The California State Water Resources Control Board (State Water Board) initiated the Oil and Gas Regional Monitoring Program (RMP) to assess effects of oil and gas development on groundwater (GW) designated for any beneficial use. The U.S. Geological Survey (USGS) is the technical lead in conducting the RMP through the California Oil, Gas, and Groundwater (COGG) Program, working in...

The U.S. Geological Survey in cooperation with the Upper Arkansas Water Conservancy District, created a numerical groundwater-flow model for the Wet Mountain Valley alluvial aquifer using the finite-difference MODFLOW code with the Newton formulation solver. This numerical groundwater-flow model simulates water-budget components, groundwater and surface-water interactions, and evaluates...

The Landscape Water Requirement Satisfaction Index (L-WRSI) is an extension of the well-established water requirement satisfaction index (WRSI), which is an indicator of crop performance based on the availability of water to the crop during a growing season, by including the entire landscape and not just crop growing regions. L-WRSI is created using components generated by the VegET...

Note: This data release has been preceded by version 1.0, available here: https://doi.org/10.5066/P97KZJGP. The data release presents observations of riparian vegetation, topography, and sediment quality in five river reaches of the Lower Virgin River extending downstream 62 river kilometers (rkm), from near the town of Littlefield (Arizona) to approximately 15 rkm upstream from the...

New geophysical data, including density and magnetic susceptibility measurements, were collected in the Grouse Creek and Utah part of the Jackpot 30' x 60' quadrangles in Box Elder County, Utah and Cassia County, Idaho. The release contains 324 new gravity measurements merged with a 2013 compilation. These data were inverted for basin thickness and basement density variations. The...

Multiple subaerial landslides adjacent to Prince William Sound, Alaska (for example, Dai and others, 2020; Higman and others, 2023; Schaefer and others, 2024) pose a threat to the public because of their potential to generate ocean waves (Barnhart and others, 2021, 2022; Dai and others, 2020) that could affect towns and marine activities. One bedrock landslide on the west side of Barry...

The Edwards and Trinity aquifers are major sources of water for agriculture, industry, and urban and rural communities in south-central Texas. Both the Edwards and Trinity aquifers are classified as major aquifers by the State of Texas. The dissolution of the carbonate rocks composing the Edwards and Trinity aquifers results in distinctive landforms rich in both springs and karst...

This release provides inventories of georeferenced evidence pertaining to extreme waves on Anegada, a low Caribbean island perched south of the Puerto Rico Trench: CORAL BOULDERS AND COBBLES -- Derived offshore, found inland. Boulder star coral Orbicella franksii (37 localities), brain coral Pseudodiploria strigosa (171), elkhorn coral Acropora palmata (36), mustard hill coral Porites...

This data release contains multiple data layers and describes the processing steps associated with the U.S. Geological Survey Professional Paper 1900 "Prospectivity Mapping for Geologic Hydrogen". The data comprise the geologic and geophysical inputs used in support of the U.S. Geological Survey's efforts to create the first map of geologic hydrogen prospectivity within the U.S.

The U.S. Geological Survey, in cooperation with the Federal Highway Administration (FHWA) and the Connecticut, Massachusetts, and Rhode Island Departments of Transportation (DOTs), gathered geospatial data to facilitate the development of a regional Stochastic Empirical Loading and Dilution Model (SELDM) application (Granato and others, 2023). As part of this study, the surficial geology...

In 2022, the U.S. Geological Survey (USGS) New England Water Science Center, in cooperation with the New Hampshire Department of Transportation (NHDOT), surveyed four transportation infrastructure sites with frequency-domain electromagnetic induction (EMI) instruments and one site with ground-penetrating radar (GPR) to aid traditional geotechnical site characterizations performed by...

This data release includes vertical water-quality-profile data from April 2021 to April 2023 at four stations in the Mystic River embayment and three stations in the Norwalk River embayment in Connecticut. These stations are part of a discrete and continuous water-quality monitoring project in embayments on Long Island Sound to support nutrient management activities in Connecticut. The...
