Data from laboratory experiments to assess seasonal carbon, nitrogen, and phosphorus processing in water and sediments from the Illinois River near Starved Rock Lock and Dam, 2022. Data from laboratory experiments to assess seasonal carbon, nitrogen, and phosphorus processing in water and sediments from the Illinois River near Starved Rock Lock and Dam, 2022.
Data on carbon and nutrient processing in key locations and over seasonal time scales can provide critical information about the concentrations and potential utilization rates of bioavailable constituents that are known to have a role in cyanobacteria harmful algal blooms (cyanoHABs). Laboratory experiments were performed to measure seasonal nutrient processing rates of carbon, nitrogen...
Data from mesocosm experiments to assess metal and nutrient stimulation of Lake Erie and Lake Michigan phytoplankton communities, August 2017 Data from mesocosm experiments to assess metal and nutrient stimulation of Lake Erie and Lake Michigan phytoplankton communities, August 2017
To address how phytoplankton in the Great Lakes respond to macro- and micronutrients, we conducted a bottle incubation enrichment experiment using water collected from blooming (Maumee Bay and Fox River) and non-blooming sites (Detroit River and Ford River) in Lakes Erie and Michigan, respectively, during late summer. Surface water from these locations was collected and taken to Kent...
Data from Methane Emission Measurements and Isotope Geochemistry Samples from Orphan Oil and Gas Wells on the Kevin-Sunburst Dome in Montana, U.S.A., from April 2021 to October 2023 Data from Methane Emission Measurements and Isotope Geochemistry Samples from Orphan Oil and Gas Wells on the Kevin-Sunburst Dome in Montana, U.S.A., from April 2021 to October 2023
This dataset contains methane emissions measurements, gas compositions, and methane carbon isotope geochemistry analysis results from orphan oil and gas wells in the Kevin-Sunburst Dome in Toole County, Montana. Emissions measurements were taken between 2021 and 2023, and gas samples were collected in July, 2023.
Data from Migratory Bird Aerial Surveys and Habitat, Nest Success, and Genetic Samples from Spectacled Eiders (Somateria fischeri) on the Indigirka River Delta, Russia Data from Migratory Bird Aerial Surveys and Habitat, Nest Success, and Genetic Samples from Spectacled Eiders (Somateria fischeri) on the Indigirka River Delta, Russia
This data release contains five spreadsheets of information from aerial surveys of the Indigirka River Delta, Russia, in June of 1993 and 1994, data on habitats where nests of Spectacled Eiders (Somateria fischeri) and other species of waterfowl were observed from 1993 to 1995, and genotypic data from feathers collected from eider nests to determine inter-annual rates of return by...
Data from Paleocene-Eocene sediments of three cores in the Salisbury Embayment, Maryland and Virginia Data from Paleocene-Eocene sediments of three cores in the Salisbury Embayment, Maryland and Virginia
The Surprise Hill core was drilled on the Northern Neck, Northumberland County, Virginia. The studied section consists of glauconitic quartz sands of the upper Paleocene Aquia Formation and silty clays of the lower Eocene Marlboro Clay. Data from this core were compared to the previously documented South Dover Bridge and Howards Tract cores from Maryland. The purpose of this study was to...
Data from Soil and Storm Water Runoff Samples for the Evaluation of Butyl Acrylate Vinyl Acetate in an Arid Environment, Clark County, Nevada Data from Soil and Storm Water Runoff Samples for the Evaluation of Butyl Acrylate Vinyl Acetate in an Arid Environment, Clark County, Nevada
This U.S. Geological Survey data release contains data from soil and storm water samples collected in and around areas in southern Nevada where a polymer-based dust palliative was applied. The applied palliatives were FSB-1000 (Soil Tech, 2012) or Soil-Sement (Midwest Industrial Supply, Inc., 2001) which contain water and the co-polymer butyl acrylate vinyl acetate (BAVA). Samples were...
Data from surface water and sediment nutrient processing experiments associated with the Maumee River (Toledo, OH) during the 2021 growing season Data from surface water and sediment nutrient processing experiments associated with the Maumee River (Toledo, OH) during the 2021 growing season
River-to-lake transitional zones or rivermouths are biogeochemically active sections of the aquatic continuum that are often understudied compared to their adjoining environments. Internal nutrient loading from these transitional zones may be a considerable source of nutrients to lakes and disconnect upstream management initiatives from in-lake improvements. To contextualize internal...
Data from the Study of Stream Corridor Sources of Suspended Sediment and Phosphorus in Plum Creek, Wisconsin, 2016-2018 Data from the Study of Stream Corridor Sources of Suspended Sediment and Phosphorus in Plum Creek, Wisconsin, 2016-2018
Geomorphic assessment and sediment data were collected in 2017 for an integrated sediment fingerprinting and stream corridor-based sediment budget study of Plum Creek, a tributary to the Lower Fox River and Green Bay, Wisconsin. Data were collected for 30 stream reaches and include quantitative and qualitative measurements of channel geometry, bank and gully erosion, soft bed sediment...
Data from time-constrained visual encounter surveys and acoustic surveys for amphibians and reptiles in the Atchafalaya Basin conducted from 2008 through 2016 Data from time-constrained visual encounter surveys and acoustic surveys for amphibians and reptiles in the Atchafalaya Basin conducted from 2008 through 2016
This dataset contains data from time-constrained visual encounter surveys conducted in the Atchafalaya River Basin in South Central Louisiana from February 2008 through July 2016. In addition, it contains vocalization data collected concurrently with the visual encounter surveys and data on presence of tadpoles and larvae. All participants in surveys are included in the dataset...
Data in support of estimation of magnitude and frequency of floods for rural, unregulated streams in and near Virginia and West Virginia Data in support of estimation of magnitude and frequency of floods for rural, unregulated streams in and near Virginia and West Virginia
This data release contains the supporting datasets, tables, and geospatial information generated and analyzed in the 2025 flood-frequency study for Virginia and West Virginia. In this study, the magnitude and frequency of annual peak streamflows were estimated using the Expected Moments Algorithm for 813 streamgages on rural, unregulated streams in and near Virginia and West Virginia...
Data on behavior of adult horses and burros between 2016 and 2020, in Utah and Arizona, USA Data on behavior of adult horses and burros between 2016 and 2020, in Utah and Arizona, USA
We investigated the behavior of feral horses (Equus caballus) at Conger Herd Management Area (HMA), UT, and of burros (Equus asinus) at Lake Pleasant HMA, AZ, and Sinbad HMA, UT between 2016 and 2020 (Sinbad HMA 2016 to 2019; Conger and Lake Pleasant HMAs 2017 to 2020).
