(East Carolina University, 2019-10-02)ABSTRACT GROUNDWATER FLOW IN THE UPPER CASTLE HAYNE AQUIFER: NUMERICAL SIMULATIONS AND STRONTIUM ISOTOPIC INVESTIGATIONS by Samantha Eileen Kofroth August 2019 Director of Thesis: Dr. Terri L. Woods Major Department: ... -
IRON ISOTOPE GEOCHEMISTRY OF BULK ROCKS AND Fe-Ti OXIDES FROM THE SKAERGAARD LAYERED MAFIC INTRUSION, SE GREENLAND
(East Carolina University, 2019-07-23)Small, but significant fractionation of Fe isotopes occurs in high-temperature igneous rocks. Despite increasing study, the exact causes of this fractionation are still debated. Therefore, a systematic study of a complete ... -
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 ... -
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 ... -
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 ... -
GEOLOGY AND ORIGIN OF SAND RIDGES IN A BACK-BARRIER ESTUARY, PAMLICO SOUND, NORTH CAROLINA
(East Carolina University, 2018-06-06)The Outer Banks of North Carolina have undergone significant geomorphic change, exhibiting varying degrees of barrier island continuity during the late Holocene. These changes affect the environmental conditions (salinity, ... -
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 ... -
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 ... -
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 ... -
Sorption of Ibuprofen to Coastal Plain Soils
(East Carolina University, 2017-07-18)The transport and fate of pharmaceuticals and personal care products (PPCPs) in terrestrial and aquatic ecosystems has become an area of concern in the environmental science community. Due to advances in analytical technology, ... -
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 ... -
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 ... -
Nearshore mixing and nutrient delivery along the western Antarctic Peninsula
(2017)The surface waters of the Southern Ocean play a key role in the global climate and carbon cycles by promoting growth of some of the world’s largest phytoplankton blooms. Several studies have emphasized the importance of ... -
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 ... -
Morphology, Geologic History and Dynamics of Wimble Shoals, Rodanthe, NC
