Scientists find huge oil plumes deep in Gulf of Mexico: report

Scientists have discovered enormous plumes of oil in the deep waters of the Gulf of Mexico, in an indication that the leak from an underwater well could be far worse than previously estimated, The New York Times reported late Saturday.
One of the plumes was 10 miles (16 kilometers) long, three miles wide and 300 feet (91 meters) thick, according to the newspaper.
The BP-leased Deepwater Horizon oil rig exploded and sank in the gulf last month, rupturing a riser pipe that has been spewing hundreds of thousands of gallons of crude into the sea each day.
"There's a shocking amount of oil in the deep water, relative to what you see in the surface water," the Times quoted University of Georgia researcher Samantha Joye as saying.
"There's a tremendous amount of oil in multiple layers, three or four or five layers deep in the water column."
Joye is involved in one of the first scientific missions to gather details about the environmental disaster.
The plumes are depleting the oxygen in the gulf, prompting fears that the process could eventually kill much of the sea life near the plumes, the report said.
Joye said the oxygen had already dropped 30 percent near some of the plumes.
"If you keep those kinds of rates up, you could draw the oxygen down to very low levels that are dangerous to animals in a couple of months," she is quoted as saying. "That is alarming."
The oil plumes were discovered by scientists from several universities working aboard the research vessel Pelican, which sailed from Cocodrie, Louisiana, on May 3, the Times said.
Studying video of the gushing oil well, the scientists have tentatively calculated that it could be flowing at a rate of 25,000 to 80,000 barrels of oil a day, the paper noted, up to 16 times the rate of 5,000 barrels a day estimated earlier by US officials and BP.

I doubt a conventional nuclear weapon can handle the depth in its standard package. Even a convention depth charge would probably crushed. Either weapon would have to be placed in pressure vessel, steered to tgt and remotely detonated. Not saying it could not be done, but I don't think it is easy as it sounds at 160 atms per sq in pressure.

Just in case anyone took that as being true, let me explain. The oil and gas that is floating through the water column reacts directly with the oxygen in the water. The result is carbon dioxide and water vapor. The reason that you still have oil left is that it overwhelms the small partial pressure of oxygen at those depths. The result is that all life that relies on oxygen (including some of the bacteria (some do not need oxygen) you think are metabolizing the oil) dies. In lower concentrations the bacteria would be able to feast on the oil. However, in the plumes from this spill the oil overwhelms the oxygen and the biota. The result is suffocating marine life.

Consideration of the portability of these demolitions devices led many to conclude that genuine adversaries would have no problems in locating them at strategic locations in large cities and near military locations, within their enemys' borders. This would provide genuine mutual assured destruction and deterrance, and sheds further doubt on there being any real threat of nuclear engagement during the 'cold war'. Why build all those missiles when you both had these things stashed, secure and undetectable, in the heart of enemy territory?
We can conclude that there were no 'enemies' other than the great mass of humanity itself at the time, and that this adversarial arrangement was used to enable the orderly division of this mass for the Purpose of managing them.

To help clarify, the main difference is whether or not it is in essence free product/NAPL or a dissolved plume. If the concentration is to the point of free product, bacteria will be ineffective. If it is in essence a dissolved plume, like your usual seafloor releases, bacteria handle it pretty well. The more concentrated, the longer it takes bacteria to break it down as well, so its not a quick fix and in either case you will be removing oxygen.
Once the source is removed, it'll still be a massive work to disperse/break down/remove the oil, and hopefully well enough that damage to the ecology is minimized.

The result was not perfect. 1 in 6 did not work. Nor the application easy to do. Engineers, no matter how talented or well meaning are not gods. They have to work within their knowledge and technological limits. In one instance, they have to detonate a nuke 6km underground (~18,000ft). That was a well on dry land. Imagine you have to put the nuke down 1.5 mile of water + 18,000 ft hole. May as well drill the relief well and kill the leak the usual way.

Yep that was my point. There are 264 gallons in a cubic meter (about 6.29 barrels). 6.29*75 million = 471.75 million barrels of oil, divided by 25 days it took to form the plume = 18 million barrels of oil a day, give or take. not counting the other plumes or surface slick. Either it's not true, or the "leak" is way worse than even the worst-case estimates.

You have to take into account that the plumes are not 100% oil by volume. They are an emulsion of oil in water, with most of the volume still taken up by water. Once you account for the dilution, the numbers shrink quite a bit. Of course, it's hard to account for dilution when we don't have the relevant numbers available...

Now, something really doesn't add up, because these numbers indicate a flow rate in excess of 1 million barrels per hour, or about 280 barrels per second (and that's not counting gas.) To dispense such volumes through a narrow borehole, the flow would have to be supersonic.
18+ million barrels/day is about 40 times the flow-based estimates of ~50,000 barrels/day. Of course, one possibility is that dilution levels in the plumes are not 100:1, but about 1/40th of that -- more like 25,000:1 (or just 250 ppm), though that sounds awfully thin...

In '79 I believe there was a similiar oil spill that actually dumped 140 million gallons into the gulf by the time it was done. The major difference was that it was much further off shore, and the oil was ejected by the currents into the atlantic.
Due to the currents is why your getting what probably looks alot like a upside down chlorinated solvent plume. Fragmented and scattered.
But if it is diluted or basically a dissolved plume, then organisms can handle it especially if it stays off shore. The limiting agent is not oxygen, thatll be in plenty supply. It's the lack of phosphorus ultimately, but also nitrogen.

It appears that BP is very much to blame, Transocean(Corp HQ Swiss), and Halliburton also get a piece of the pie.
Also, it should be pointed out that this oil is in a reservoir not only under 5,000ft of water, but also ~20,000 ft of crust. Resulting combined litho- and hydrostatic pressure is many thousands of tons per square inch- I would venture a more exact figure, but it's a long time since I studied the quantitative aspects of geology. At any rate, it would, uncontrolled, result in quite a vigorous, high-volume flow rate, even given relatively small aperture.

Will the yield be sufficient to collapse the hole below the sediment layer? Will collapsing the rock layer seal the leak, or cause a thousand smaller ones?
Blithely ignoring worst-case scenarios is what caused this disaster. Shall we repeat that mistake on a larger scale?
