Water --LOTS of it -- 400 miles beneath the surface of the U.S.?

3 times the volume of water that is in our surface oceans? If it gets out, we’ll be living (or more likely dying) in a bad Kevin Kostner movie. But 400 miles? I don’t think we have the technology to drill that deep.

New "Devil Worm" found 2.2miles below surface is Deepest-Living Animal Species evolved to withstand heat and crushing pressure. http://gnosticwarrior.com/devil-worm.html At this depth the temperature is around 55°C - 100°F Got the feeling at 400 miles deep, it would be truly hellacious ~ ~ ~

http://www.sciencemag.org/content/344/6189/1265 Dehydration melting at the top of the lower mantle Brandon Schmandt, Steven D. Jacobsen, Thorsten W. Becker, Zhenxian Liu, Kenneth G. Dueker The high water storage capacity of minerals in Earth’s mantle transition zone (410- to 660-kilometer depth) implies the possibility of a deep H2O reservoir, which could cause dehydration melting of vertically flowing mantle. We examined the effects of downwelling from the transition zone into the lower mantle with high-pressure laboratory experiments, numerical modeling, and seismic P-to-S conversions recorded by a dense seismic array in North America. In experiments, the transition of hydrous ringwoodite to perovskite and (Mg,Fe)O produces intergranular melt. Detections of abrupt decreases in seismic velocity where downwelling mantle is inferred are consistent with partial melt below 660 kilometers. These results suggest hydration of a large region of the transition zone and that dehydration melting may act to trap H2O in the transition zone.
Thanks Tim that's some interesting stuff. Nothing quite like starting the day with a new Earth appreciation discovery. :-)

I saw this story yesterday. Very interesting stuff but the deepest bore hole ever drilled was one in Russia that was started back in the 70's i believe. I was reading about this recently because a scientist was doing a thought experiment about an absolutely crazy scheme to drill to the core by splitting the earth open with billions of tons of molten iron (Earth Probe Plan Would Blast a Path to the Core]). The Russian bore hole only goes down about 12 km and they had to stop because from what I understand the rock became to plastic. The rock would slowly flow into the bore hole and they couldn't keep it open. That was only about 7 miles down so getting to 400 mile would be pretty tough unless you want to try this extreme idea they describe in the National Geographic article (originally in Nature).

And they don’t talk about the temperature in the article. Stuff like that ain’t worth reading.

I’m always suspicious of “scientific” papers that use sentences like:

These results suggest hydration of a large region of the transition zone and that dehydration melting may act to trap H2O in the transition zone.

But Jules Verne was right about an ocean at the center of the Earth. :lol: psik
