I am just saying. Telling people that this is all ok and nothing to worry about seems a bit pre-mature.

This is a page linked to a J. M. Herndon page on the internet dealing with ultra-high levels of methane in the gulf waters.

This is a web page that has papers by J M. Herndon including a hard science paper on methane production in deep earth or created from plate tectonics.
How the ultimate BP Gulf disaster could kill millions
Disturbing evidence is mounting that something frightening is happening deep under the waters of the Gulf of Mexico—something far worse than the BP oil gusher.
Warnings were raised as long as a year before the Deepwater Horizon disaster that the area of seabed chosen by the BP geologists might be unstable, or worse, inherently dangerous.
What makes the location that Transocean chose potentially far riskier than other potential oil deposits located at other regions of the Gulf? It can be summed up with two words: methane gas.
The same methane that makes coal mining operations hazardous and leads to horrendous mining accidents deep under the earth also can present a high level of danger to certain oil exploration ventures.
Location of Deepwater Horizon oil rig was criticized
More than 12 months ago some geologists rang the warning bell that the Deepwater Horizon exploratory rig might have been erected directly over a huge underground reservoir of methane.
Documents from several years ago indicate that the subterranean geologic formation may contain the presence of a huge methane deposit.
None other than the engineer who helped lead the team to snuff the Gulf oil fires set by Saddam Hussein to slow the advance of American troops has stated that a huge underground lake of methane gas—compressed by a pressure of 100,000 pounds per square inch (psi)—could be released by BP's drilling effort to obtain the oil deposit.
Current engineering technology cannot contain gas that is pressurized to 100,000 psi.
By some geologists' estimates the methane could be a massive 15 to 20 mile toxic and explosive bubble trapped for eons under the Gulf sea floor. In their opinion, the explosive destruction of the Deepwater Horizon wellhead was an accident just waiting to happen.
Yet the disaster that followed the loss of the rig pales by comparison to the apocalyptic disaster that may come.
A cascading catastrophe
According to worried geologists, the first signs that the methane may burst its way through the bottom of the ocean would be fissures or cracks appearing on the ocean floor near the damaged well head.
Evidence of fissures opening up on the seabed have been captured by the robotic submersibles working to repair and contain the ruptured well. Smaller, independent plumes have also appeared outside the nearby radius of the bore hole itself.
According to some geological experts, BP's operations set into motion a series of events that may be irreversible. Step-by-step the drilling
Report about the Late Paleocene Thermal Maximum (LPTM), which occurred around 55 million years ago and lasted about 100,000 years. Large undersea methane caused explosions and mass extinctions.
While the entire Gulf coastline is vulnerable, the state most exposed to the fury of a supersonic wave towering 150 to 200 feet or more is Florida. The Sunshine State only averages about 100 feet above sea level with much of the coastline and lowlands and swamps near zero elevation.
A supersonic tsunami would literally sweep away everything from Miami to the panhandle in a matter of minutes. Loss of human life would be virtually instantaneous and measured in the millions. Of course the states of Texas, Louisiana, Mississippi, Alabama and southern region of Georgia—a state with no Gulf coastline—would also experience tens of thousands, if not hundreds of thousands of casualties.
Loss of property is virtually incalculable and the days of the US position as the world's superpower would be literally gone in a flash...of detonating methane.
With the emerging evidence of fissures, the quiet fear now is the methane bubble rupturing the seabed and exploding into the Gulf waters. If the bubble escapes, every ship, drilling rig and structure within the region of the bubble will instantaneously sink. All the workers, engineers, Coast Guard personnel and marine biologists measuring the oil plumes' advance will instantly perish.
As horrible as that is, what would follow is an event so potentially horrific that it equals in its fury the Indonesian tsunami that killed more than 600,000, or the destruction of Pompeii by Mt. Vesuvius.
The ultimate Gulf disaster, however, would make even those historical horrors pale by comparison. If the huge methane bubble breaches the seabed, it will erupt with an explosive fury similar to that experienced during the eruption of Mt. Saint Helens in the Pacific Northwest.
GAS COMPOSITION
Gas samples have been collected in the SW Complex from three vents and one intact piece of outcropping hydrate. Chemical analyses [1] show the vent gas to be thermogenic from deep hot source rocks and to average 95% methane, 3% ethane, 1% propane with minor other gases. There is no significant biogenic component. The outcropping hydrate is Structure II with gas composition 70% methane, 7.5% ethane, 15.9% propane with minor other gases. The difference between the gas compositions from the vents and the hydrate is due to molecular fractionation during hydrate crystallization (Sassen, pers. com.).

Please excuse my ignorance in the realm of geology, but at how many other locations other than large volcano eruptions are readings that high for any gas.

First, iyo, do you think the relief wells can handle the pressures of the gasses and oil?
I understand they will use the mud this time instead of seawater but do you think the BOP's they are going to use are capable of handling such pressures, even if they do everything right this time?
No.
Is Professor Joye concerned about these high levels of methane gasses?
Very.
Are you thinking of moving out of Florida if the relief wells fail?
I'd be planning on leaving within the next month, and that might be too late for some, regardless of what the relief wells do. Toxic fumes will be a way of life for at least the next six months to 20 years.
I set containers out yesterday to catch the rain water, to my delight, I saw no visible signs of oil.
Keep watching, but without testing, you can't tell what else is in the rainwater.

I was wondering what the results of your rain water tests are?
Thank you in advance
