Remote sensing and in-situ data to support chlorophyll-a mapping in Blue Mesa Reservoir from Sentinel-2 imagery Remote sensing and in-situ data to support chlorophyll-a mapping in Blue Mesa Reservoir from Sentinel-2 imagery
This data set includes estimates of aquatic chlorophyll a concentration and reservoir temperature for Blue Mesa Reservoir, CO. A Random Forest modeling approach was trained to model near-surface aquatic chlorophyll a using near-coincident Sentinel-2 satellite imagery and water samples analyzed for chlorophyll a concentration. The trained chlorophyll a model was applied to Sentinel-2...
Lengths, hatch dates, and piscivory for age-0 largemouth bass in Wisconsin lakes Lengths, hatch dates, and piscivory for age-0 largemouth bass in Wisconsin lakes
Data include lengths, observations on piscivory, and hatch dates for age-0 largemouth bass in Wisconsin lakes with predicted total length (TL) if the fish would have hatched 7 days earlier or 7 days later.
Experimental testing for radon in laboratory and field using a coupled diffusive membrane and alpha track detector, 2024 Experimental testing for radon in laboratory and field using a coupled diffusive membrane and alpha track detector, 2024
Information on radon occurrence in groundwater systems is important to assess risks from radon exposure. For this study we developed a novel passive method to measure for dissolved radon in groundwater using a coupled diffusive membrane encasing an alpha track (AT) detector. The membrane is gas permeable but water impermeable, which allows for the deployment of AT detectors in aqueous...
Unoccupied Aerial System-mounted image velocimetry and Doppler velocity radar data for computation of river velocity and discharge collected at seven locations in Colorado in 2023 (ver. 2.0, February 2026) Unoccupied Aerial System-mounted image velocimetry and Doppler velocity radar data for computation of river velocity and discharge collected at seven locations in Colorado in 2023 (ver. 2.0, February 2026)
A series of field measurements of surface water velocity derived from video and Doppler velocity radar collected by small unoccupied aircraft systems (sUAS) and portable sensors were collected at seven locations in Colorado, USA, during the summer of 2023. The measurements were utilized to compute surface velocity and discharge using the Probability Concept, Large-Scale Particle Image...
Data in support of groundwater- and surface-water-interactions report—Groundwater and Surface-Water Interactions in the Lower Duwamish Waterway, Seattle, Washington Data in support of groundwater- and surface-water-interactions report—Groundwater and Surface-Water Interactions in the Lower Duwamish Waterway, Seattle, Washington
The U.S. Geological Survey (USGS), in cooperation with the Washington State Department of Ecology (Ecology), conducted a study to describe the current understanding of the regional groundwater system of the lower Duwamish River valley and groundwater and surface-water interactions in the lower Duwamish Waterway. A nearshore site along the western shoreline of the Duwamish River, about 1...
Data Files for the Development of Regional Regression Equations for Flow-Duration Statistics and N-day Low-Flow Frequencies for Ungaged Stream Locations in Puerto Rico Using Data Through Water Year 2018 Data Files for the Development of Regional Regression Equations for Flow-Duration Statistics and N-day Low-Flow Frequencies for Ungaged Stream Locations in Puerto Rico Using Data Through Water Year 2018
Flow-duration statistics at the 99th, 98th, 95th, 90th, 80th, 70th, 60th, and 50th percent exceedance probabilities and annual n-day low-flow statistics for the 1-, 7-, 14-, and 30-day mean low flows with 2-year (0.5 nonexceedance probability), 5-year (0.2 nonexceedance probability), and 10-year (0.1 nonexceedance probability) recurrence intervals were computed for 28 selected streamflow...
