CNN has another article on the report by University of South Florida researchers, "Initial findings from a new survey of the Gulf conclude that dispersants may [may?? see following sentence] have sent the oil to the ocean floor, where it has turned up at the bottom of [Desoto] canyon within 40 miles of the Florida Panhandle."
"The dispersant is moving the oil down out of the surface and into the deeper waters" a marine microbiologist at USF told CNN.
David Hollander, a chemical oceanographer at USF, talked to CNN about shining ultraviolet lights on the ocean floor, "All of a sudden, it turns out to be a constellation of little dots."
The oil "could be eaten by fish and other animals and accumulate in the food chain," CNN reports -- the Desoto Canyon is a "spawning grounds for much of the Gulf's commercial fish."
"Small larval fish see these droplets as food so they're ingesting pure oil," said Hollander
"Organisms showed a 'strong toxic response' to the crude," USF researchers told CNN.
"The Environmental Protection Agency has previously reported some oil turning up in the sediment at the bottom of the Gulf, but has not determined whether it came from the Deepwater Horizon spill," according to CNN.
"Tests conducted offshore indicate the oil matches [BP's blowout]... the summary states," CNN adds.
