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 ... -
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 ... -
The foraminiferal signature of recent Gulf of Mexico hurricanes
(East Carolina University, 2012)Down-core activities of ⁷Be, ²³⁴Th, and ²¹⁰Pb, as well as X-radiography, have indicated the existence of sediments deposited by hurricanes Ivan (2004), Katrina (2005), and Rita (2005) on the continental margin west of the ... -
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 ...
