Tests show oil clouds drifting more than 100 miles from Deepwater Horizon site, St. Petersburg Times, June 9, 2010:
University of South Florida scientists who are working to confirm the source of the oil clouds... also had troubling news about the loop current, the warm river of water that enters the gulf from the Yucatan Peninsula and surges north into the central gulf before looping south and around the tip of Florida.Last week, they said it appeared to be reshaping, meaning it would be less likely to carry oil from the spill toward Florida and the East Coast.
That respite may be over, said USF Ocean Circulation Group director Robert Weisberg.
"Over time, there will be more oil getting into the loop current and the Florida Straits," he said. "We just have to watch."
