In July and August 2023, 11 passive seismic surveys were conducted at or near the U.S. Geological Survey Kankakee River Research Site in Hanna Township, Indiana. 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 ~0.1 to 50 Hertz...

This dataset contains model input and output files for WRF-Hydro simulations over three wildfire-impacted basins in the western United States: Mill Creek Basin in Montana (Chippy Creek Fire, 2007), North Inlet of Grand Lake in Colorado (East Troublesome Fire, 2020), and East Fork of the Jemez River in New Mexico (Las Conchas Fire, 2011). Each domain includes simulations for three...

This data release contains relative timeseries predictions for a single site at which a low-cost trail camera collects images at a fixed frequency. This site and others like it can be viewed at https://www.usgs.gov/apps/ecosheds/fpe/. These images collected at the site are provided, along with data annotations, to a deep learning ranking model which transforms each image into a relative

Molecularly imprinted polymer-electrochemical sensors are a promising approach for detecting non-electrochemically active contaminants such as per- and polyfluoroalkyl substances. However, exposure of poly(ortho-phenylenediamine) based molecularly imprinted polymer films to strongly acidic conditions can alter the polymer environment and complicate interpretation of electron mediator...

This model application data release contains a 3D hydrodynamic model of the San Francisco Bay and Sacramento-San Joaquin Delta constructed using the D-Flow Flexible Mesh hydrodynamic model code (D-Flow FM; Kernkamp and others, 2011). This model simulates water currents, surface elevations, salinity, and water temperatures throughout the San Francisco Bay and Delta (SFBD) in response to...

This dataset contains estimated probabilities of detecting at least of n zero days of streamflow for river locations across the contiguous United States as a function of drainage area. Also included are the 95-percent confidence intervals around the probability estimates. Probabilities are estimated by survival regression models, which are simple, non-parametric, empirically-based models...

Wetlands play an important role in carbon retention, which is greatly dependent on hydrological conditions. Therefore, the interest in wetland hydrology has increased over recent decades. In wetland hydrology, stable water isotopes (δ2H, δ18O) have found increasing use, as laser-based instruments have become readily available and allow for faster analysis and lower costs. However, the...

The National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota is the site of a 1979 high-pressure crude oil pipeline rupture. Approximately 1.7 million liters of crude oil spilled onto the glacial outwash aquifer. After remediation and natural attenuation, an estimated 25% of the oil remains in the subsurface today. Groundwater monitoring at the site...

The upper portion of the Troublesome Aquifer is the sole source of water for domestic use in the Greater Pole Creek Basin, situated in the western portion of the upper Fraser River Valley in Grand County, Colorado. Data from drilling records for wells installed near and within recent home developments, municipal water-suppliers, water-quality records, and published reports are summarized...

This data release makes available the data used to test and refine a remote sensing approach for estimating river discharge via critical flow theory. In rivers where flow conditions are near critical and well-defined standing waves are present, discharge can be inferred from measurements of wavelength and channel width made on an image. The goals of the study were to: 1) evaluate the

To understand water scarcity issues in the Upper Colorado River Basin (UCRB), our research team collaborated with librarians at the Department of Interior with access to Lexis Nexis to query its newspaper and congressional research databases for topics of interest between 2000 and 2024 in our area of interest in the UCRB. The data were pre-processed into a tabular format and loaded into...

During December 2023, the U.S. Geological Survey collected ground-penetrating radar (GPR) data in select small peat bogs near the Quashnet River to map the depth to bedrock for use as inputs to a groundwater flow model. This data release contains the raw GPR data from 22 GPR profiles covering more than 1.8 kilometers.
