Didn't the Obama administration say 75% of the oil was gone?

Scientists say up to 79% of oil remains in Gulf

A group of scientists have found that up to 79% of the oil in the Gulf of Mexico may still remain, contradicting earlier findings by a U.S. government study that found nearly 75% of the oil had dissipated.

Although the new estimate is based on the same data used by the U.S. government's study, the researchers came to radically different conclusions.
