Indeed. This old news (2014) of "Huge Underground Ocean" Discovered Towards Earth's Core" in ringwoodite "When a rock with a lot of H2O moves from the transition zone to the lower mantle it needs to get rid of the H2O somehow, so it melts a little bit," Schmandt said. "This is called dehydration melting.” After the rock melts, the researchers say, the water becomes trapped in the transition zone, creating a reservoir" under great pressure is not opposed to conditions of the ancient earth of Noah' s day in which "In the six hundredth year of Noah’s life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.

That settles it!
Hurrah! Scientists have discovered something that is not necessarily in opposition to Biblical truth!
What a great argument to bolster one's own faith, or to convince doubters!

I can only repeat: Overwought interpretations of half-understood scientific papers providing weak support for or at least not outright opposing established Biblical doctrines are of little to no use to anyone - and they represent a snare for people of faith.
