no linky

Here U go

Methane threads seem to not receive much attention here.

I believe the methane threat out weights the oil by far.

thanks for the update

very interesting as I am 184 miles from well head ground zero

An underwater explosion, also known as an UNDEX, is an explosion beneath the surface of water. The type of explosion may be chemical or nuclear. They are categorized in accordance with their depth beneath the water's surface, because this has a strong influence on their effects

An example of a shallow underwater explosion is the BAKER nuclear test at Bikini Atoll in July 1946, which was part of Operation Crossroads. A 20 kiloton warhead was detonated in a lagoon which was approximately 200 ft (61 m) deep. The first effect was illumination of the water because of the underwater fireball. A rapidly expanding gas bubble created a shock wave that caused an expanding ring of apparently dark water at the surface, called the slick, followed by an expanding ring of apparently white water, called the crack. A mound of water and spray, called the spray dome, formed at the water's surface which became more columnar as it rose. When the rising gas bubble broke the surface, it created a shock wave in the air as well. Water vapor in the air condensed as a result of a Prandtl-Glauert singularity, making a spherical cloud that marked the location of the shock wave. Water filling the cavity formed by the bubble caused a hollow column of water, called the chimney or plume, to rise 6,000 ft (1,800 m) in the air and break through the top of the cloud. A series of surface waves moved outwards from the center. The first wave was about 94 ft (29 m) high at 1,000 ft (300 m) from the center. Other waves followed, and at further distances some of these were higher than the first wave. For example, at 22,000 ft (6,700 m) from the center, the ninth wave was the highest at 6 ft (1.8 m). Gravity caused the column to fall to the surface and caused a cloud of mist to move outwards rapidly from the base of the column, called the base surge. The ultimate size of the base surge was 3.5 mi (5.6 km) in diameter and 1,800 ft (550 m) high. The base surge rose from the surface and merged with other products of the explosion, to form clouds which produced moderate to heavy rainfall for nearly one hour.[2]

[edit] Deep underwater explosion

The WIGWAM test, at the time of the formation of the spray domeAn example of a deep underwater explosion is the WAHOO test, which was carried out in 1958 as part of Operation Hardtack. The nuclear device was detonated at a depth of 500 ft (150 m) in deep water. There was little evidence of a fireball. The spray dome rose to a height of 900 ft (270 m). Gas from the bubble broke through the spray dome to form jets which shot out in all directions and reached heights of up to 1,700 ft (520 m). The base surge at its maximum size was 2.5 mi (4.0 km) in diameter and 1,000 ft (300 m) high.[2]

The heights of surface waves generated by deep underwater explosions are greater because more energy is delivered to the water. Deep underwater explosions are thus particularly able to damage coastal areas, because surface waves increase in height as they move over shallow water, and can flood the land beyond the shoreline.[3] Many of the theories and concepts about these waves are similar to those that are applicable to other types of surface waves, in particular, tsunamis, and waves generated by the fall of a meteor.[1]

If a deep underwater explosion occurs at a sufficient depth, the rising gas bubble can over expand because the gas pressure falls below the pressure of the surrounding water. This causes the bubble to collapse, which causes a second shock wave and bubble expansion. This may be repeated, though there are unlikely to be more than three expansions. An example is the WIGWAM test, which was carried out in 1955. The nuclear device was detonated at a depth of 2,000 ft (610 m).[2]

[edit] Other effects
The detonation of an explosive charge underwater results in an initial high-velocity shockwave through the water, in movement or displacement of the water itself and in the formation of a high-pressure bubble of high-temperature gas. This bubble expands rapidly until it either vents to the surface or until its internal pressure is exceeded by that of the water surrounding it. (The volumetric expansion of the bubble also leads to a drop in internal temperature in accordance with Charles’ Law.) At this point, as noted above, the overexpanded bubble collapses into itself, leading again to a rise in bubble pressure and internal temperature until such time as the bubble pressure exceeds water pressure. The bubble again expands, although to a rather smaller size. A second shockwave is produced by this expansion, although it will be less intense and of rather greater duration than the first. With each cycle, the bubble moves upwards until it eventually vents or dissipates into a mass of smaller bubbles. The number of cycles, while generally low, is difficult to predict; they and the overall effects, depend on explosion depth (and thus water pressure), the size and nature of the explosive charge and the presence, composition and distance of reflecting surfaces such as the seabed, surface, thermoclines, etc. This phenomenon has been extensively used in antiship warhead design since an underwater explosion (particularly one underneath a hull) can produce greater damage than an above-surface one of the same explosive size. Initial damage to a target will be caused by the first shockwave; this damage will be amplified by the subsequent physical movement of water and by the repeated secondary shockwaves or bubble pulse. Additionally, charge detonation away from the target can result in damage over a larger hull area.[4]

Oh my.

Great reply, your explanation and link were amazing

Agreed! It get zero press, it is a problem greenhouse gas (10x-20x worse than CO2) and with the amount flowing out of that well...look for a warm-up (conveniently blamed on co2).

If it starts to heat up dramatically, people will beg for cap-n-trade (nothing help the world by then, except time).

Methinks the world better hope Katla erupts!

and even New Madrid fault will be impacted...all kinds of plate activity..and more volcanoes going off as EQs rock the ground

all those containers in Georgia and elsewhere will come in very handy...

I had tried to bring awareness to the issue a few times.
In some of the links i had found - will try to dig them up later, they say that a methane feedback loop can occur.
Meaning - as Methane is released it heats the global temp.. as the global temp rises, it melts more trapped methane - and so on and so on... until you have a runaway warming event of 5-10º!

Look at the angle of the BOP under the level ROV in this view.
[link to www.bp.com] I haven't seen this view for awhile does it seem to be increasing?

yes the gas is getting into the human consciousness grid as a thread

the Gas Monster is controlled by God, btw

nada

I don't believe this shit. But then again, I have no idea if it's true or not.

"
July 2003
in this issue:

But strangely, the one generally universal indicator of gas hydrate on seismic-reflection records, a bottom-simulating reflection (BSR), is basically absent on the multitudes of seismic-reflection records from the northern gulf.

Also unusual is that mounds of gas-hydrate deposits are commonly observed on the sea floor during submersible dives, and gas hydrate, which is less dense than water, should float away.

Because drilling can bring warm fluids up from depth, potentially melting the shallower gas hydrate, many researchers and engineers anticipate that drilling through gas hydrate may pose a hazard to the stability of the well, the platform anchors, the tethers, or even entire platforms.
"

interesting.

That appears to be what is happening in areas of Siberia, where the methane-laden permafrost is exhibiting some unusual melting - and I say "unusual" because the temperaturs there have been well below zero over this past winter, and yet the permafrost is melting, which says to me that something is heating it from below. If we can remember back to previous Doom, when all the EQ's were happening in Chile is the time when this methane story was coming out - of course, people forgot about it pretty quick, but if you do a google search, there is still some info about it....

This should be pinned

how is the gas going to explode?

Or seabed floors...could not find the return signal...meaning it may well be A BOTTOMLESS PIT





They knew about this for quite a while...and they knew they were going into very dangerous turf but profit drove them way beyond any safety concerns for millions of sea life and people-


they knew it and guilty of negligence and malfeasance imho


proving it and making them pay anything near what they have robbed and ruined will be next to impossible-doesn't mean we shouldn't try-we should-and holding barry accountable on his panty waisted response

a few days back I had mentioned many ships being destroyed...and some wondered how...with a rising methane 'bubble' can readily sink a ship-RAPIDLY as well as if it(when) blows...it will take many ships with it...and the following tsunamis will bring more down...under the waters.

ice buddy, maybe its time for a long vacation in montanna. 1,184 miles would be much more better. and if your there you may as well come on up here. i am only 7 hours from great falls. bbq every night!

Added to that, a chain reaction would start events all over.

anyone else notice a distinctly "metallic" look to the "oil" that gushing on that webcam?

Might want to check this thread and the CNN Camera.
Looks Like mostly Gas of some sort now

Thread: WTF! HOLY SHIT! BP OIL WELL GUSHING OUT GAS NOT OIL!

See here is the thing your link doesn't name one geologist by name ... so I find it less than credible.

Are we talking a gradual trickle from this huge methane deposit or it all blowing at once after the seafloor collapses? If a deposit of that size was to release at once, what size tsunami would be produced?

1,100 miles+ would put him in southern Minnesota. I don't think he needs to come that far north.

All Gulf residents: LEAVE NOW: Giant Methane Gas Bubble about to Blow

I've seen these threads for over a month now, "Evacuate Florida!, from someone that lives near Pensacola Beach, Florida, may I ask a few questions...

Evacuate to where?
With what money?
What about family and friends in the same boat?
What about our homes and property?

Many of us, if we had the answers to these questions would be gone in a flash...

Unemployment in Florida is over 12% Around here, the figures are even worse. We're stuck, like Chuck.
