This undated handout photo provided by Samantha Joye, UGA Department of Marine Sciences, shows a layer of oil on a sediment core. Researchers are finding oil dripping "all over the place" on the Gulf of Mexico sea floor, some as much as two inches thick. A University of Georgia scientific cruise is collecting at least ten instances of what appears to be fresh oil on the sea floor emanating out from the site of BP oil rig disaster.
