The ocean on Earth is being sucked into a place where no one knows where it is

The ocean is not just what we see. In the deep sea there are still separate flows, it can even be considered as a form

Deep sea water is being sucked down to the bottom of the sea. But specifically where they go, no one knows.

The ocean is not just what we see. In the deep sea there are still separate currents, it can even be considered a "sea" form different from what is experienced on the water.

And while the sea water was gradually rising due to the melting of the ice, the water at the bottom was actually sucked. Where they flow, no one knows, only that it is the result of collisions of tectonic plates. In other words, the water is being sucked down to the ground, called the "subduction zone" .

The submersible suction rate is measured about a few centimeters a year.

Subduction is a concept of geology, taking place at the convergent boundaries of moving arrays, in which an array sinks down the remaining array, creating a suction effect.

The submersible suction rate is measured about a few centimeters a year. However, according to a recent study, the rate of water absorption is higher than what has been calculated 3 times in advance by science.

"People still know that submerged areas can absorb water, but it's unclear how much water is" - Chen Cai, PhD thesis author at Washington University (St. Louis).

Candace Major, director of the Ocean Science program at the National Science Foundation, said: "But this study shows that submerged regions actually draw more water to the deepest layers of the Earth than previously thought. that".

"Research results underscore the importance of submerged areas for ocean flows."

The world is majestic under the ocean

To carry out this study, experts had to spend more than a year to "listen" . The sounds they hear are vibrations from earthquakes, from collisions of tectonic plates under the Mariana basin (the deepest gulf in the world under the ocean). They used 19 seismic recorders in this area, along with 7 recorders in neighboring islands.

The Mariana Area is also the boundary between the Pacific tectonic plate that slides up on the Mariana Plate, forming a submerged zone.

Previous studies have shown that the area can retain water, but do not know how much it is, and how deep they can be. In other words, how much water is sucked down, no one knows.

"Previous calculations are based on available data - that is only 6.4 km deep under tectonic plates," Cai said.

"That method cannot tell exactly the thickness of the array and its water absorption ability."

"Our research tries to solve this question. If the water goes deeper, they can stay there, or even continue to go deeper."

The data show that the "boisterous" rock floor of the Mariana slot spreads up to 36km on the sea floor - deeper than we thought it was extremely much.

Already down is right up

Particularly, the water area being sucked down is larger than the previous calculation up to 4 times. Researchers can also from here learn about similar areas around the world.

"If other subduction areas are similar in nature, then the calculations may differ by up to three times," said Douglas A. Wiens, professor of thesis for Cai.

However, this does not mean that the water level on Earth will decrease.The water that has been sucked down will rise, and the sea level up to now is still stable. That is, the amount of water that falls into the subduction zone will escape at a certain time, but not be fully absorbed into the soil.

The water that has been drawn down will rise and the sea level is still stable.

Scientists had previously believed that most of the water drained into the trench would return as steam, because volcanoes operate a few hundred miles away. But through research, they realized that the amount of water entering the ground seemed far beyond the amount of water returned.

"The calculation of water intake through volcanic activity is really uncertain" - Wiens shared. Research will need to be reevaluated.

This is also normal, because the calculation of the water cycle in the world is difficult to reach the correct threshold.

Recently, Professor Wiens applied the same type of geological activity calculation to the Mariana trench, but off the coast of Alaska - also an area with submerged areas.

"Is there any difference in the amount of water absorbed at other subduction areas, based on the shape of the tectonic plates?" - Wiens asked questions.

The study is published in Nature.
