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 ... -
Geology of the Castle Hayne Limestone in the Onslow Quarry, Richlands, NC
(East Carolina University, 2012)The Eocene age Castle Hayne Limestone Formation on the coastal plain of North Carolina is found throughout Onslow County and is mined at the Onslow quarry south of Richlands. This study characterizes the geology of the ... -
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 ... -
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 ... -
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. -
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 ... -
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 ... -
Latitudinal difference in biodiversity caused by higher tropical rate of increase
(East Carolina University, 2002-06-11)Tropical diversity has generally exceeded temperate diversity in the present and at points in the past, but whether measured differences have remained relatively constant through time has been unknown. Here we examine ... -
Macondo-1 well oil-derived polycyclic aromatic hydrocarbons
(East Carolina University, 2012-01-14)Mesozooplankton (>200 mm) collected in August and September of 2010 from the northern Gulf of Mexico show evidence of exposure to polycyclic aromatic hydrocarbons (PAHs). Multivariate statistical analysis revealed that ... -
Macondo-1 well oil-derived polycyclic aromatic hydrocarbons in mesozooplankton from the northern Gulf of Mexico
(2012)Mesozooplankton (>200 μm) collected in August and September of 2010 from the northern Gulf of Mexico show evidence of exposure to polycyclic aromatic hydrocarbons (PAHs). Multivariate statistical analysis revealed that ... -
Miocene Seismic Stratigraphy, Structural Framework, and Sea-Level Cyclicity: North Carolina Continental Shelf
(1982-12)Preliminary interpretations of over 1000 km of high-resolution seismic reflection data, supplemented by over 100 9-m vibracores, have delineated the shallow stratigraphic and structural framework for several Miocene ... -
