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). This data release includes a set of 20 regional...
River Depth, Water Velocity, and Direction at Three Locations Collected in 2021 and 2022 on the Allegheny River Downstream of the Kinzua Dam, Pennsylvania River Depth, Water Velocity, and Direction at Three Locations Collected in 2021 and 2022 on the Allegheny River Downstream of the Kinzua Dam, Pennsylvania
This dataset contains river depth, water velocity, and direction data at three focal areas of research included in the Sustainable Rivers Program (SRP) in the Allegheny River on three dates in 2021 and 2022, at two different river conditions (10,500/10,800 cubic feet per second (cfs) and 6,600 cfs as recorded at USGS gage Allegheny River at West Hickory - 03016000). Data was collected...
Annotated Underwater Images of Round Goby (Neogobius melanostomus) in the Great Lakes from 2020-2023 to Support Deep Learning and Fisheries Assessment Annotated Underwater Images of Round Goby (Neogobius melanostomus) in the Great Lakes from 2020-2023 to Support Deep Learning and Fisheries Assessment
This dataset contains more than 37,000 high-resolution images of natural lake bottom habitats containing round goby (Neogobius melanostomus) captured by autonomous underwater vehicles (AUVs). Round goby are invasive to the Laurentian Great Lakes, but are an important prey item for economically valuable predators, and thus of interest to managers. Individual round goby within each image...
SARS-CoV-2 and Mpox virus spillback component data (North America, 2022) to create risk assessment of spillback at human-wildlife interface SARS-CoV-2 and Mpox virus spillback component data (North America, 2022) to create risk assessment of spillback at human-wildlife interface
We compiled a data set of species by country metrics related to spillback risk for SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) and Mpox viruses. This included aggregating species level estimates of susceptibility to SARS-CoV-2 and Mpox infections, species distribution, and county level infection pressure for both viruses.
Bacteria Enumerations from Surface Water and Bed Sediment Collected from a Mudflat in Palo Alto, California, 2021-2024 Bacteria Enumerations from Surface Water and Bed Sediment Collected from a Mudflat in Palo Alto, California, 2021-2024
USGS scientists enumerated bacteria, including bacterial pathogens, from surface water and sand/sediment collected at an intertidal site (mudflat) near the outfall the Palo Alto Regional Water Quality Control Plant (RWQCP). This site has been monitored for metal concentrations and benthic invertebrate community for the last 30 years. Continued efforts to document changes in pollutant

Shear-wave velocity surface seismic site characterization data at 21 sites in Puerto Rico Shear-wave velocity surface seismic site characterization data at 21 sites in Puerto Rico
In collaboration with researchers at the University of Puerto Rico, Mayaguez, the U.S. Geological Survey acquired multimethod surface seismic imaging data at 21 sites in Puerto Rico for shear-wave velocity site characterization. These data were collected at both permanent and temporary seismograph stations throughout the island, between March 6 and March 18, 2022. Data were acquired...
