I have to ask, what would the ramifications of this be?

Hello,

gas hydrates bind the most of the Carbon being available within the earth's outer lithosphere, sediments and atmosphere, the release of some of it would boost the already high concentration, in the atmosphere.
However no one knows what would really happen, if such a reservoir is being "hit". Some ships losses have been explained with a sudden release of CH and CO bubbles (in giant amounts) from the ocean floor, because the upwelling bubbles destroy the load-carrying capacity of water.

Rising climate temperature (speaking of 1-2 degrees Celsius) will make those buffers release their CO, thus amplifying the greenhouse effect (rising temperatures lead to more release of CO -> CO2 -> rising temperatures)

In the last few thousand years (and most probably before) gas hydrates and CaCO3 reservoirs being "trapped" underwater acted as buffers for balancing rise and fall of CO2 concentrations in the atmosphere, however the build up that took 2 million years before the Perm crisis some 300 million years ago with 98 percent of all species extinct, has now reached the peak and saturation in some 200 years. The problem is, that with current Ca available in the seas and the global temperature, the buffers are full and the CO can most probably not be withdrawn from the atmosphere any more.

An even greater risk are the gas hydrates being trapped and frozen in Sibiria on the continent, where the unfreezing of the soil would release enormous quantities of greenhouse gases.

Regarding drilling the seawater in greater depths has not the temperature to crack the chemical bond, so most probably nothing will happen. Maybe the rig will sink due to gas bubble release, but no greater release of CO2 due to the whole reservoir being unfrozen. But - nobody knows for sure.
However the "Deepwater Horizon" sank due to the fire and damage, not gas bubbles.

Greetings,

Just heard on the radio that the leak is capped.

BP is keeping a positive outlook...

“We will only succeed if we work together,” he said — a day after President Obama’s press secretary promised that the White House would “keep a boot to the throat of BP”

Quote:

Mr Hayward reiterated a promise that BP “will honour all legitimate claims for business interruption”. Asked for examples of illegitimate claims, he said: “I could give you lots of examples. This is America — come on. We’re going to have lots of illegitimate claims. We all know that.”

I know this is BP speaking but after reading this article it would seem the situation is not quite as out of control as is painted in the media.

Just one out of the three leaks but it does make capping the other two much easier according to BP.

1/3, Looking forward to see how the cone/funnel will work.

Darn, I was hoping to get annual payments if the gulf became a big pool of oil.

Thank goodness for jackbooted thugs making those evil for profit enterprises toe the line.

Two hundred years later and the damned Brits are still trying to get back at us! Just this morning I recieved a package from Jimbuna - kidney pie - an obvious attempt at mind control.

I guess it's safe to say by now that it wasn't hippie-saboteurs.

Although the incident itself is anything but funny. US of Oil has to do some serious thinking now.

SteamWake · 05-06-10, 04:25 PM

US of Oil?

I do believe other countries rely on the evils of oil as well.

Anyhow I heard today they are making addittional progress and are lowering a 4 story tall 'containment tower' over the spill site. The catch is that it is nearly a mile down and will take a couple of days to get the tower lowered and placed.

Evidently this thing is custom built, shipped out to LA and barged out to the site. Set up on a crane and started lowering in what a week? I couldent help but think to my self... some one some where is working their asses off

The first bits of oil are now starting to wash ashore. A city here in the pan handle is going to spread chopped hay to try to intercept the 'sheen' before the beach sand does.

The first images of oil soaked animals which met an untimley demise are beginning to appear.

As bad and horrible all that is I am still taken back to the statement of "The reason you havent seen coastal contamination yet is because they have done a good job at containing it at sea".

I am convinced that the hell and devistation being touted in the media is overblown. Yea I know go figure.

So someone is out there working their asses of and to me THEY are the heros here

politics, other than posturing, has little to do with it.

tater · 05-06-10, 04:33 PM

While I hope they contain this as quickly as possible, I do remind myself to use the reality check of WW2. Oil on the seas? LOL, "big fat target! Fire tubes 1, 2, 4, and 5!"

SteamWake · 05-06-10, 04:41 PM

Being a local resident here though I do share some concearns but mine is focused on the weather.

Summer is beginning to set her teeth into the region and that means a couple of things.

Trade winds will shift to predominatly SE blowing on shore.

It wil be warmer and so will the gulf waters.

Last but not least... Storms. As some know I spent alot of times in smallish boats in the gulf as well as the atlantic and I can tell you that hellacious thunderstorms can develop move in and reek havoc in a matter of minutes. I've been on a demasted or otherwise wrecked boat at least twice. One minute fair breeze next minute your dousing sail in the driving rains gale force winds with lightning snapping all around you and praying you dont get zapped while hanging on for dear life... Great fun

Won't those tend to break up and disperse the slick?

Well right now alot of the slick is evidently contained within 'booms'. Rough weather will let it out. Yea itll break up but itll collect back together again somewhere it has that nature.

Oh I forgot to add about them trying surficants and emulsifiers and all kinds of crap out there. Lets hope its not "The next Exxon Valdez"
