In a peer-reviewed article published today in Sciencexpress, an online research magazine, the scientists say the concentration of toxic constituents of oil found in the plume indicate that twice as much oil was being supplied by the wellhead to that plume than was released by all natural petroleum seeps in the northern Gulf of Mexico, which means the plume itself could not have been created by the seeps.  NOLA.com

The most worrisome part is the slow pace at which the oil is breaking down in the cold, 40-degree water, making it a long-lasting but unseen threat to vulnerable marine life, experts said.
Earlier this month, top federal officials declared the oil in the spill was mostly "gone," and it is gone in the sense you can't see it. But the chemical ingredients of the oil persist more than a half-mile beneath the surface, researchers found.
