Database for the Preliminary Geologic Map of the Cherry Hill Quadrangle, Dinwiddie, Sussex, and Greensville Counties, Virginia Database for the Preliminary Geologic Map of the Cherry Hill Quadrangle, Dinwiddie, Sussex, and Greensville Counties, Virginia
The database for the Preliminary Geologic Map of the Cherry Hill Quadrangle, Dinwiddie, Sussex, and Greensville Counties, Virginia geographically straddles the Coastal Plain and Piedmont Provinces along the Tidewater Fall Line. Rocks of the eastern Piedmont Roanoke Rapids terrane crop out in the western part of the quadrangle and consist of greenschist- to amphibolite-facies...
Database for the Surficial Geologic Map of the Charleston Region, Berkeley, Charleston, Colleton, Dorchester, and Georgetown Counties, South Carolina Database for the Surficial Geologic Map of the Charleston Region, Berkeley, Charleston, Colleton, Dorchester, and Georgetown Counties, South Carolina
This database portrays the surface and shallow subsurface geology of the greater Charleston, S.C. region east of 80 degrees 30' west and south of 33 degrees 15' north. The region covers the entirety of Charleston County and portions of Berkeley, Colleton, Dorchester, and Georgetown Counties. Units locally exposed at the surface range in age from middle Eocene to Holocene, but most of the...
StreamStats Channel Width Weighting Services StreamStats Channel Width Weighting Services
This software release contains Python functions for weighting multiple non-independent estimates of a variable. Weighting is determined by the standard error of prediction of each estimate and the correlation between the estimation methods. The methodology for weighting estimates from either two or three different methods is described in Chase and others (2020). A function is also...
Digital subsurface database of previously published well tops, structural features, and contour maps of the Inyan Kara Group, Minnekahta Formation, Minnelusa Formation, Madison Group, and Deadwood Formation, Black Hills region, South Dakota and Wyoming Digital subsurface database of previously published well tops, structural features, and contour maps of the Inyan Kara Group, Minnekahta Formation, Minnelusa Formation, Madison Group, and Deadwood Formation, Black Hills region, South Dakota and Wyoming
This digital data release presents multiple previously published elements of the structural configuration of the Black Hills regional subsurface. The original data within this geodatabase is sourced from multiple U.S. Geological Survey Open File Reports into the hydrology of the Black Hills, stored on the USGS Water Mission Area NSDI Node (Driscoll, 1992; Strobel et al., 1999; Williamson...
Models, Inputs, and Outputs for Estimating the Uncertainty of Discharge Simulations for the Lake Michigan Diversion Using the Hydrological Simulation Program - FORTRAN Model Models, Inputs, and Outputs for Estimating the Uncertainty of Discharge Simulations for the Lake Michigan Diversion Using the Hydrological Simulation Program - FORTRAN Model
This data release contains the models and their inputs and outputs needed to reproduce the findings for the publication by Soong and Over (2022), "Effect of Uncertainty of Discharge Data on Uncertainty of Discharge Simulation for the Lake Michigan Diversion, Northeastern Illinois and Northwestern Indiana." These data were developed in cooperation with the U.S. Army Corps of Engineers...
Data on flea control using fipronil grain bait with black-tailed prairie dogs at Badlands National Park, South Dakota, 2020-2021 Data on flea control using fipronil grain bait with black-tailed prairie dogs at Badlands National Park, South Dakota, 2020-2021
We collected fleas from colonies of black-tailed prairie dogs in Badlands National Park, South Dakota, 2020-2021. Specifically, we tested fipronil grain for flea control on two colonies: Colony A in 2020 and Colony B in 2021. To assess on-host flea numbers (in 2020 and 2021), we anesthetized trapped prairie dogs (and their fleas) with isoflurane in induction chambers for processing. We...
Simulated impacts of feather oiling on avian energetics and migration: R environment model code and raw output Simulated impacts of feather oiling on avian energetics and migration: R environment model code and raw output
This dataset represents a modeling effort intended to explore the impacts of oiling on migratory birds. The purpose of this model is to provide a first principles approach to predict potential biological impacts of altered energetics dynamics in north American migratory birds due to oiling of feathers. This data includes predicted theoretical impacts on migration timing, wintering...
Dissolved organic carbon, total petroleum hydrocarbons and and toxicity assay results for Bemidji, MN (2018) Dissolved organic carbon, total petroleum hydrocarbons and and toxicity assay results for Bemidji, MN (2018)
In crude-oil-contaminant plumes the dissolved organic carbon (DOC) is mainly hydrocarbon degradation intermediates only partly quantified by the diesel range total petroleum hydrocarbon (TPHd) method. To understand potential biological effects of degradation intermediates we tested three fractions of DOC: (1) solid phase extract (HLB); (2) dichloromethane (DCM-total) extract used in TPHd...
Short vs intermediate-term fate of glucose and oxalic acid in surface and subsurface soils of a coastal grassland near Santa Cruz California Short vs intermediate-term fate of glucose and oxalic acid in surface and subsurface soils of a coastal grassland near Santa Cruz California
Though the primary sources of organic matter to soil are plant inputs, the role of microorganisms as mediators of soil organic carbon preservation is increasingly recognized in the context of biological contributions to long-lived soil organic matter. However, current knowledge of sub-soil processes is insufficient to model microbial-derived carbon flow particularly at depth. Using a...
Toxicity Data for Groundwater Contaminated by Petroleum Hydrocarbons near Bemidji, MN (2016) Toxicity Data for Groundwater Contaminated by Petroleum Hydrocarbons near Bemidji, MN (2016)
Management of petroleum-impacted waters by monitored natural attenuation (MNA) requires an understanding of the toxicology of both the original compounds released as well as the transformation products formed during natural breakdown. Here, we report data from a groundwater plume consisting of a mixture of crude oil compounds and transformation products resulting from a crude-oil release...
Nonvolatile dissolved organic carbon and diesel range organics concentrations measured in 2016 at the Bemidji crude oil study site Nonvolatile dissolved organic carbon and diesel range organics concentrations measured in 2016 at the Bemidji crude oil study site
The Bemidji crude oil spill site is a long-term USGS study site to understand the fate of crude oil in the shallow subsurface. A description of the site can be found at https://mn.water.usgs.gov/projects/bemidji. In 2014 concentrations of non-volatile dissolved organic carbon (NVDOC) were three times higher than diesel range organics (DRO) in the contaminant plume*. This is important...
Groundwater Quality Data from the Upper Hudson and Central New York River Basins, New York, 2017 Groundwater Quality Data from the Upper Hudson and Central New York River Basins, New York, 2017
From May to December 2017, 48 environmental samples and six quality control samples were collected throughout the Upper Hudson and Central New York River Basins. Samples were collected from nine production wells and 11 domestic wells in the Upper Hudson River Basin, and 14 production wells and 14 domestic wells in the Central New York River Basin. Of the total wells sampled, 22 were...
