Geometry and Construction of Upper Crustal Intrusions; Sawtooth Ridge, Henry Mountains, Southern Utah.
(East Carolina University, 8/5/2020)The plumbing systems of volcanos are commonly constructed by interconnected, upper crustal sheet intrusions (i.e. dikes and sills). Active systems and the processes that contribute to their construction are difficult to ... -
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 ... -
GROUNDWATER FLOW IN THE UPPER CASTLE HAYNE AQUIFER: NUMERICAL SIMULATIONS AND STRONTIUM ISOTOPIC INVESTIGATIONS
(East Carolina University, 2019-10-02)The Castle Hayne Aquifer System (CHAS) is the most extensively used aquifer system in the North Carolina Coastal Plain. Heavy groundwater withdrawals from the Upper Castle Hayne Aquifer (UCH) have occurred since the 1960’s ... -
A high marsh transfer function for sea-level reconstructions in the southern Bay of Biscay.

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 Paleoenvironmental Reconstruction of Depositional Environments on the Sunda Shelf, Southwest South China Sea, using a Multidisciplinary Approach
(East Carolina University, 2018-08-22)The last glacial maximum, ca. 21,000 years ago, caused a fall in eustatic sea level of ca. 120 m below present. The low-gradient, shallow Sunda Shelf, Southeast Asia was subaerially exposed during this sea-level lowstand ... -
HOLOCENE PALEOENVIRONMENTAL RECONSTRUCTION OF THE SUNDA SHELF, OFF NORTHEASTERN PENINSULAR MALAYSIA
(East Carolina University, 2017-05-03)In order to understand Holocene paleoenvironmental evolution of the western Sunda Shelf (southern South China Sea), two gravity cores TER15-GC10A and TER15-GC9A were collected (2015) 33 and 37 km offshore of Kuala Terengganu ... -
A Holocene record of climate-driven shifts in coastal carbon sequestration
(2009)A sediment core collected in the mesohaline portion of Chesapeake Bay was found to contain periods of increased delivery of refractory black carbon (BC) and polycyclic aromatic hydrocarbons (PAHs). The BC was most likely ... -
Holocene Sedimentary Record from the Sunda Shelf off Peninsular Malaysia: Insights from Elemental, Isotopic and Bulk Sediment Magnetic Susceptibility Analyses
(East Carolina University, 2016-04-19)Post-Last Glacial Maximum (since ca. 20,000 cal yr BP) sediments of the Sunda Shelf (southern South China Sea) are generally thin, with the exception of incised valleys where thicker accumulations tend to occur. These ... -
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 ... -
Hurricanes May Be Good for Gulf Oil Spill, Experts Say
(East Carolina University, 2010-06-30)Part of an ongoing series on the environmental impacts of the Gulf oil spill. -
Hydrologic Dynamics in Response to Natural and Anthropogenic Stresses on a Barrier Island: Saltwater Intrusion and Inundation.
(East Carolina University, 8/5/2020)The impacts of climate change and sea-level rise on groundwater systems on barrier islands are not well documented in the literature. Globally, there is high competition for useable land in coastal regions because large ... -
Impact of Hurricane Katrina (2005) on deltaic evolution and shelf organic carbon cycling
(2010)Sediment cores from the continental shelf adjacent to the Mississippi River delta immediately after the passage of Hurricane Katrina were used to examine the magnitude, and implications for the carbon budget, of sediment ... -
The Influence of Aquaculture on Foraminifera and Sediment Properties in the Setiu Estuary and Lagoon of Terengganu, Malaysia
(East Carolina University, 2013)In order to address how aquaculture has influenced the Setiu estuary and lagoon of northeast peninsular Malaysia, foraminifera, sediment grain-size, and carbon and nitrogen isotope ratios and abundances were analyzed in ... -
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 ...
