Three or four large plumes have been found, at least one that is 10 miles (16 kilometers) long and a mile (1.6 kilometers) wide, said Samantha Joye, a marine science professor at the University of Georgia.
Researchers Vernon Asper and Arne Dierks said in Web posts that the plumes were "perhaps due to the deep injection of dispersants which BP has stated that they are conducting."
These researchers were also testing the effects of large amounts of subsea oil on oxygen levels in the water. The oil can deplete oxygen in the water, harming plankton and other tiny creatures that serve as food for a wide variety of sea critters.
Oxygen levels in some areas have dropped 30 percent, and should continue to drop, Joye said.
"It could take years, possibly decades, for the system to recover from an infusion of this quantity of oil and gas," Joye said. "We've never seen anything like this before. It's impossible to fathom the impact."Joye's lab was waiting for the research boat to return so a team of scientists can test about 75 water samples and 100 sediment samples gathered during the voyage. Researchers plan to go back out in about a month and sample the same areas to see if oil and oxygen levels have worsened.
One expert said BP's latest idea seems to have the best chance for success so far. Inserting a pipe into the oil gusher would be easy at the surface, said Ed Overton, a LSU professor of environmental studies. But using robots in 5,000 feet (1,500 meters) of water with oil rushing out of the pipe makes things much more difficult.
