Is there another ocean in Earth's mantle?

Heard a discussion about this
Linked article is a little old but claims to have evidence of an immense amount of water under immense pressure.
Pretty cool.
In a NASA thread we talked off hand how little we know of earth beneath us.
The deepest drilled is only seven miles. Only half way through the crust, not even to the mantle. Yet at that depth the temperature was 360° and drilling stopped.
smithsonian link, this is about borehole, other link about the water.
We really only have guesses.

The finding "confirms predictions from high-pressure laboratory experiments that a water reservoir comparable in size to all the oceans combined is hidden deep in Earth's mantle," according to an analysis of Pearson's findings by Hans Keppler of the University of Bayreuth in Germany

Yes, that’s the oceans of Middle Earth

Oceans of lava

Prehistoric monsters and shite down there.
Didn't you see at the earths core?

No?

Sorry article wasnt linked correctly.
The hypothesis is because water and a mineral formed in a diamond the idea is it means a lot of water is down there.

not likely
because PV=nRT
pressure would likely be so high that temps would exceed water's boiling point
interesting question if you consider a volume of ocean

There's a lot going on down there that science is just beginning to grasp. Do you follow Hollow Earth Theory? If not check it out, that cleared up a lot of problems I've always had with the Earth's core.

But water can also exist under immense pressure if it can't change state.
If the molecules can't expand, it'll stay water.
The vice article is crazy.

the boiling point is contingent on pressure and temperature
pressure inside of the earth is massive, so it's absolutely conceivable that there could be liquid water.

new scientist article
quote:
A reservoir of water three times the volume of all the oceans has been discovered deep beneath the Earth’s surface. The finding could help explain where Earth’s seas came from.
The water is hidden inside a blue rock called ringwoodite that lies 700 kilometres underground in the mantle, the layer of hot rock between Earth’s surface and its core.

Some people have been saying this for years.

“Since our initial report of hydrous ringwoodite, we’ve found another ringwoodite crystal, also containing water, so the evidence is now very strong,” says Pearson.
So far, Jacobsen only has evidence that the watery rock sits beneath the US. He now wants to find out if it wraps around the entire planet.
“We should be grateful for this deep reservoir,” says Jacobsen. “If it wasn’t there, it would be on the surface of the Earth, and mountain tops would be the only land poking out.”
Trying to prove that the water came from within earth.

It pisses me off that the Kardashians get reported on and not things like this.

How are the beaches? Still not as pristine as 30A.

What are these lies...? The earth is flat...

It's not the Kardashian's fault that the scientists have shitty publicists!

Just as an FYI, water's boiling point increases (or decreases) with pressure.
For example, you can boil water at a lower temperature at 10,000 feet because of reduced air pressure as compared to 0' elevation.

Well, based on that movie with Hilary Swank and two-face, the earths' core is just a big bowl of lava and diamonds.
but then based on Journey to the Center of the Earth, it looks like Jurassic Park.
So who fricking knows.
