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 ... -
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 ... -
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 ... -
Ecological effects of rising sea level on shorezone
(East Carolina University, 2009)This study examines the ecological effects of sea-level rise on shorezone in the Neuse River estuary and western Pamlico Sound, NC. Shorezone is defined here in an ecohydrological context as the area of wetland that extends ... -
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 Estuarine Sediment Dynamics : Insights from the Large, Shallow, Albemarle-Pamlico Estuarine System, NC, U.S.A.
(East Carolina University, 2014)This dissertation investigated the dynamics of estuarine shorelines in the Albemarle-Pamlico Estuarine System (APES). Shoreline change is influenced by human activities (e.g., shoreline modification), and natural processes ... -
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 ... -
Extension of the Late Holocene Sea-Level Record In North Carolina, USA
(East Carolina University, 2015)Future sea-level rise will dramatically affect coastal landscapes and populations. The coast of North Carolina (USA) is particularly vulnerable to sea-level rise because its low-lying coastal plain is expansive, has a low ... -
FATE AND TRANSPORT OF WASTEWATER PHOSPHORUS IN THE NORTH CAROLINA COASTAL PLAIN : A COMPARISON OF WATERSHEDS SERVED BY MUNICIPAL AND ONSITE WASTEWATER SYSTEMS
(East Carolina University, 2013)This study compares the phosphorus (P) treatment efficiency of on-site wastewater systems (OWS) and municipal wastewater treatment systems (MWS) and quantifies impacts each technology has on ground and surface water. ... -
Foraminifera as indicators of hypoxia off Southwest Pass, Mississippi Delta, Gulf of Mexico?
(East Carolina University, 2013)The continental shelf west of the Mississippi River Delta (the Louisiana Bight) experiences seasonal hypoxia that has been increasing in frequency since the second half of the 20th century due to anthropogenic influence. ... -
Foraminiferal and Geochemical Evidence of Environmental Change in Response to Aquaculture in the Setiu Estuarine-Lagoonal System, Terengganu, Malaysia
(East Carolina University, 2013)In many coastal communities, aquaculture is an important part of the local economy, though fish and shrimp farms may threaten habitats in these coastal systems. Aquaculture was introduced to the Setiu estuarine-lagoonal ... -
Geochemistry and Genesis of Late Paleoproterozoic Banded Iron Formations and Metamorphosed Chemical Precipitates Spatially Associated with Pb-Zn Broken Hill-type Mineralization near the Broken Hill Deposit, Curnamona Province, Australia
(East Carolina University, 2014)Banded and massive iron formations (IFs) and garnet- and gahnite-quartz rocks are spatially associated with the giant, late Paleoproterozoic, Pb-Zn-Ag Broken Hill sulfide deposit and hundreds of minor Broken Hill-type ... -
Geology of the Castle Hayne Limestone in the Onslow Quarry, Richlands, NC
(East Carolina University, 2012)The Eocene age Castle Hayne Limestone Formation on the coastal plain of North Carolina is found throughout Onslow County and is mined at the Onslow quarry south of Richlands. This study characterizes the geology of the ... -
Geometry and construction history of a complex intrusive center in the shallow crust, Mount Pennell, Henry Mountains, Utah
(East Carolina University, 2014)Large igneous intrusions grow from incremental emplacement of relatively small batches of magma. The Henry Mountains have been the subject of investigation because multiple, well-exposed intrusive centers are present on ...
