THE MARCELLUS SHALE: EROSIONAL BOUNDARY AND PRODUCTION ANALYSIS, SOUTHERN WEST VIRGINIA, U.S.A.
(East Carolina University, 1/13/16)The Middle Devonian Marcellus Shale is a natural gas producing formation that was deposited in the Appalachian foreland basin in what is now eastern North America. An unconformity truncates the Marcellus in southern West ... -
Geophysical characterization of onsite wastewater treatment system effects on groundwater quality, eastern North Carolina
(East Carolina University, 1/13/16)Onsite wastewater treatment systems (OWS) are a potential non-point source of pollution that can result in water quality degradation in groundwater and surface water. Locating OWS wastewater plumes in the subsurface often ... -
Holocene Evolution of the Ocracoke Inlet Flood-tide Delta Region, Outer Banks, North Carolina
(East Carolina University, 1/13/16)Numerous studies have been conducted along the Outer Banks (OBX) barrier islands of North Carolina to address Holocene climatic change using a combination of lithological, micropaleontological, stratigraphical, and ... -
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 ... -
Cyclic Deposition of Neogene Phosphorites in the Aurora Area, North Carolina, and their Possible Relationship to Global Sea-Level Fluctuations
(1982)The Neogene phosphorites in the Aurora Area occur within the Miocene Pungo River Formation (units A, B, C, and D) and the Pliocene Yorktown Formation (lower and upper units). These units are characterized by the following ... -
Diagnostic Foraminifera and Paleocology of the Pungo River Formation, Central Coastal Plain of North Carolina
(1982-12)Benthic foraminiferal assemblages of the Pungo River Formation (middle Miocene) from the central North Carolina Coastal Plain indicate deposition in continental shelf environments. In Beaufort and Pamlico Counties, part ... -
Miocene Seismic Stratigraphy, Structural Framework, and Sea-Level Cyclicity: North Carolina Continental Shelf
(1982-12)Preliminary interpretations of over 1000 km of high-resolution seismic reflection data, supplemented by over 100 9-m vibracores, have delineated the shallow stratigraphic and structural framework for several Miocene ... -
Stratigraphy and Petrology of the Pungo River Formation, Central Coastal Plain of North Carolina
(1982-12)Up to 30 m of phosphatic sediments of early and middle Miocene Pungo River Formation were deposited in the north-south-trending Aurora Embayment of North Carolina. These sediments thin to approximately 10 to 15 m over the ... -
Synthesis of Phosphatic Sediment-Faunal Relationships Within the Pungo River Formation: Paleoenvironmental Implications
(1982-12)The lower part of the Pungo River Formation in the Aurora Embayment (units A and B) consists of phosphorite sands and interbedded dolomites that grade southward into calcareous quartz sand (unit CC) associated with a ... -
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) ... -
Latitudinal difference in biodiversity caused by higher tropical rate of increase
(East Carolina University, 2002-06-11)Tropical diversity has generally exceeded temperate diversity in the present and at points in the past, but whether measured differences have remained relatively constant through time has been unknown. Here we examine ... -
Comparative impacts of two major hurricane seasons on the Neuse River and western Pamlico Sound ecosystems
(East Carolina University, 2004-06-22)Ecosystem-level impacts of two hurricane seasons were compared several years after the storms in the largest lagoonal estuary in the U.S., the Albemarle-Pamlico Estuarine System. A segmented linear regression flow model ... -
Comparison of quantification methods to measure fire-derived (black/elemental) carbon in soils and sediments using reference materials from soil, water, sediment and the atmosphere
(2007)Black carbon (BC), the product of incomplete combustion of fossil fuels and biomass (called elemental carbon (EC) in atmospheric sciences), was quantified in 12 different materials by 17 laboratories from different ... -
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 ... -
A high marsh transfer function for sea-level reconstructions in the southern Bay of Biscay.

North Carolina’s Coasts in Crisis: A Vision For The Future
(East Carolina University, 2008-10) -
Past, Present and Future Inlets
(East Carolina University, 2008-12) -
Shoreline Change Within the Albemarle-Pamlico Estuarine System, North Carolina
(East Carolina University, 2008-12) -
Controls on Septic System Wastewater Treatment and Shallow Groundwater Quality in Coastal North Carolina
(East Carolina University, 2009)Excess nitrogen and bacteria concentrations in coastal waters of North Carolina have led to eutrophic conditions, fish kills, and the closure of shellfish waters. Regulatory efforts by the state to reduce nitrogen and ... -
The North Carolina Outer Banks Barrier Islands: A Field Trip Guide to the Geology, Geomorphology, and Processes
