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 maps...

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...

This data release contains measured stream discharge and total dissolved solids (TDS) data and estimated values for daily stream TDS loads, daily baseflow discharge, and daily baseflow TDS loads for 205 locations in the Upper Colorado River Basin. The estimated values, which represent conditions between 10/1/1985 and 9/30/2020, were obtained using the Weighted Regressions on Time...

USGS Geochron is a database of geochronological and thermochronological dates and data. The USGS Geochron: Data Compilation Templates data release hosts Microsoft Excel-based data compilation templates for the USGS Geochron database. Geochronological and thermochronological methods currently archived in the USGS Geochron database include radiocarbon, cosmogenic (10Be, 26Al, 3He), fission...

Water-surface elevations were recorded by 12 submerged pressure transducers deployed from fall 2017 to summer 2018 along an approximately 25-km reach of the Siletz River, Oregon. All pressure transducers were deployed in the main channel of the Siletz River. The water-surface elevations were surveyed by using a real-time kinematic global positioning system (RTK-GPS) at each pressure...

Comma-separated values (.csv) file containing data related to mercury in biota collected from the Hells Canyon Reservoir Complex on the Snake River, Idaho and Oregon.

Carbon (C) and nitrogen (N) extracted from soil with water are associated with available plant nutrients and microbial activity, but information about how C and N have changed over time in the U.S. Great Plains is sparse. Optical measurements of absorbance and fluorescence were used to compare dissolved organic matter (DOM) extracted from historic (1947) and contemporary (2018) soil...

In cooperation with the Georgia Department of Transportation, the U.S. Geological Survey (USGS) has prepared geospatial layers representing the locations of USGS streamgages, other weather monitoring locations, and upstream drainage basins of streamgages in the State of Georgia. These layers also include streamgages in nearby states which directly measure waters within Georgia. The...

With the Surface-Water Index of Permanence (SWIPe) we provide a standardized metric for describing one- to five-year anomalies of the annual minimum surface-water extent of streams and wetlands for multiple spatial scales including basin (4-digit hydrologic unit codes [HUCs]) to subwatersheds (12-digit HUCs). Drier conditions are represented by negative SWIPE values that range from 0 to...
