Concentrations of Per- and Polyfluoroalkyl Substances (PFAS) in Lake Ontario and Surrounding Tributaries, New York, July to September 2023 Concentrations of Per- and Polyfluoroalkyl Substances (PFAS) in Lake Ontario and Surrounding Tributaries, New York, July to September 2023
This data release contains per- and polyfluoroalkyl substances (PFAS) concentration data from surface water samples collected from 35 locations along the New York shoreline of Lake Ontario and surrounding tributaries. Samples were collected monthly from July 2023 through September 2023 at nearshore, embayments, and tributaries from Niagara River to Chaumont Bay. Nearshore and embayment...
Concentrations of polychlorinated biphenyls (PCBs) and associated chemicals in avian tissues collected along the Snow Creek and Choccolocco Creek riparian corridors downstream of the former PCB manufacturing facility, and a reference site, near Anniston, Concentrations of polychlorinated biphenyls (PCBs) and associated chemicals in avian tissues collected along the Snow Creek and Choccolocco Creek riparian corridors downstream of the former PCB manufacturing facility, and a reference site, near Anniston,
These data are comprised of measured concentrations of PCBs, polychlorinate dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), Pb, and Hg, and percent lipid and moisture, in avian tissue samples (egg contents, nestlings, egg shells) collected from the Snow Creek and Choccolocco Creek watersheds downstream of the former PCB facility in Anniston, Alabama, USA. The nearby...
Condition of invasive and native aquatic plants exposed to varied water temperature, chlorine concentration and exposure time Condition of invasive and native aquatic plants exposed to varied water temperature, chlorine concentration and exposure time
Data include treatment water chemistry data (Chlorine concentration, Dissolved oxygen, water conductivity, pH, alkalinity, and hardness) and condition of test plants evaluated 24 hours after testing and then every 4 days for 30 days. Treatment water chemistry data was collected at the beginning and end of the plant treatment period and a subset of times during the treatment period. Plant...
Conditions and Fluorescence Parameters Supporting Method Development and Validation for Microscopic Measurement of the Fluorescence Spectrum of Sedimentary Organic Matter in Geologic Samples Conditions and Fluorescence Parameters Supporting Method Development and Validation for Microscopic Measurement of the Fluorescence Spectrum of Sedimentary Organic Matter in Geologic Samples
Measurement of fluorescence parameters such as λ_max (the wavelength of maximum intensity emission), and red-green (R/G) and blue-green (B/G) quotients allows the use of fluorescence color as a thermal proxy in the exploration for and assessment of hydrocarbon-based energy resource accumulations in petroliferous sedimentary basins. Here, we present data supporting the development of a...
Conodont and petrographic information to support 1:24,000-scale geologic mapping of the Cambrian and Ordovician rocks of the southern Lake Champlain valley Conodont and petrographic information to support 1:24,000-scale geologic mapping of the Cambrian and Ordovician rocks of the southern Lake Champlain valley
Conodonts were collected in the southern Lake Champlain valley to aid in identifying lithostratigraphic units, determining biostratigraphic zonations, and correlating to other regions. The conodonts were identified by experts in Cambrian and Ordovician micropaleontology. Microslides/thin sections were made of different lithostraphigraphic units of the southern Lake Champlain valley to...
Consumer-Grade Side-Scan Sonar Imagery of Invasive Silver Carp in the Lamine River and Blackwater River, Missouri, 2015 Consumer-Grade Side-Scan Sonar Imagery of Invasive Silver Carp in the Lamine River and Blackwater River, Missouri, 2015
In March and September of 2015, the USGS demonstrated the utility of side-scan sonar to image large densities of invasive carp and estimate water volume on the Lamine and Blackwater Rivers, Cooper County, Missouri, USA. A 30-kilometer reach of the Lamine River and 20-kilometer reach of the Blackwater River were surveyed using a Humminbird 1198c sonar system. Fish sampling was conducted...
Continuous and High-Resolution Profiles of the Water Surface and Riverbed Elevation for 282 miles of the Colorado River from Lees Ferry to Pearce Ferry, AZ, 2021 - Data Continuous and High-Resolution Profiles of the Water Surface and Riverbed Elevation for 282 miles of the Colorado River from Lees Ferry to Pearce Ferry, AZ, 2021 - Data
During steady releases from Glen Canyon Dam in 2021, geomorphic data were collected for the Colorado River in Grand Canyon National Park from Lees Ferry to Pearce Ferry. A boat based survey collected position data using Global Navigation Satellite Systems and bathymetry data using a multibeam sonar system. Individual water's edge locations were measured using total stations referenced to...
Continuous dissolved oxygen and temperature data from 2009-2014 at multiple stations along the Portneuf River, Idaho USA Continuous dissolved oxygen and temperature data from 2009-2014 at multiple stations along the Portneuf River, Idaho USA
The Portneuf River sub basin is located in southeast Idaho, USA. The Portneuf River is approximately 100 miles long and drains an area of roughly 1,360 square miles. Five water quality monitoring stations along the Portneuf were measured for dissolved oxygen and water temperature from 2009 to 2014 as part of water quality assessments by the Idaho Department of Environmental Quality...
Continuous Stream Water Quality from Landscapes in the Nellie Juan River Basin, Alaska 2019-2024 Continuous Stream Water Quality from Landscapes in the Nellie Juan River Basin, Alaska 2019-2024
This data release provides continuous water quality measurements from five sites in different landscapes within the Nellie Juan River Basin, Alaska. For each site there are six to seven tables of water quality data: dissolved oxygen (DO), fluorescent dissolved organic matter (fDOM), pH, specific conductance, turbidity, water temperature, and water surface height.
Continuous thermal camera images of summit lava lake activity at Kīlauea volcano, Island of Hawaiʻi, 2010-2018 Continuous thermal camera images of summit lava lake activity at Kīlauea volcano, Island of Hawaiʻi, 2010-2018
The 2008-2018 eruption at the summit of Kīlauea Volcano, Island of Hawaiʻi, provided a unique opportunity to study lava lake behavior due to the accessibility and robust monitoring network (Patrick and others, 2021). During the eruption, the lava lake rose in elevation and enlarged, eventually reaching about 300 m in diameter. The lake exhibited frequent oscillations in elevation due to

This data release includes control point locations, depths, stratigraphic context, and reference information used to constrain the sedimentary and tectonic history of Chehalis Basin
CONUS404 PGW climate forcing variable subset for hydrologic models, 1979-2024: downscaled to 1 km and bias-adjusted for precipitation and temperature CONUS404 PGW climate forcing variable subset for hydrologic models, 1979-2024: downscaled to 1 km and bias-adjusted for precipitation and temperature
Overview This metadata record serves as documentation for the bias adjusted (BA) version of the CONUS404 pseudo-global warming (PGW) atmospheric forcing dataset at 1-kilometer grid spacing (for the original PGW dataset, see Xue and others, 2024).
