Once in the Loop Current, oil can travel south and enter the Gulf Stream, a powerful ocean conveyor belt that carries warm water up the eastern seaboard.
Oil brought to Florida”s east coast could then get pulled into inlets and harbors, where it would settle into the mangrove forests that are nurseries for many species of sea life, Roffer pointed out in early May. (See pictures of ten oil-threatened animals.)
On Monday the Coast Guard reported the discovery of 20 tar balls at Key West”s Fort Zachary Taylor State Park. The sticky balls of congealed oil are currently being analyzed to determine if they came from the Gulf spill. (See pictures of tar balls and dead dolphins that washed up on Alabama beaches.)
