"BP Spill Left Big Oily 'Bathtub Ring' on Seafloor"

"WASHINGTON — The BP oil spill left an oily "bathub ring" on the sea floor that's about the size of Rhode Island, new research shows.

The study by David Valentine, the chief scientist on the federal damage assessment research ships, estimates that about 10 million gallons of oil coagulated on the floor of the Gulf of Mexico around the damaged Deepwater Horizons oil rig.

Valentine, a geochemistry professor at the University of California Santa Barbara, said the spill from the Macondo well left other splotches containing even more oil. He said it is obvious where the oil is from, even though there were no chemical signature tests because over time the oil has degraded."
