Scientists worry current could carry oil to Keys

With BP finally gaining some control over the amount of oil spewing into the Gulf of Mexico, scientists are increasingly worried that huge plumes of crude already spilled could get caught in a current that would carry the mess all the way to the Florida Keys and beyond, damaging coral reefs and killing wildlife.

Scientists said the oil will move into the so-called loop current soon if it hasn't already, though they could not say exactly when or how much there would be. Once it is in the loop, it could take 10 days or longer to reach the Keys.

"It's only a question of when," said Peter Ortner, a University of Miami oceanographer.

In the month since an offshore drilling platform exploded, killing 11 workers, BP has struggled to stop the leak, trying in vain to activate emergency valves and lowering a 100-ton box that got clogged with icy crystals. Over the weekend, the oil company finally succeeded in using a stopper-and-tube combination to siphon some of the gushing oil into a tanker, but millions of gallons are already in the Gulf.

The loop current is a ribbon of warm water that begins in the Gulf of Mexico and wraps around Florida. Some scientists project the current will draw the crude through the Keys and then up Florida's Atlantic Coast, where the oil might avoid the beaches of Miami and Fort Lauderdale but could wash up around Palm Beach.

Many scientists expect the oil to get no farther north than Cape Canaveral, midway up the coast, before it is carried out to sea and becomes more and more diluted.
