Professor Samantha Joye of the Department of Marine Sciences at the University of Georgia, who is conducting a study on a research vessel just two miles from the spill zone, said the oil has not disappeared, but is on the sea floor in a layer of scum.
"We're finding it everywhere that we've looked. The oil is not gone," Joye said. "It's in places where nobody has looked for it."
All 13 of the core samples Joye and her UGA team have collected from the bottom of the gulf are showing oil from the spill, she said.
