An independent scientist says the Gulf of Mexico oil spill appears to be even larger than he previously thought,
based on analysis of a video released by the Senate. The video shows a dramatic gusher of oil coming from near the well's ill-fated blowout preventer.
Steve Wereley went from being a respected but little known engineering professor at Purdue University to being the center of attention last week after he produced a startling new estimate of the size of the spill.
Using a well-established scientific technique to measure flow from the biggest of three leaks near the seafloor, he determined that the flow coming out of the end of the pipe could be 10 times the size of the official figure.
Wereley has
now analyzed video of a second leak. At a hearing on Capitol Hill on Wednesday, he said that leak alone appears to be bigger than the official estimate of 5,000 barrels a day.

Wereley's flow rate includes both gas and oil, so he says his figures may come down once he sees enough video to be able to quantify the amount of gas.
"But
from what I see in the videos, I don't see the numbers coming down that significantly," he says.

Camilli said he h
oped to use the information about oil flow to help scientists measure the magnitude of a spill that's not only on the surface of the ocean but also spreading deep underwater. "Understanding and knowing the total amount of oil that has been released is going to be critical so that we know how much was on the surface, we know how much remains subsurface, and we can track it and attempt to mitigate it."

Measuring Oil Flow
Rep. Ed Markey (D-MA) called Wereley to talk to his House Energy subcommittee after noting the huge discrepancy between Wereley's numbers and BP's oft-quoted estimate, which is based on a survey of oil on the ocean surface.
When asked Wednesday what the likelihood was that BP's figures were accurate, Wereley said he didn't see "any possibility, any scenario under which their number is accurate."
Wereley told the committee he would like clean video from BP — and lots of it — in order to sort out how much of the flow is oil versus gas and to figure out if the flow has varied since it began nearly a month ago.
BP has started to provide more video to a Senate committee. But the oil company rejected a plan that would have produced an independent measure of the oil flow.
