Data

This data release contains the concentration results of per- and polyfluoroalkyl substances (PFAS) collected in fish tissue and whole blood, bed sediment and biofilm samples from water bodies in and surrounding the Little Bighorn River (LBHR) in Montana in July 2023. A total of 29 filets and whole blood samples were collected from 10 brown trout, 10 catfish, 6 rock bass, and 3 goldeye...

A collaborative effort with US Fish and Wildlife Services is underway with the goal of reducing the spread of flea contracted plague in prairie dog (Cynomys spp.) colonies across the US. One method of flea reduction being studied involves spreading bait pellets containing insecticides commonly used for flea control around prairie dog habitats. To better understand the effectiveness of...

This data release contains nutrient, metal, hormone, pharmaceutical, dioxin, and furan concentration data and field readings associated with surface water samples collected from 35 locations along the New York shoreline of Lake Ontario and surrounding tributaries. Samples were collected from April 2023 through October 2023 at nearshore, embayment, and tributary sites from Niagara River...

This U.S. Geological Survey (USGS) data release contains groundwater quality data for twelve wells in Suffolk County, New York and associated quality assurance results. Samples were collected between 2021 and 2023 and analyzed for per- and polyfluoroalkyl substances (PFAS), pesticides, and pharmaceuticals. Measurements of pH, specific conductance, dissolved oxygen, water temperature and...

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...

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...

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...

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...

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...

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...

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.

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
