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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
