Study Identifies Source Of Oil Sheens Near Deepwater Horizon Site
A chemical analysis of oil sheens recently found floating at the ocean's surface near the site of the Gulf of Mexico Deepwater Horizon disaster indicates that the source is pockets of oil trapped within the wreckage of the sunken rig. First reported to the U.S. Coast Guard by British Petroleum in September, 2012, the oil sheens raised public concern that the Macondo well, which was capped in July, 2010, might be leaking. However, both the Macondo well and the natural oil seeps common to the Gulf of Mexico were confidently ruled out, according to researchers from the University of California Santa Barbara and the Woods Hole Oceanographic Institution.
