The WSJ is reporting that chemical dispersants worked better than previously thought in breaking up oil spilled in the Gulf of Mexico: "The updated [NOAA] report finds that of the estimated 4.9 million barrels released after the Deepwater Horizon off-shore rig exploded and sank last April, roughly 77% either was directly recovered, burned off, skimmed, dispersed or evaporated or dissolved. *** The most significant change from the August report is that government scientists have doubled the amount of oil classified as 'chemically dispersed'— from 8% in August to an estimated 16% now."
