Oil in new Gulf slick matches that of 2010 spill. By Steven Mufson and Joel Achenbach. The Washington Post October 10, 2012 http://www.washingtonpost.com/business/economy/oil-in-new-gulf-slick-matches-that-of-2010-spill/2012/10/10/1f2b937c-1336-11e2-be82-c3411b7680a9_story.html[Excerpted] The oil in a slick detected in the Gulf of Mexico last month matched oil from the Deepwater Horizon spill two years ago, the Coast Guard said Wednesday night, ending one mystery and creating another.
“The exact source of the oil is unclear at this time but could be residual oil associated with the wreckage or debris left on the seabed from the Deepwater Horizon incident,” the Coast Guard said.
But Ian MacDonald, a professor of oceanography at Florida State University and a spill expert, cautioned said that the origin of the new oil remains uncertain. “The jury is out here,” he said, adding that it was too early “to rule out that this is oil freshly released from the reservoir.”
....there have been persistent rumors and allegations on blogs that Macondo is not truly dead, and that it is continuing to spew oil into the gulf.
