Electromagnetic Induction and Ground-Penetrating Radar Surveys at Transportation Infrastructure Sites in New Hampshire, 2022 Electromagnetic Induction and Ground-Penetrating Radar Surveys at Transportation Infrastructure Sites in New Hampshire, 2022
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...
Water quality vertical profile data to support embayment monitoring in Long Island Sound, Mystic and Norwalk Embayments, Connecticut, 2021-2023: U.S. Geological Survey data release Water quality vertical profile data to support embayment monitoring in Long Island Sound, Mystic and Norwalk Embayments, Connecticut, 2021-2023: U.S. Geological Survey data release
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...
Daily baseflow discharge and daily stream and baseflow total dissolved solids (TDS) loads for selected locations in the Upper Colorado River Basin for water years 1986 – 2020 Daily baseflow discharge and daily stream and baseflow total dissolved solids (TDS) loads for selected locations in the Upper Colorado River Basin for water years 1986 – 2020
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 Elevation Data from the Siletz River, 2017-18 Water Surface Elevation Data from the Siletz River, 2017-18
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...
