Staunching the bleeding.

Personally, I think his persuasive powers are overrated, but wouldn't it be wonderful if President Obama had a track record for bringing together all factions to solve problems?

Never mind the finger pointing -- plenty of time for that -- now is the time to come together, and solicit help from the Saudis and worldwide if needed, to drill the emergency well to relieve pressure from the leaking. "Top hats" and caps are just for show, short term. And BP is still in the director's chair, directing cleanup efforts? Hm... it is wise to put the mess-maker in charge of the cleanup, or do they have incentive to minimize or hide the damage?

This oil spill is an excellent example of what's happening in America today. Our brightest and best-known minds are good at ... talking. Debating. Finessing the rules. Bringing people together. But that doesn't seem to stop either blood or oil from spilling.

We don't excel at science and technology -- who cares?; we buy those goodies. And we don't understand such common-sense reality as: If it's spilling, it's going somewhere folks and affecting the ecology. Whether you see it or not.

Scientists are finding enormous oil plumes in the deep waters of the Gulf of Mexico, including one as large as 10 miles long, 3 miles wide and 300 feet thick in spots. The discovery is fresh evidence that the leak from the broken undersea well could be substantially worse than estimates that the government and BP have given.

“There’s a shocking amount of oil in the deep water, relative to what you see in the surface water,” said Samantha Joye, a researcher at the University of Georgia who is involved in one of the first scientific missions to gather details about what is happening in the gulf. “There’s a tremendous amount of oil in multiple layers, three or four or five layers deep in the water column.”

The plumes are depleting the oxygen dissolved in the gulf, worrying scientists, who fear that the oxygen level could eventually fall so low as to kill off much of the sea life near the plumes.

Scientists studying video of the gushing oil well have tentatively calculated that it could be flowing at a rate of 25,000 to 80,000 barrels of oil a day. The latter figure would be 3.4 million gallons a day. But the government, working from satellite images of the ocean surface, has calculated a flow rate of only 5,000 barrels a day.

BP has resisted entreaties from scientists that they be allowed to use sophisticated instruments at the ocean floor that would give a far more accurate picture of how much oil is really gushing from the well.

The undersea plumes may go a long way toward explaining the discrepancy between the flow estimates, suggesting that much of the oil emerging from the well could be lingering far below the sea surface.

The scientists on the Pelican mission, which is backed by the National Oceanic and Atmospheric Administration, the federal agency that monitors the health of the oceans, are not certain why that would be. They say they suspect the heavy use of chemical dispersants, which BP has injected into the stream of oil emerging from the well, may have broken the oil up into droplets too small to rise rapidly.

BP said Saturday at a briefing in Robert, La., that it had resumed undersea application of dispersants, after winning Environmental Protection Agency approval the day before.

“It appears that the application of the subsea dispersant is actually working,” Doug Suttles, BP’s chief operating officer for exploration and production, said Saturday. “The oil in the immediate vicinity of the well and the ships and rigs working in the area is diminished from previous observations.”

Many scientists had hoped the dispersants would cause oil droplets to spread so widely that they would be less of a problem in any one place. If it turns out that is not happening, the strategy could come under greater scrutiny. Dispersants have never been used in an oil leak of this size a mile under the ocean, and their effects at such depth are largely unknown.
