Data

This data release documents dibromochloropropane (DBCP) data and environmental tracer data used to evaluate long-term trends and the history of DBCP in recharge in California groundwater. DBCP data from the California State Water Resources Control Board’s Division of Drinking Water (SWRCB-DDW), the USGS Groundwater Ambient Monitoring and Assessment Priority Basin Project (USGS GAMA-PBP)...

Pesticide exposure is posited as one of the drivers of arthropod declines, which can in turn affect food availability and safety for vertebrates that consume insects including state and federally endangered species, such as the blunt nosed-leopard lizard (BNLL) (Gambelia sila). State wildlife areas and national wildlife refuges are designed to support species and their habitats; however...

Mineral assemblages, frictional properties, and deformation mechanisms were investigated in samples collected from an outcrop exposure of the Pütürge segment of the East Anatolian Fault Zone, Turkey (Türkiye). X-ray diffraction (XRD) analysis was performed on five samples to determine the minerals present. Triaxial shearing experiments were conducted at the USGS Rock Physics Laboratory...

This dataset provides wave, water level and non-tidal residual (NTR) timeseries for a reanalysis period and future projections for the mid-century. Data are available at nearshore stations across the Salish Sea and are packaged by county. Data support coastal Storm Modeling System (CoSMoS) scenarios and available for a multiple sea-level conditions (0 - 3 m).

This dataset contains offshore fault geometries for frontal thrust splay faults in the Cascadia Subduction Zone (CSZ) that were mapped and developed for use in 3D ground motion simulations (Dunham and others, 2025). There are a total of 6 thrust faults (A-F), three of the faults (A-C) were mapped by interpretation of seismic reflection data (Ledeczi and others, 2024; Lucas and others...

Water was sampled in streams from Butte to near Missoula, Montana, as part of a long-term monitoring program in the upper Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the upper Clark Fork Basin and monitor trace elements associated with...

The dataset is a 3 m spatial resolution Digital Elevation Model (DEM) representing terrain heights in northern Vicksburg, MS and Vicksburg National Military Park in 1938. The DEM was created using structure from motion-aided (SfM-aided) photogrammetry techniques in Agisoft Metashape (v 2.1.1). The aerial images were acquired on June 30, 1938 by Pan American Aerial Surveys for the U.S...

This data release provides a list of published data releases that contain coal exploration drill-hole lithologic, geophysical, and geochemical data from drilling locations in several U.S. States. The text (TXT) file associated with this data release lists the State data releases that are available. The text file will be updated as additional drill-hole data releases are published. The...

Coal exploration drill-hole lithologic, geophysical, and geochemical data from 657 drilling locations in the western Kentucky Mississippi embayment area are provided in this data release. Eighteen drilling locations have multiple sets of data files. The wells are located in eight counties (Ballard, Calloway, Carlisle, Fulton, Graves, Hickman, Marshall, and McCracken) and were drilled...

This data release presents U-Pb LA-ICP-MS ages for eight volcanic and plutonic rocks located in the Wallace and Sandpoint 1° x 2° quadrangle region of in northern Idaho and northwestern Montana. The samples were collected by Jeffery L. Mauk and Micah A. Hernandez in 2021 and were analyzed via LA-ICP-MS in 2023 in the Denver Radioisotope Lab. The weighted mean age from all concordant...

Previous efforts conducted during the breeding season of 2021 affixed two types of light-weight transmitters to adult and pre-fledgling juvenile Common Terns with leg-loop harnesses made of elastic cord. Subsequent observations of marked birds detected minimal differences in the behavior and nesting success of marked adults, nor were any notable impacts on the growth rate or behavior of...

This data release includes six child items with data related to bioenergetics and food web ecology in Shasta Reservoir from 2024 to 2025. Child Item 1: "Zooplankton and Water Temperature Data". This included data on zooplankton density and production (zooplankton_density.csv, zoop_length.csv, and daphnia_egg_ratio.csv) as well as water temperature vertical profiles (temperature_data...
