Great Lakes Restoration Initiative: Upper East River in-stream phosphorus dynamics data during runoff events in 2022 and 2023 Great Lakes Restoration Initiative: Upper East River in-stream phosphorus dynamics data during runoff events in 2022 and 2023
Nutrient and soil runoff from agricultural fields in the Upper East River basin contribute to eutrophication in downstream waters like Lake Michigan. Phosphorus is often the limiting nutrient in freshwater ecosystems and the binding of dissolved phosphorus to suspended sediment can reduce its bioavailability. These data provide information about what size particles are binding phosphorus...
Model application data for co-developed surface watershed and groundwater hydrologic models for the Upper Colorado River Basin Model application data for co-developed surface watershed and groundwater hydrologic models for the Upper Colorado River Basin
Co-developed surface and subsurface hydrologic models for the Upper Colorado River Basin and the Colorado Plateaus principal aquifer system were used to investigate the drivers of change in hydrologic water budget components during contrasting recent wet (1982–1999) and drought (2000–2022) time periods in select headwater subregions of the Upper Colorado River Basin. The hydrologic...
Effects of hypoxic exposure on survival of larval grass carp (Ctenopharyngodon idella) Effects of hypoxic exposure on survival of larval grass carp (Ctenopharyngodon idella)
We determined the effects of hypoxia exposure on grass carp larvae survival within certain developmental periods. Our goal was to establish a baseline lethal DO concentration based on both time of exposure and water temperature. In 2023 we used 6 different low dissolved oxygen concentrations (0.2, 0.4, 0.6, 0.8, 1.0 and 1.2 mg/L plus a control of 7.0 mg/L) to test survival during short...
Digital data for a 3D geologic model of the Michigan Basin region, Illinois, Indiana, Michigan, Ohio, and Wisconsin, USA (ver. 2.0, February 2026) Digital data for a 3D geologic model of the Michigan Basin region, Illinois, Indiana, Michigan, Ohio, and Wisconsin, USA (ver. 2.0, February 2026)
This digital GIS dataset and accompanying nonspatial files synthesize model outputs from a regional-scale volumetric 3D geologic model that portrays the generalized subsurface geology of the Michigan Basin region of Michigan, Wisconsin, Illinois, Indiana, and Ohio. The intent of this product is to rapidly and efficiently synthesize large quantities of geologic data from a wide variety of...
Atmospheric fallout radionuclide data and geochemical data for soil cores from four uranium mine sites, Mohave County, Arizona, April 2022 Atmospheric fallout radionuclide data and geochemical data for soil cores from four uranium mine sites, Mohave County, Arizona, April 2022
The data represent sediment depth profiles of gamma-emitting radionuclides and major, minor, and trace elements in native soil locations around four mineralized sites in Mohave County, Arizona. The four sites represent breccia pipe uranium deposits in the Grand Canyon Region in various lifecycle stages of mining: EZ2 complex (exploration), Arizona 1 mine (standby), Pinenut mine (closed...
Chesapeake Bay Land Use/Land Cover (LULC) Database 2024 Edition Chesapeake Bay Land Use/Land Cover (LULC) Database 2024 Edition
The Chesapeake Bay Land Use/Land Cover (LULC) Database facilitates the characterization of the landscape over time for three discrete time periods at 1-meter spatial resolution. The database was developed by Chesapeake Conservancy (CC) in cooperation with the University of Vermont’s Spatial Analysis Laboratory and U.S. Geological Survey (USGS) as part of a 6-year Cooperative Agreement...
Uncrewed Aircraft System (UAS) imagery and data products from a multiscale remote sensing field campaign at a biocrust monitoring site located near Castle Valley, Utah in February 2022 Uncrewed Aircraft System (UAS) imagery and data products from a multiscale remote sensing field campaign at a biocrust monitoring site located near Castle Valley, Utah in February 2022
In February 2022, the U.S. Geological Survey (USGS) National Uncrewed Systems Office (NUSO) conducted uncrewed aircraft systems (UAS) remote sensing flights to support biological soil crust (biocrust) research at an experiment site located near Castle Valley, Utah. Researchers at the USGS Southwest Biological Science Center have managed this site for over 50 years to study the effects of
Per- and polyfluoroalkyl substances (PFAS) measured in the coastal waters around Oahu, Hawai'i in 2019 and 2020 using passive samplers Per- and polyfluoroalkyl substances (PFAS) measured in the coastal waters around Oahu, Hawai'i in 2019 and 2020 using passive samplers
Concentrations of a group of per- and polyfluoroalkyl substances (PFAS) were measured in coastal waters around the island of Oahu, Hawai'i in 2019 and 2020 to provide a measure of exposure to resident fish species commonly harvested for human consumption. These contaminants were sampled using the polar organic chemical integrative sampler (POCIS) which allows for the determination of the...
Survival of juvenile mussels (Lampsilis siliquoidea) exposed to 6PPD and transformation products Survival of juvenile mussels (Lampsilis siliquoidea) exposed to 6PPD and transformation products
This data set includes mortality data from acute toxicity tests with juveniles of the mussel, Lampsilis siliquoidea exposed to 6PPD and 6PPDQ. Concurrently collected analytical chemistry and general water quality measurements are included.
Detection and quantification of 6PPD-quinone in small mouth bass and whole-body coho salmon fry using two sample preparation methods, accelerated solvent extraction and sonication with centrifugation extraction Detection and quantification of 6PPD-quinone in small mouth bass and whole-body coho salmon fry using two sample preparation methods, accelerated solvent extraction and sonication with centrifugation extraction
Concentrations of 6PPD-quinone, a primary transformation product of the rubber tire additive 6PPD, were measured in small mouth bass that were not exposed to 6PPD-quinone and used as quality control fish matrix for method optimization and in whole-body coho salmon fry that were exposed to known water concentrations of 6PPD-quinone during 96-hour acute toxicity exposures. Two different...
GIS Data for Geologic Map of the Hailey 1 x 2 Degree Quadrangle, Idaho GIS Data for Geologic Map of the Hailey 1 x 2 Degree Quadrangle, Idaho
This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the Hailey 1 x 2 degree quadrangle, Idaho (Worl and others, 1991). Attribute tables and geospatial features (lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in Idaho Geological Survey Geologic Map 10 (Worl and...
RSPARROW versions of previously developed SAS-based models of streamflow, suspended-sediment, total nitrogen, and total phosphorus conditions in the Midwest, Northeast, Pacific, Southeast, and Southwest Regions of the United States for water years 2000 - RSPARROW versions of previously developed SAS-based models of streamflow, suspended-sediment, total nitrogen, and total phosphorus conditions in the Midwest, Northeast, Pacific, Southeast, and Southwest Regions of the United States for water years 2000 -
The USGS Spatially Referenced Regression on Watershed attributes (SPARROW) model is a hybrid empirical/process-based mass balance model that can be used to estimate the major sources and environmental factors that affect the supply, transport, and fate of contaminants in streams and surface-water impoundments (Schwarz and others, 2006).
