscapes that hinder the preservation of thick, dateable terrace deposits. We used cosmogenic ²⁶Al and ¹⁰Be to date the burial of sediments in four caves along tributaries of the New River: Windy Mouth Cave along the Greenbrier River in West Virginia, Haynes Cave along Second Creek in West Virginia, Bone...

Digital GIS Data for the Bedrock geology of the Evitts Creek and Patterson Creek quadrangles, Maryland, Pennsylvania, and West Virginia from the original map of de Witt and Colton, 1964.

This U.S. Geological Survey (USGS) Data Release provides a digital geospatial database for the Bedrock geology of the Evitts Creek and Patterson Creek quadrangles, Maryland, Pennsylvania, and West Virginia from the original map of de Witt and Colton, 1964. Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent...

Walleye Temperature and Depth Values and Abiotic Conditions of Three Northern Wisconsin Lakes Collected Between June – October 2022

Defining a realized niche using key habitat components like temperature, water clarity, and dissolved oxygen (DO) is important to understanding how distributions and demographics of freshwater fish populations may respond to environmental changes. However, habitat preferences are often defined in a laboratory setting and may not accurately reflect preferred habitat in nature. To define a...

Acoustic Doppler Current Profiler Data for Irondequoit and Sodus Bays in Central New York, 2023

This data release contains acoustic Doppler current profiler (ADCP) data collected in 2023 from two uplooking tripods in bays of Lake Ontario in Central New York. Data were collected at Irondequoit Bay (USGS station number 431314077315901) and at Sodus Bay (USGS station number 431533076582101). Data are organized by bay in child item datasets containing the raw binary data files from the...

Satellite-derived spectral indices to characterize wildfire impacts on forested sites in Glacier National Park, Montana

The dataset contains spectral indices values calculated from Landsat imagery, normalized difference vegetation index (NDVI) and delta normalized burn ratio (NBR, deltaNBR). The spectral indices were computed for 1472 forested sites in the Glacier National Park, Montana, over the 1984-2021 period, in areas that were burned or not burned during the Robert Fire of 2003.
