Post-Deepwater Horizon Oil Spill Study (Image 3)

February 14, 2013
Oil from the Deepwater Horizon spill is collected in booms on the sea surface, then towed away from containment and relief well operations and ignited in a controlled surface burn. This work was done by a team of researchers, led by David Valentine of the University of California, Santa Barbara, and John Kessler of Texas A&M university, that embarked on a research cruise in the Gulf of Mexico with the mission of determining the fate and impact of hydrocarbon gases that were escaping from the deep-water oil spill. The disaster provided a rare opportunity to study the behavior of methane and other natural gases in deep water. Experiments by the team were conducted as close as 1,500 feet from the epicenter of the active spill. Underwater sampling devices and sensors were used to measure hydrocarbons and oxygen depletion at various depths, and to collect water samples to study the biodegradation of natural gas and the associated blooms of bacteria. The research was funded by the National Science Foundation (grants OCE 10-42097, OCE 09-61725, and OCE 10-42650) and the Department of Energy. Credit: David L.
