Data

This data release contains 22 horizontal-to-vertical spectral ratio (HVSR) seismic measurements at 21 sites in Franklin County, New York. The HVSR passive seismic method (Lane and others, 2008; Fairchild and others, 2013) is a non-invasive and cost-effective technique for estimating the thickness of unconsolidated sediments over bedrock. This technique uses a single broadband three...

This data release contains 43 horizontal-to-vertical spectral ratio (HVSR) seismic measurements in Erie, Cattaraugus, and Wyoming Counties, New York collected between 2019 and 2023, in cooperation with the New York State Department of Environmental Conservation. The HVSR passive seismic method (Lane and others, 2008; Fairchild and others, 2013) is a non-invasive and cost-effective...

This dataset contains hourly moisture content, salinity, and temperature measurements for sediment within a dune profile at Madeira Beach, Florida, USA. The data was collected between January 25, 2023, and August 31, 2023, following impacts from Hurricane Idalia. Data were collected using 5 moisture probes that extended 90 centimeters (cm) below the surface, with sensors spaced 10 cm...

The floodplains of the Willamette River and its major tributaries in western Oregon comprise a diverse array of natural and human-modified features that collectively support a wide range of habitats used by native fish and other wildlife. Like other large alluvial rivers, the Willamette River floodplain has many water bodies disconnected from the main river channel throughout most of the...

The U.S. Geological Survey (USGS) collected elevation and location data at 24 selected river reaches along the coast of Massachusetts in 2024. These data were collected in cooperation with the Massachusetts Department of Environmental Protection (MassDEP) and the University of Massachusetts at Amherst (UMass Amherst). The 24 tidal rivers were selected based on the following criteria...

In 2014, the U.S. Army Corps of Engineers collaborated with the U.S. Geological Survey to develop regional hydraulic geometry curves for the Boston Mountains in Arkansas. To accomplish this, fourteen stream reaches associated with stream flow-gaging stations operated by the U.S. Geological Survey were evaluated. These study reaches had contributing drainage basin areas ranging from 0.19...

Beaver dams affect stream hydraulics by temporarily impounding water in stream channels. Beaver dams and their associated impoundments can potentially influence streamflow hydrographs and stream hydraulics in multiple ways including altering the magnitude and duration of high flows, temporary storage of storm water, and the range and spatial distribution of water depths and velocities in...

The USGS collected water level time series data sets using a submersible pressure transducer at FORGE WELL 58B-32 during an aquifer test from February 12 to February 16, 2024. Transmissivity of the pumped aquifer was estimated to be 37,520-55,080 square feet per day using a Theis solution for unconfined aquifers provided by AQTESOLV software. The hydraulic conductivity of the aquifer was...

This data release includes hydroacoustic data for the 2022 to 2024 water years at four stations. These stations are part of a discrete and continuous monitoring project in embayments on Long Island Sound to support nutrient management activities in Connecticut. The data were collected by the U.S Geological Survey (USGS) in cooperation with the Connecticut Departments of Energy and...

This data release includes hydroacoustic transect data collected in 2021, 2022, 2023, and 2024 water years at multiple locations throughout four embayments. These locations are part of a discrete and continuous monitoring project in embayments on Long Island Sound to support nutrient management activities in Connecticut. The transect data were collected by the U.S. Geological Survey...

The U.S. Army Engineer Research and Development Center, in collaboration with the U.S. Geological Survey Wetland and Aquatic Research Center, collected hydrographic data to investigate sediment exchange between a back barrier marsh and open embayment through a tidal creek near Avalon, NJ, between July 2021 and August 2022. Data collected include time-series measurements of current...

This data release contains shapefiles of the hydrogeologic provinces of the conterminous United States. The United States Geological Survey (USGS) is developing a National Extent Hydrogeologic Framework (NEHF). In support of that effort, the conterminous United States was subdivided into eight hydrogeologic provinces that are generally based on geologic provinces and subprovinces...
