excerpt - "There are five oceans on Earth: the Atlantic, Pacific, Indian, Arctic, and Southern Ocean. An international team of scientists has now found evidence of considerable quantities of water between the Earth’s upper and lower mantle. The evidence was found during the analysis of a rare diamond that formed 660 kilometers below the Earth’s surface confirming the theory that ocean water accompanies subducting slabs and thus enters the transition zone. The new findings reveal that Earth's water cycle includes the Earth’s interior. The study by the German-Italian-American research team has been published in the journal Nature, which states that the internal structure and dynamics of Earth have been shaped by the 660km boundary between the mantle transition zone and the lower mantle. WHERE IS THE SIXTH OCEAN? The evidence points to water in the transition zone (TZ), the boundary layer that separates the Earth’s upper mantle and the lower mantle. The boundary is located at a depth of 410 to 660 kilometers, where immense pressure of up to 23,000 bar causes the olive-green mineral olivine to alter its crystalline structure. Olivine constitutes around 70 percent of the Earth’s upper mantle and is also called peridot. Researchers said that at the upper boundary of the transition zone, at a depth of about 410 kilometers, it is converted into denser wadsleyite; at 520 kilometers it then metamorphoses into even denser ringwoodite. “These mineral transformations greatly hinder the movements of rock in the mantle. Subducting plates often have difficulty breaking through the entire transition zone. So, there is a whole graveyard of such plates in this zone underneath Europe,” explains Prof. Frank Brenker from the Institute for Geosciences at Goethe University." (Note: the "Ocean" is hydrous rock. It's like a wet sponge.) |

I've been trying to warn yall about the reptoids who live in caves and shit underground but yall just think I'm crazy

It's a once in a lifetime discovery.

Make sure you turn off the tap or all the Earth's water will magically disappear, even in New Yawk which is right next to a body of... Water!

How will this impact the 35 mile diameter glob of fresh water?

I don't think I've ever seen a reptile that can't swim. There's one lizard that runs across water. They're well equipped for aquatic activities |

This is not news. We have known for decades that subducted plates carry a LOT of water with them. The water actually lowers the melting temperature of rock, which is one of the primary reasons that subduction zones are characterized by lots of volcanic activity (see: Ring of Fire.)

It might be an ocean in scale, probably a small ocean at that, but it's just the water that gets subducted with the crust, which we've known about for a long time. It's kind of cool that the pressure and temperature gradients result in liquid water at certain depths though.
