A multiproxy paleoenvironmental reconstruction of Late Quaternary marine sediments: Sunda Shelf, Southern South China Sea
(East Carolina University, 2017-07-18)Two gravity cores were collected from 43 km and 90 km offshore of Kuala Terengganu (western Sunda Shelf, southern South China Sea) at ~60 m water depth to characterize late Quaternary paleoenvironments by using bulk sediment ... -
A Petrologic and Diagenetic Study of the Onondaga Formation, New Jersey
(East Carolina University, 2017-07-18)A petrologic investigation of the Onondaga Formation in New Jersey has never been conducted, although similar studies have taken place in the surrounding states of New York and Pennsylvania. Thirteen sample sites from the ... -
A re-examination of hydrothermal alteration and Fe-Ti oxide relationships in the Skaergaard Layered Mafic Intrusion, East Greenland
(East Carolina University, 2018-05-01)Fractionation between Fe isotopes in igneous systems and hydrothermally-altered rocks is small but significant, and detailed petrographic understanding of rocks is needed to discern the origin of such fractionations. One ... -
Analyzing Estuarine Shoreline Change in Coastal North Carolina
(East Carolina University, 2009)With continued climate change, sea-level rise, and coastal development, concern about shoreline dynamics has expanded beyond oceanfront areas to encompass more protected coastal water bodies, such as estuaries. Because ... -
Assessing the shallow groundwater system as a potential factor in generating storm-water runoff on a North Carolina barrier island
(East Carolina University, 2013)The town of Emerald Isle, located in North Carolina's Outer Banks, experiences significant storm-water runoff and flooding problems during the fall and winter months. The topography of the island influences drainage patterns ... -
ASSESSMENT OF MODERN SEDIMENT STORAGE IN THE FLOODPLAIN OF THE LOWER TAR RIVER, NORTH CAROLINA
(East Carolina University, 2010)Rivers transport water, sediment, and other constituents from the continent to the sea, but in route material can often become stored temporarily or permanently. Along the Atlantic Coast of the United States, coastal plain ... -
Atmospheric Distributions of Polycyclic Aromatic Hydrocarbons (PAHs) in Coastal Northern Gulf of Mexico, USA, Associated with the Deepwater Horizon Oil Spill
(East Carolina University, 2013)The Deepwater Horizon (DWH) oil spill occurred April 20, 2010 to July 15, 2010, releasing a surface slick of crude oil extending to ~176,000 km² in the Gulf of Mexico (GOM). Crude oil is comprised of thousands of organic ... -
Back-Barrier Sediment and Hydrodynamic Processes: Insights from Rodanthe, NC
(East Carolina University, 2016-07-20)Barrier islands are found around the world, and their geomorphic evolution is related to ocean and estuarine processes. Processes including sediment mobilization and shoreline evolution on both the ocean and estuarine side ... -
CHARACTERIZATION AND DEVELOPMENT OF FRACTURE PATTERNS IN DOMED SEDIMENTARY STRATA, PULPIT ARCH, HENRY MOUNTAINS, UTAH
(East Carolina University, 2020-01-10)Fractures in sedimentary rock can be an important factor in influencing fluid migration in the subsurface. In high-porosity sandstones in the upper crust, deformation such as folding typically results in the production of ... -
Characterizing Coastal Subenvironments with Modern Foraminiferal Assemblages: Bear Island and Bogue Banks, North Carolina
(East Carolina University, 2018-08-30)North Carolina's coastline consists of an extensive barrier island system, with inlets acting as pathways for the exchange of sediment and water from estuarine and open ocean environments. Reconstructing past coastal changes ... -
A comparison of watershed nitrogen loading and watershed nitrogen exports from on-site wastewater treatment systems and centralized sewer systems in the North Carolina Coastal Plain
(East Carolina University, 2013)Elevated nitrogen (N) concentrations in groundwater may cause adverse effects to adjacent surface water bodies. In North Carolina, half of the residences use on-site wastewater treatment systems (OWTS), yet they are typically ... -
Decadal-scale evolution of a barrier island : Insights from storm overwash and shoreline change on Ocracoke Island, NC
(East Carolina University, 2014)Eastern North Carolina has over 300 km of barrier islands that comprise the Outer Banks and act as an important buffer from the Atlantic Ocean and boundary to the Albemarle-Pamlico Estuarine System. These islands also draw ... -
Determining structural and stratigraphic controls on natural gas production of the Upper Devonian Gordon sandstone, Catskill delta complex, southern West Virginia
(East Carolina University, 2017-07-26)Understanding the controls on natural gas production from the Upper Devonian Gordon sandstone may help petroleum geologists and reservoir engineers better develop and implement a plan for reservoir restimulation to recover ... -
The Devonian West Falls Formation, implications of sedimentation controlled by preexisting structures, West Virginia
(East Carolina University, 2012)The Devonian (Frasnian) aged West Falls Formation in West Virginia contains gamma-ray signatures that have been interpreted to indicate sedimentation within a foreland (foredeep) basin. The West Falls Formation includes ... -
DISTRIBUTION AND TAXONOMY OF MODERN BENTHIC FORAMINIFERA OF THE WESTERN SUNDA SHELF (SOUTH CHINA SEA) OFF PENINSULAR MALAYSIA
(East Carolina University, 2016-07-13)This study investigates, for the first time, the distribution and taxonomy of modern benthic foraminifera from the western Sunda Shelf, southern South China Sea. The uppermost centimeter of 54 surface sediment samples ... -
Effects of Urbanization on Stream-Riparian Zone Connection along Low Order Coastal Plain Streams of North Carolina
(East Carolina University, 2017-07-18)Headwater stream reaches, vital areas of exchange between upland and aquatic systems, are commonly affected by stream burial because they constitute a large fraction of total stream length and are more economically feasible ... -
EMPLACEMENT AND GROWTH OF LARGE COMPLEX INTRUSIONS IN THE SHALLOW CRUST, HENRY MOUNTAINS, UTAH
(East Carolina University, 2011)Details of magma migration paths in the shallow crust are poorly understood, in part because there are few locations with well-preserved contacts of igneous intrusions and surrounding host rock. The exposures in the Henry ... -
Examination of the 2011 Mississippi River Flood Deposit on the Louisiana Continental Shelf
(East Carolina University, 2014)Floods can dramatically increase the sediment load supplied to continental margins, leading to greater and potentially geochemically unique deposition. The 2011 flooding of the Mississippi River and its discharge into ... -
Examining Coastal Marsh Sedimentation In Northeastern North Carolina
(East Carolina University, 2015)Coastal marshes are critical environments that are ephemeral on geologic timescales. Understanding the dynamics that naturally maintain these systems is becoming increasingly important in the face of accelerated sea-level ... -
EXAMINING THE IRON ISOTOPE GEOCHEMISTRY OF OLIVINE IN THE SKAERGAARD LAYERED MAFIC INTRUSION, EAST GREENLAND
(East Carolina University, 2018-07-24)Despite reports of significant fractionation of iron isotopes occurring under magmatic and hydrothermal conditions, the mechanisms that cause and control fractionation in magmatic systems remain poorly understood. Previous ...
