Occurrence of Escherichia coli (E coli) and Enterococcus in shallow groundwater adjacent to onsite wastewater treatment systems in Washington, North Carolina
(East Carolina University, 2012)Onsite wastewater treatment systems (OWTS) have been identified as a potential source of microbial contamination of groundwater. Microbial indicators, such as E.coli and Enterococcus, are transported from these systems ... -
Oceanic loading of wildfire-derived organic compounds from a small mountainous river
(2008)Small mountainous rivers (SMRs) export substantial amounts of sediment into the world's oceans. The concomitant yield of organic carbon (OC) associated with this class of rivers has also been shown to be significant and ... -
Origin and geochemical evolution of localized, high-ferrous-iron zones in the Upper Castle Hayne Aquifer, Beaufort County, North Carolina
(East Carolina University, 2017-04-19)The Tertiary Upper Castle Hayne Aquifer (UCHA) is one of the most productive aquifers in North Carolina's Coastal Plain; however, localized zones containing high, dissolved-iron concentrations ([greater than]0.3 mg/L) are ... -

Petroleum Geology of the Utica/Point Pleasant Play in Washington County, Ohio
(East Carolina University, 2016-07-20)The early Late Ordovician interval, known as the Utica-Point Pleasant play, in southeastern Ohio is poorly constrained due to limited data sets. A previous study by the Appalachian Basin Oil and Natural Gas Research ... -
Petrology of the Alderson Formation (Mississippian) in Southeastern West Virginia
(East Carolina University, 1985-12)The purpose of this research is to study in detail the Alderson and Greenville Formations, which have been treated previously only in general studies of the entire Greenbrier Group. The objectives of this thesis are: 1) ... -
QUANTITATIVE COMPARISON OF 2D POROSITY AND PORE GEOMETRY BETWEEN THE UPPER CASTLE HAYNE AQUIFER, NORTH CAROLINA, AND THE BISCAYNE AQUIFER, FLORIDA, USING IMAGE AND GEOSPATIAL ANALYSIS
(East Carolina University, 2012)Karst aquifers are vital sources of groundwater for domestic and industrial use in many parts of the world. To sustain rising population throughout the southeastern United States, karst aquifers are increasingly exploited ... -
Quaternary Evolution of North Core Sound Sound, North Carolina
(East Carolina University, 1/13/16)Northern Core Sound is a shallow lagoonal estuary located behind the Outer Banks barrier islands of eastern North Carolina. Thirty-two vibracores and 155 km of chirp and boomer seismic data have been used to define the ... -
Quaternary Geologic Evolution of the Croatan Beach Ridge Complex, Bogue Sound, and Bogue Banks, Carteret County, NC
(East Carolina University, 2010)Foraminiferal, lithologic, chronostratigraphic, and geophysical data were utilized to describe the Quaternary geologic evolution of the Croatan Beach Ridge Complex, Bogue Sound, and Bogue Banks. The Croatan Beach Ridge ... -
A Record of Holocene Climate Change from the Sunda Shelf, South China Sea
(East Carolina University, 2014)Variations in the East Asian Monsoon (EAM) control weather and regional climate conditions in the heavily populated, agriculturally dependent regions of eastern and southeast Asia. The South China Sea (SCS), especially the ... -
Review and synthesis of the role of structural arches in the Brazilian Amazon lowlands
(East Carolina University, 2017-01-11)In tropical South America, the interplay of tectonics, climate, and base-level influences terrestrial sedimentary processes of modern rivers and their antecedents, leading to transport of large volumes of sediment through ... -
SALINITY DISTRIBUTION IN A CHANNELIZED WETLAND AT EMILY AND RICHARDSON PREYER BUCKRIDGE COASTAL RESERVE, TYRRELL COUNTY, NORTH CAROLINA
(East Carolina University, 2014)The Emily and Richardson Preyer Buckridge Coastal Reserve is a low-lying, peatland-dominated freshwater wetland located in the southern Albemarle Estuarine System. The construction of an extensive canal network that ... -
Sampling in salt marshes for high resolution geological studies
(East Carolina University, 2011-01)Video demonstrating how to take core samples for geological research into sediment formations. -

Source of saltwater intrusion in the Castle Hayne aquifer on the western part of Bogue Banks barrier island, North Carolina
(East Carolina University, 2014)Saltwater intrusion is occurring in the confined Castle Hayne aquifer on the western part of the east-west trending barrier island of Bogue Banks, North Carolina. Of eleven municipal wells that are solely screened in the ... -
Spatial and Temporal Variability in Surficial Seabed Character, Waipaoa River Margin, New Zealand
(East Carolina University, 2012)The Waipaoa River margin, located off the northeast coast of the North Island of New Zealand, provides an opportunity to examine shelf-wide sediment dynamics in a coastal setting. The region is characterized by a narrow ... -
Stratigraphy and petroleum geology of the Alexander silstone in Doddridge and Ritchie Counties, West Virginia
(East Carolina University, 2014)The Upper Devonian Alexander siltstone is an informally named drillers' unit that occurs throughout the eastern half of the gas-producing portion of the Appalachian basin. The Alexander is primarily a gas-producing unit ... -
Stratigraphy and Petroleum Geology of the Blue Monday Sandstone, Central West Virginia
(East Carolina University, 2011)The Upper Mississippian Blue Monday sandstone is a primarily gas producing unit found in several central West Virginia gas fields. The purpose of this study was to characterize the stratigraphy and petroleum geology as ... -
