November 16, 2020 Former piece of Pacific Ocean floor imaged deep beneath China

[S]eismic researchers have discovered the underside of a rocky slab of Earth's surface layer, or lithosphere, that has been pulled more than 400 miles beneath northeastern China by the process of tectonic subduction.

The study, published by a team of Chinese and U.S. researchers in Nature Geoscience, offers news evidence about what happens to water-rich oceanic tectonic plates as they are drawn through Earth's mantle beneath continents.

Rice University seismologist Fenglin Niu, a co-corresponding author, said the study provides the first high-resolution seismic images of the top and bottom boundaries of a rocky, or lithospheric, tectonic plate within a key region known as the mantle transition zone, which starts about 254 miles (410 kilometers) below Earth's surface and extends to about 410 miles (660 kilometers).

Earth's mantle convects like heat in an oven. Heat from Earth's core rises through the mantle at the center of oceans, where tectonic plates form. From there, heat flows through the mantle, cooling as it moves toward continents, where it drops back toward the core to collect more heat, rise and complete the convective circle.

Previous studies have probed the boundaries of subducting slabs in the mantle, but few have looked deeper than 125 miles (200 kilometers) and none with the resolution of the current study, which used more than 67,000 measurements collected from 313 regional seismic stations in northeastern China. That work, which was done in collaboration with the China Earthquake Administration, was led by co-corresponding author Qi-Fu Chen from the Chinese Academy of Sciences.

Mantle convection drives the movements of Earth's tectonic plates, rigid interlocked pieces of Earth's surface that are in constant motion as they float atop the asthenosphere, the topmost mantle layer and the most fluid part of the inner planet.

I can only assume this means the chinese own the Pacific ocean.

So China is hording tectonic plates now?

I say this cannot stand, sir.

I still have problems believing this:

‘Underground Oceans’ Potentially Have 3 Times More Water Than Surface - Study

It's the source of the "Fountains of the deep" from the Book of Genesis.

Earth doesn't have sufficient surface water (from rainfall and melting icecaps) to fully inundate the earth. To cover the highest mountaintops would require an additional 3 - 4 ocean's worth of water. It looks like they found it.

"Heat drops back to the core were it collects more heat?" Check. Got it. Does anybody proof-read this stuff anymore?

Misuse of quotation marks noted.

Curious if that convective core heat is accounted for in global warming calculations...

Only if pre-flood geography had mountain ranges the same height as post-flood.

Better yet - here are the video explanations of hydroplate theory:

Or maybe the hydroplate theory is what needs to be accounted for:
