As BP continues to come up with schemes to slow the Gulf oil spill, new research by NPR suggests that the leak could be far worse than previously thought. Applying particle image velocimetry‚ÄĒbasically a computer program that measures the oil geyser particle by particle‚ÄĒto videos of the underwater leak, researchers concluded that the amount of oil spilling into the Gulf of Mexico could be 10 times as great as previously estimated‚ÄĒthat's 70,000 barrels a day, as opposed to 5,000. BP bases their estimates on surface measurements, saying there's no way to accurately gauge how much the flow coming out of the pipe, but they would say that. [NPR]
