Geometry and Construction History of the Copper Ridge Laccolith, Mount Ellen, Henry Mountains, Utah
(East Carolina University, 2015)The Copper Ridge laccolith is an asymmetric tongue-shaped intrusion located on the southeastern margin of Mount Ellen in the Henry Mountains, Utah. The late-Oligocene to early-Miocene igneous rocks have no syn- or ... -
Geometry and Progressive Development of a Shallow Crustal Intrusive Complex, Mount Hillers, Henry Mountains, Utah
(East Carolina University, 2014)The Henry Mountains of southeastern Utah are five topographic domes, each of which is a separate mid-Tertiary shallow crustal intrusive complex comprised of a cluster of component igneous intrusions. The intrusions were ... -
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 ... -
Geophysical Detection of On-site Wastewater Plumes in the North Carolina Coastal Plain, USA
(East Carolina University, 2014)Nonpoint source pollution (NPS) continues to be the leading cause of water quality degradation in the United States. On-site wastewater systems (OWS) contribute to NPS; however, due to the range of system designs and ... -
The historical foundations of modern earth science education : using the power of history in earth science education
(East Carolina University, 2010)This project is part of a larger collaborative effort between science, math, and education departments at East Carolina University. The project aims to address the common science and mathematics deficiencies of many high ... -
Holocene Climate and Carbon Sequestration via Black Carbon Burial in Sediments
(East Carolina University, 2011)Fire, a global process that depends on climate, volcanic activity, vegetation and human practices is not constant through time and varies at decadal, centennial and millennial time-scales. Wildfires that result in burning ... -
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 ... -
Holocene Stratigraphy and Paleoenvironmental Change of Pamlico Sound, North Carolina, USA
(East Carolina University, 2014)Understanding how coastal systems respond to changes in climate is becoming more important due to the current increased rate of sea-level rise and possible increased hurricane intensity in the future. While coastal ecosystems ... -
Improved Tsunami Modeling Via q-Advanced Special Functions
(East Carolina University, 2013)This thesis studies q-advanced functions that are used as forcing terms in the forced wave equation and the Korteweg-de Vries equation in modeling tsunamis. The model improves existing tsunami models and is compared to ... -
THE INFLUENCE OF FRACTURE CHARACTERISTICS ON GROUNDWATER FLOW SYSTEMS IN FRACTURED IGNEOUS AND METAMORPHIC ROCKS OF NORTH CAROLINA (USA)
(East Carolina University, 2013)The yield of water wells drilled in crystalline rock aquifers is determined by the occurrence and interaction of open, saturated fractures which decrease with increased depth, outside of the influence of large-scale features ... -
An Integrated Method for Monitoring Material Transport in a Coupled Land-Estuary System Following a Dynamic Storm Event : The Neuse River and Estuary, NC and Hurricane Irene
(East Carolina University, 2013)Coastal aquatic environments are complex and dynamic systems that are influenced by both marine and terrestrial processes such as waves, tides, winds and freshwater discharge. Rivers are conduits that transport freshwater ... -
Late Holocene evolution of Currituck Sound, North Carolina, USA : environmental change driven by sea-level rise, storms and barrier island morphology
(East Carolina University, 2012)Coastal evolution is an increasingly important area of study, especially with the projected rise in sea level, increase in storm intensity, and population increases along the nation's coasts. In order to predict how the ... -
Lithic Fragments : Sand, Stones, and Spirituality
(East Carolina University, 2011)The work in this thesis exhibition is a reflection of my spiritual journey, a consecration of both the mundane and profound, and my search for transcendence. Repetitive action becomes meditation; each piece becomes a prayer. ... -
MAJOR AND TRACE ELEMENT CHEMICAL COMPOSITION OF GAHNITE FROM GRANITIC PEGMATITES AND A METAMORPHOSED MASSIVE SULFIDE DEPOSIT : SIGNIFICANCE FOR PEGMATITE FRACTIONATION AND DISCRIMINATION BETWEEN Li-RICH AND Li-POOR PEGMATITES
(East Carolina University, 2014)Rare-element granitic pegmatites are common hosts to economic deposits of rare metals, including Li, Ta, and rare-earth elements, which are increasing in economic importance due to advancing technology. Gahnite (ZnAl₂O₄) ... -
Mineralogy, Geochemistry, and Genesis of the Valentines Iron Formation, Nico Pérez Terrane, Eastern Uruguay, and Significance for the Redox Conditions of Early Earth's Oceans
(East Carolina University, 2015)The Valentines Iron Formation of eastern Uruguay is one of three well-defined rock units that comprise the Valentines Formation, and is commonly interlayered with felsic and intermediate granulites. The iron formations ... -
Modern Sedimentation And Estuarine Shoreline Change Around Roanoke Island, North Carolina
(East Carolina University, 2015)Croatan and Roanoke sounds in North Carolina (NC) are regions constantly undergoing geomorphic changes associated with sea-level rise, storm events, and anthropogenic modification. These estuaries are part of the larger ... -
Multifunctional experimental assessment in a newly established Mediterranean restored marsh : marsh elevation, carbon accumulation and pollutant concentration reduction
(East Carolina University, 2014)The Delta of the Ebro River (Catalonia, Spain) is among the most important marsh areas in the Western Mediterranean Sea, highly valuable both economically and ecologically. Fluvial sediment reduction by dams in a relative ... -
Occurrence of Escherichia coli (E coli) and Enterococcus in shallow groundwater adjacent to onsite wastewater treatment systems in Washington, North Carolina
