Scientists testing the waters in the vicinity of the Deepwater Horizon well have found massive amounts of sea life-killing methane. From Reuters:
Texas A&M University oceanography professor John Kessler, just back from a 10-day research expedition near the BP Plc oil spill in the gulf, says methane gas levels in some areas are "astonishingly high."
Kessler's crew took measurements of both surface and deep water within a 5-mile (8 kilometer) radius of BP's broken wellhead.
"There is an incredible amount of methane in there," Kessler told reporters in a telephone briefing.
In some areas, the crew of 12 scientists found concentrations that were 100,000 times higher than normal.
"We saw them approach a million times above background concentrations" in some areas, Kessler said.
Methane can fuel microbe growth that strips the water of oxygen, giving rise to "dead zones."
