Gulf oil plume extends 21 miles from source - USATODAY.com: "Research out Thursday finds that the undersea oil plume from the Gulf of Mexico oil spill stretches like a cloudy tube for at least 21 miles away from where the spill happened. Reported in the journal Science, the study answers some of the questions about the fate of the crude, about 4.9 million barrels worth, in the Gulf. The size was mapped using a robot sub that plied the waters from June 19-28, when the approach of Hurricane Alex forced an end to its work before it could find an end to the plume."
