The Earth Is Eating Its Own Oceans
LiveScience.com ^ | Nov 14, 2018 | Stephanie Pappas, Live Science Contributor

As Earth's tectonic plates dive beneath one another, they drag three times as much water into the planet's interior as previously thought.

Those are the results of a new paper published today (Nov. 14) in the journal Nature. Using the natural seismic rumblings of the earthquake-prone subduction zone at the Marianas trench, where the Pacific plate is sliding beneath the Philippine plate, researchers were able to estimate how much water gets incorporated into the rocks that dive deep below the surface.

The find has major ramifications for understanding Earth's deep water cycle, wrote  marine geology and geophysics researcher Donna Shillington of the Lamont-Doherty Earth Observatory at Columbia University in an op-ed accompanying the new paper. Water beneath the surface of the Earth can contribute to the development of magma and can lubricate faults, making earthquakes more likely, wrote Shillington, who was not involved in the new research.

The deep water cycle

Water is stored in the crystalline structure of minerals, Shillington wrote. The liquid gets incorporated into the Earth's crust both when brand-new, piping-hot oceanic plates form and when the same plates bend and crack as they grind under their neighbors. This latter process, called subduction, is the only way water penetrates deep into the crust and mantle, but little is known about how much water moves during the process, study leader Chen Cai of Washington University in St. Louis and his colleagues wrote in their new paper.

"Before we did this study, every researcher knew that water must be carried down by the subducting slab," Cai told Live Science. "But they just didn't know how much water."

"the team calculated that the subduction zones pull 3 billion teragrams of water into the crust every million years (a teragram is a billion kilograms)."

Isn't that = to 3,000 teragrams/year?

so the oceans resupply the deep aquifers which resupply the intermediate aquifers which resupply...etc etc etc

they’re growing, and the enviroweenies have known about it for 3 years at least:
“Their analysis, which now extends to more than 600 coral reef islands in the Pacific and Indian Oceans, indicates that about 80 percent of the islands have remained stable or increased in size ...”

So tbe oceans probably wont rise at all, but most likely drop. Given the suns cooling off more seawater will turn to ice and snow fro coldr temps, and now this fact comes out.

In a few years we will hear doom and death about falling water levels.

So globalist warning isn’t causing the ocean to rise after all

plate subduction speeds are at the rate of a few centimeters a year, so i don’t think a significant about of seawater is being carried along into the crust ...

Much more water in the crust that in all of the oceans

So all tyhe ocean water goes ‘down there’ gets sealed in and becomes super-heated.

The Earth is gonna blow like a big balloon when you stick a needle in it.

Hang on to something firm, guys. Gals, you’re on your own.

“So... The oceans are not rising, they are sinking.”

And with this we need to beat the crap out of the Climate Alarmists. Everything they have produced to prove their point that the earth is getting hotter, colder, sinking, rising, billions dead and capitalistic practices will cause the middle class to go bankrupt has been WRONG!! They cannot even tell you what will happen next week, let alone 10 years.

Just find one group of famous scientists who will get together on TV and say BULLSH*T!. And use the “everything the scientists has published over the last 20 years has been WRONG” theme.

Next week research will show the opposite is happening....

In addition to being brought down with wet sediments, water probably continually seeps through the cracks between the two plates.
