Comparative impacts of two major hurricane seasons on the Neuse River and western Pamlico Sound ecosystems
(East Carolina University, 2004-06-22)Ecosystem-level impacts of two hurricane seasons were compared several years after the storms in the largest lagoonal estuary in the U.S., the Albemarle-Pamlico Estuarine System. A segmented linear regression flow model ... -
Comparison of quantification methods to measure fire-derived (black/elemental) carbon in soils and sediments using reference materials from soil, water, sediment and the atmosphere
(2007)Black carbon (BC), the product of incomplete combustion of fossil fuels and biomass (called elemental carbon (EC) in atmospheric sciences), was quantified in 12 different materials by 17 laboratories from different ... -
A comparison of watershed nitrogen loading and watershed nitrogen exports from on-site wastewater treatment systems and centralized sewer systems in the North Carolina Coastal Plain
(East Carolina University, 2013)Elevated nitrogen (N) concentrations in groundwater may cause adverse effects to adjacent surface water bodies. In North Carolina, half of the residences use on-site wastewater treatment systems (OWTS), yet they are typically ... -
Controls on Septic System Wastewater Treatment and Shallow Groundwater Quality in Coastal North Carolina
(East Carolina University, 2009)Excess nitrogen and bacteria concentrations in coastal waters of North Carolina have led to eutrophic conditions, fish kills, and the closure of shellfish waters. Regulatory efforts by the state to reduce nitrogen and ... -
Cyclic Deposition of Neogene Phosphorites in the Aurora Area, North Carolina, and their Possible Relationship to Global Sea-Level Fluctuations
(1982)The Neogene phosphorites in the Aurora Area occur within the Miocene Pungo River Formation (units A, B, C, and D) and the Pliocene Yorktown Formation (lower and upper units). These units are characterized by the following ... -
The Devonian West Falls Formation, implications of sedimentation controlled by preexisting structures, West Virginia
(East Carolina University, 2012)The Devonian (Frasnian) aged West Falls Formation in West Virginia contains gamma-ray signatures that have been interpreted to indicate sedimentation within a foreland (foredeep) basin. The West Falls Formation includes ... -
Diagnostic Foraminifera and Paleocology of the Pungo River Formation, Central Coastal Plain of North Carolina
(1982-12)Benthic foraminiferal assemblages of the Pungo River Formation (middle Miocene) from the central North Carolina Coastal Plain indicate deposition in continental shelf environments. In Beaufort and Pamlico Counties, part ... -
ECU aids with research of the BP oil calamity
(East Carolina University, 2010-06-16)On April 20, the explosion of the Deepwater Horizon led to a substantial oil spill catastrophe in the Gulf of Mexico. The spill caused the death of 11 people and also took a vast toll on the marine environment, suffocating ... -
ECU professors research effects of BP oil spill in Gulf of Mexico and beyond
(East Carolina University, 2010-06-08)The BP oil spill, also known as the Deepwater Horizon oil spill, has riveted the attention of the public since an explosion April 20 aboard an offshore oil rig caused crude oil to begin to leak into the Gulf of Mexico. ... -
ECU researchers discuss risky oil spill clean-up

EMPLACEMENT AND GROWTH OF LARGE COMPLEX INTRUSIONS IN THE SHALLOW CRUST, HENRY MOUNTAINS, UTAH
(East Carolina University, 2011)Details of magma migration paths in the shallow crust are poorly understood, in part because there are few locations with well-preserved contacts of igneous intrusions and surrounding host rock. The exposures in the Henry ... -
Examination of the 2011 Mississippi River Flood Deposit on the Louisiana Continental Shelf
(East Carolina University, 2014)Floods can dramatically increase the sediment load supplied to continental margins, leading to greater and potentially geochemically unique deposition. The 2011 flooding of the Mississippi River and its discharge into ... -
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 ...
