Data Releases

Over the summer of 2022 the USGS deployed temporary seismometers, infrasound arrays, and cameras along several drainages at Mount Shasta, California. Twenty-one debris flows were confirmed by the cameras or other observations. This data set consists of images from cameras placed near three drainages (Bolam Creek, Mud Creek, and Whitney Creek). Images were stored on internal Secure...

This dataset contains dates, geographic locations, and meteorological data associated with non-eruptive debris flows on Mount Shasta. A non-eruptive debris flow an alternate term for volcanic mudflow or lahar. This dataset was derived from existing scientific literature, historical California newspaper records, and open-access weather and climate data.

Broad-area, high-resolution, boat-based water quality mapping surveys of the Sacramento-San Joaquin Delta (Delta) and Suisun Bay were conducted in May, July, and October of 2024. Each survey was comprised of four successive days of high-resolution mapping. The regions covered included the north-south axis of the Delta from the Sacramento River north of Freeport to the Harvey Banks export...

In-situ hyperspectral radiometer deployments offer valuable ground truth data for atmospheric corrections of satellite remote sensing over inland and coastal water bodies. These measurements can also be used to model water-quality parameters directly from hyperspectral observations, making such instruments valuable additions to the U.S. Geological Survey (USGS) water-quality monitoring...

This data release package contains water-use estimates from 1985 to 2015 aggregated to 8-digit Hydrologic Unit (HUC8), county, and aquifer level for the United States. The U.S. Geological Survey (USGS) is responsible for estimating water-use in the United States. In cooperation with local, State, and Federal agencies, the USGS has published estimates of water use in the United States...

Between May 2022 and April 2023, 57 passive seismic measurements were collected in select subwatersheds and arroyos near Los Planes, Mexico. The horizontal‑to‑vertical spectral ratio (HVSR) method is a passive seismic technique that uses a three‑component seismometer to measure the vertical and horizontal components of seismic noise in the range of ~0.3 to 40 Hertz (Hz). Common sources...

News articles which described issues of water availability in the Upper Colorado River Basin were retrieved from the Lexis Nexis database. Articles covered the period January 1, 2000 to March 2, 2024. Thematic coding was used to assess how media described risks associated with water availability, the consequences of and responses to those risks. These data support a multidisciplinary...

Expanded excavations at White Sands National Park have unearthed 20 stratigraphic horizons containing in situ human footprints, megafaunal trackways, and linear features created by travois. Novel radiocarbon dating of conifer pollen, combined with ages of aquatic seeds, refines the chronology of the footprint-bearing sequence to between 23.5 and 21.7 ka. Biomarker, pollen, and...

40Ar/39Ar geochronologic data presented in this data release are from the Yellowstone Plateau volcanic field, which spans an area that covers parts of Wyoming, Idaho, and Montana. These data were collected to determine the age and distribution of caldera-forming ignimbrite deposits associated with the Yellowstone Plateau volcanic field. These data also include the eruptions ages of lava...

The introduction of clade 2.3.4.4b highly pathogenic avian influenza (HPAI) H5N1 into North America in 2021 marked a significant shift in disease dynamics for wild waterfowl populations. To assess infection and seroprevalence trends following this incursion, we leveraged ongoing capture efforts at the Sacramento National Wildlife Refuge Complex between October 2022 and July 2025 to...

A collection of time-series oceanographic data was obtained from locations on Georges Bank and adjacent continental shelf between 1975 and 1984. Measurements available include current, temperature, pressure, light transmission (beam attenuation). The time series is not continuous at any specific location. The originally processed, authoritative netCDF data files are provided in...

The Mineral Hill alkaline complex (MHAC), located on the northwest side of the Black Hills uplift near the Wyoming–South Dakota border, is composed of several alkaline igneous units emplaced into Precambrian metasedimentary rocks and Paleozoic strata. The purpose of this study was to determine whether MHAC garnets are a major host of rare earth elements (REEs) and whether REE patterns...
