The weather changed yesterday and kept the Gulf of Mexico oil spill off the Louisiana coast for at least another day. But while we previously reported on the damage that oil could do if it makes landfall, there could also be disastrous consequences if the oil heads too far in the other direction, out to sea. Not far south of the oil slick's present location lies the Gulf loop current, which heads north from Mexico's Yucatan Peninsula, makes a sharp turn in the middle of the Gulf and then heads for the tip of Florida. Eventually, water caught in the current can get pushed around to Florida and then connect to the Gulf Stream current.
Oceanographer George Maul worries that the current could push the oil slick right through the Florida Keys and its 6,000 coral reefs.
