Organic geochemistry and petrology of Devonian shale in eastern Ohio: Implications for petroleum systems assessment Organic geochemistry and petrology of Devonian shale in eastern Ohio: Implications for petroleum systems assessment
Recent production of light sweet oil has prompted reevaluation of Devonian petroleum systems in the central Appalachian Basin. Upper Devonian Ohio Shale (lower Huron Member) and Middle Devonian Marcellus Shale organic-rich source rocks from eastern Ohio and nearby areas were examined using organic petrography and geochemical analysis of solvent extracts to test ideas related to organic...

Organic petrology and geochemistry of the Sunbury and Ohio Shales in eastern Kentucky and southeastern Ohio Organic petrology and geochemistry of the Sunbury and Ohio Shales in eastern Kentucky and southeastern Ohio
As part of a study to determine the origin of oil and gas in the Berea Sandstone in northeastern Kentucky and southeastern Ohio, 158 samples of organic-rich shale from the Upper Devonian Olentangy and Ohio Shales and the Lower Mississippian Sunbury Shale, collectively referred to as the “black shale,” were collected and analyzed from 12 cores. The samples were analyzed for total organic...

Oil–source correlation studies in the shallow Berea Sandstone petroleum system, eastern Kentucky Oil–source correlation studies in the shallow Berea Sandstone petroleum system, eastern Kentucky
Shallow production of sweet high-gravity oil from the Upper Devonian Berea Sandstone in northeastern Kentucky has caused the region to become the leading oil producer in the state. Potential nearby source rocks, namely, the overlying Mississippian Sunbury Shale and underlying Ohio Shale, are immature for commercial oil generation according to vitrinite reflectance and programmed...

Public and private tapwater: Comparative analysis of contaminant exposure and potential risk, Cape Cod, Massachusetts, USA Public and private tapwater: Comparative analysis of contaminant exposure and potential risk, Cape Cod, Massachusetts, USA
Background Humans are primary drivers of environmental contamination worldwide, including in drinking-water resources. In the United States (US), federal and state agencies regulate and monitor public-supply drinking water while private-supply monitoring is rare; the current lack of directly comparable information on contaminant-mixture exposures and risks between private- and public...

Per- and polyfluoroalkyl substances (PFAS) in New Hampshire soils and biosolids Per- and polyfluoroalkyl substances (PFAS) in New Hampshire soils and biosolids
The U.S. Geological Survey, in cooperation with the New Hampshire Department of Environmental Services, is undertaking a study on per- and polyfluoroalkyl substances (PFAS) in soils and biosolids. The study will characterize PFAS concentrations in shallow soil and selected biosolids throughout the State of New Hampshire, conduct laboratory experiments to improve understanding of how...

Mixed evidence for biotic homogenization of southern Appalachian fish communities Mixed evidence for biotic homogenization of southern Appalachian fish communities
Anthropogenic impacts on the landscape can drive biotic homogenization, whereby distinct biological communities become more similar to one another over time. Land-use change in the Southern Appalachian region is expected to result in homogenization of the highly diverse freshwater fish communities as in-stream habitat alterations favor widespread cosmopolitan species at the expense of...

Genome sequences of 26 white sucker hepatitis B virus isolates from white sucker, catostomus commersonii, inhabiting transboundary waters from Alberta, Canada, to the Great Lakes, USA Genome sequences of 26 white sucker hepatitis B virus isolates from white sucker, catostomus commersonii, inhabiting transboundary waters from Alberta, Canada, to the Great Lakes, USA
We report 26 genomes of the white sucker hepatitis B virus (WSHBV) from the white sucker, Catostomus commersonii. Genome length ranged from 3541 to 3543 bp and nucleotide identity was 96.7% or greater across genomes. This work suggests a geographical range of this virus that minimally extends from the Athabasca River, Alberta, Canada to the Great Lakes, USA.

Machine learning models of arsenic in private wells throughout the conterminous United States as a tool for exposure assessment in human health studies Machine learning models of arsenic in private wells throughout the conterminous United States as a tool for exposure assessment in human health studies
Arsenic from geologic sources is widespread in groundwater within the United States (U.S.). In several areas, groundwater arsenic concentrations exceed the U.S. Environmental Protection Agency maximum contaminant level of 10 μg per liter (μg/L). However, this standard applies only to public-supply drinking water and not to private-supply, which is not federally regulated and is rarely...

Production and characterization of a mouse monoclonal antibody against smallmouth bass (Micropterus dolomieu) IgM Production and characterization of a mouse monoclonal antibody against smallmouth bass (Micropterus dolomieu) IgM
A murine monoclonal antibody (mAb, IgG2a) was produced for the detection of smallmouth bass (Micropterus dolomieu) immunoglobulin (IgM). The antibody is specific for IgM heavy chain and was shown to also recognize the Ig heavy chain of largemouth bass (Micropterus salmoides) and bluegill (Lepomis macrochirus) using Western Blot analysis of plasma from 9 teleost taxa. When applied to the...

American Woodcock singing-ground survey: Comparison of four models for trend in population size American Woodcock singing-ground survey: Comparison of four models for trend in population size
Wildlife biologists monitor the status and trends of American woodcock Scolopax minor populations in the eastern and central United States and Canada via a singing-ground survey, conducted just after sunset along roadsides in spring. Annual analyses of the survey produce estimates of trend and annual indexes of abundance for 25 states and provinces, management regions, and survey-wide...

Comparative morphology of freshwater sculpin inhabiting different environmental conditions in the Chesapeake Bay headwaters Comparative morphology of freshwater sculpin inhabiting different environmental conditions in the Chesapeake Bay headwaters
We compared body morphology of two freshwater sculpin taxa that inhabit distinct environmental conditions in the Chesapeake Bay watershed of eastern North America: Potomac sculpin (C. girardi, Robins; PS) and checkered sculpin (C. sp. cf. girardi; CS). Both taxa are endemic to the study area, but PS are more broadly distributed than CS which are limited to karst groundwater-dominated...

Pore water exchange-driven inorganic carbon export from intertidal salt marshes Pore water exchange-driven inorganic carbon export from intertidal salt marshes
Respiration in intertidal salt marshes generates dissolved inorganic carbon (DIC) that is exported to the coastal ocean by tidal exchange with the marsh platform. Understanding the link between physical drivers of water exchange and chemical flux is a key to constraining coastal wetland contributions to regional carbon budgets. The spatial and temporal (seasonal, annual) variability of...
