There seem to be two schools of thought. The most prevalent is that high methane gas levels can deplete the oxygen and kill all the sea life - that's all of the sea life. ATexas AandM University oceanography
Methane occurs naturally in sea water, but high concentrations can encourage the growth of microbes that gobble up oxygen needed by marine life.This report out of New Orleans:
At least 4.5 billion cubic feet of natural gas — and possibly almost twice that amount — have leaked since April 20. That's based on estimates from the U.S. Geological Survey's "flow team" that 2,900 cubic feet of&
"This is the most vigorous methane eruption in modern human history," said John Kessler, a Texas AandM University oceanographer.
Small microbes that live in the sea have been feeding on the oil and natural gas in the water and are consuming larger quantities of oxygen, which they need to digest food. As they draw more oxygen from the water, it creates two problems. When oxygen levels drop low enough, the breakdown of oil grinds to a halt; and as it is depleted in the water, most life can't be sustained.The second 'event' being talked about is an explosion of a methane gas bubble near the spill site so large that it ruptures the ocean floor, explodes far above the water surface, causes wide death and destruction, with tsunamis following - not to mention that the existing well-head will be obliterated:
The stretching and compression of the earth's crust causes minor cracking, called faults, and the bottom of the Gulf of Mexico has many such fault areas. Fault areas run along the Gulf of Mexico and well inland in Mexico, South and East Texas, Louisiana, Mississippi, Alabama and the extreme western Florida Panhandle. The close coupling of new fissures and cracks with natural fault areas could prove to be lethal.
A methane bubble this large -- if able to escape from under the ocean floor through fissures, cracks and fault areas -- is likely to cause a gas explosion. With the emerging evidence of fissures, the tacit fear now is this: the methane bubble may rupture the seabed and may then erupt with an explosion within the Gulf of Mexico waters. The bubble is likely to explode upwards propelled by more than 50,000 psi of pressure, bursting through the cracks and fissures of the sea floor, fracturing and rupturing miles of ocean bottom with a single extreme explosion.
The Daily Mail says a methane gas bubble actually triggered the explosion on the rig:
The Gulf of Mexico oil rig disaster was caused by a bubble of methane gas that shot oil 240ft into the air while BP executives were on board celebrating the platform’s safety record.
The highly combustible gas burst through several seals and barriers before exploding, according to interviews with rig workers conducted during BP’s internal investigation.
Workers on the Deepwater Horizon exploration rig, 50 miles off the Louisiana coast, told investigators that they set a cement seal at the bottom of the well, then attempted to put a second seal below the sea floor.
A chemical reaction caused by the setting cement created heat and a gas bubble which destroyed the seal.
Safety adviser Professor Robert Bea, of the University of California, said: ‘A small bubble becomes a really big bubble, so the expanding bubble becomes like a cannon shooting the gas into your face.’
Up on the rig, the first thing workers noticed was the sea water in the drill column suddenly shooting back at them, rocketing 240ft in the air, he said. Then gas surfaced and flooded into an adjoining room with exposed ignition sources.
‘That’s where the first explosion happened,’ said Professor Bea. ‘Then there was a series of explosions that subsequently ignited the oil that was coming from below.’
The BP executives at the party were injured but survived, according to one account.A question: If the Gulf Coast area is found to be in danger of an enormous explosion that could kill or maim the people and demolish property in the affected areas of Louisiana, Mississippi and Florida, would our Government believe it and evacuate the area? Just asking...
The following video describing the dangers of methane gas bubbles cannot be verified - at least by this blog. I don't know who is doing the talking - it sounds like a radio interview. It may be the biggest hoax in modern history, but it offers food for thought. If you have a comment about the veracity of the information, please share it with me in comments.

Government shutdown or not, there's a new $100 bill in town -- and apparently, people love it!
If Congress doesn't agree on how the U.S. will pay its bills by October 1st, the federal government will shut down. But how concerned is the average American? Not very.
Ever since President Obama's re-election back in November, the media hasn't stopped reporting about the ruffled course of the Republican party. So who's the future face of the GOP? Find out how the public voted.
New Jersey Governor Chris Christie has been at the center of media coverage for a while now. But more recently, the buzz has been about his proclaimed political party -- and whether or not he should change it.
