Of course, even if the well is capped there's still the issue of the quarter million barrels of oil that have already leaked from the ocean floor. Or is it half a million? Experts trying to pinpoint just how much oil is loose in Gulf waters have been studying video of the gushing oil plumes in an attempt to revise BP's initial estimate of 5,000 barrels per day. Their analysis, released this morning, says we're likely looking at more like 12,000 to 19,000 barrels per day, which means that as of May 17 some 260,000 to 540,000 barrels of crude had flowed into the ocean. That means at minimum, this disaster surpassed the 1989 Exxon Valdez disaster a full ten days ago.
