Atmospheric Distributions of Polycyclic Aromatic Hydrocarbons (PAHs) in Coastal Northern Gulf of Mexico, USA, Associated with the Deepwater Horizon Oil Spill
Scalise, Kimberly (East Carolina University, 2013)The Deepwater Horizon (DWH) oil spill occurred April 20, 2010 to July 15, 2010, releasing a surface slick of crude oil extending to ~176,000 km² in the Gulf of Mexico (GOM). Crude oil is comprised of thousands of organic ... -

C.; Lopez-Capel, Elisa; Ding, Luyi (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 ... -
ECU aids with research of the BP oil calamity
Vyas, Shivani; Mitra, Siddhartha; Patel, Nidhi (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
Mitra, Siddhartha; Kimmel, David G.; Hutson, Jeannine Manning (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. ... -

Holocene Climate and Carbon Sequestration via Black Carbon Burial in Sediments
Patel, Nidhi (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 ... -
A Holocene record of climate-driven shifts in coastal carbon sequestration
Mitra, Siddhartha; Zimmerman, Andrew R.; Hunsinger, Glendon B.; Willard, Debra; Dunn, Joshua C. (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 ... -
Impact of Hurricane Katrina (2005) on deltaic evolution and shelf organic carbon cycling
Allison, M.A.; Dellapenna, T.M.; Gordon, Elizabeth S.; Mitra, Siddhartha; Petsch, S.T. (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 ... -

Oceanic loading of wildfire-derived organic compounds from a small mountainous river
Hunsinger, Glendon B.; Mitra, Siddhartha; Warrick, Jonathan A.; Alexander, Clark R. (2008)Small mountainous rivers (SMRs) export substantial amounts of sediment into the world's oceans. The concomitant yield of organic carbon (OC) associated with this class of rivers has also been shown to be significant and ... -
Sorption of Ibuprofen to Coastal Plain Soils
Benfield, Beau D (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, ... -
