In the middle of the ocean, because of the influence of water temperature and salinity. Seawater is also divided into several levels that are imperceptible to humans. Therefore, the ocean currents themselves are also divided into several levels that are difficult for humans to detect.

In the ocean, the surface layer of the sea water with a depth of less than 2 to 300 meters is the wind drifting layer. Wind drift occurs when the combined force of the wind stress and the horizontal turbulence stress acting on the sea surface of the planetary wind system is balanced with the geostrophic deflection force. This is the most superficial ocean current that humans have ever seen. And the ocean currents that can be used by a large number of fish and marine life are the currents of the wind drifting layer.

The magnitude and direction of the wind force of the planetary wind system vary with latitude, resulting in the convergence and divergence of sea water on the sea surface.

This convergence and divergence of seawater has two major effects: on the one hand, it causes the density of seawater to redistribute and a horizontal pressure gradient force appears, and when it is balanced with the geostrophic deflection force, a horizontal geostrophic flow is formed in a fairly thick horizontal layer.

On the other hand, at the bottom of the wind drift layer in the equatorial region, seawater flows upwards from the subsurface water or descends into the subsurface water, forming the upflow and downflow in the equatorial region.

Thermal haline effects such as freezing, ice melting, precipitation and evaporation in the ocean cause the density of seawater to be unevenly distributed over a wide area of the sea, which can cause high-density seawater to be generated on the surface of some sea areas in the polar regions and high latitudes, and sink to the deep and bottom layers.

Under the action of the horizontal pressure gradient force, the flow in the horizontal direction is the basis for the formation of submarine currents. Such submarine currents, hidden in the depths of the ocean, are not visible, but they can affect the whole world.

Deep-sea currents can also flow up to the surface through the bottom of the middle water, thus constituting a thermohaline circulation on Earth and in the oceans.

The speed of this deep ocean current can reach thousands of meters per hour. It's not fast, but it's definitely not slow. The amount of water is enormous. Therefore, the power is also extremely great. The existence in its coercion all moves with it. Nowadays, the main body is the tamamo tama pipa, and it is no exception.

And in the sea not far from Dongying, the flow of the ocean currents under the sea is faster.

There is no other reason than that here, there is the deepest trench on earth, the Mariana Trench!

The Mariana Trench is located in a zone of convergence and subduction of two tectonic plates, where the Pacific Plate subducts below the Mariana Plate. Its total length reaches 2,550 kilometers! The whole is arc-shaped. And the average width reaches 70 kilometers! The depth of the offshore engineering is about 8 kilometers on average!

The deepest point is in the Fichaz Abyss, where it is 11,034 meters deep. At the same time, it is also the deepest point of the earth.

Not long ago, a deep-sea submersible made by Chinese scientists discovered an active mud volcano on the southern slope of the Mariana Trench. Because of these volcanic activities, the creatures here are not the same as those in the shallow sea. The circulation of ocean currents here is extremely active and rapid due to the heat provided by volcanic activity.

The deepest currents are the fastest, even reaching speeds of tens of kilometers per hour!

This kind of speed makes the jade caisson well, which is already dizzy and hidden in the algae jade pipa, unable to resist at all. With the movement of this deep ocean current, he was swept into the Mariana Trench. Just like that, he fell into the endless depths of the sea.

If there are no accidents, this jade caisson will not fall. However, I don't know when I want to wake up. She was badly injured this time. Second only to the battle of the gods in ancient times. When the monks of Dongying joined forces to seal her, although she was caught off guard, she was sealed. However, he was not seriously injured. It's just that in those thousands of years, the magma has been devastationing and grinding her, which makes her feel uncomfortable.

And at the bottom of this deep sea, it is barren and lonely. The pressure on the sea is so great that volcanoes and earthquakes erupt from time to time. The environment is so harsh. If Tamakai's cultivation is to recover, it will become extremely difficult and slow. If it wakes up after thousands of years, it will be similar to being suppressed.

But just when it seemed that the jade caisson was about to sleep in this dark and cold, no light at all, a deep-sea submarine discovered the location of the jade caisson. Then, the submarine sounded an alarm sounding "Target! Target!"

This deep-sea submarine is naturally not an underwater navigation equipment made by humans. If Yun Lei was here, he should be able to recognize that this submarine was the Atlantean starship he had seen in seclusion in the deep sea when he first met Xiao Yu'er.

The crew members of this starship are not much different from the earthlings in appearance, but they are all blonde and purple-eyed, and they are tall.

After the starship spotted the algae jade lute, it stopped. The captain who commanded this starship ordered: "Execute it according to the original plan! Pour those high-grade spirit stones, as well as those spiritual liquids that were snatched from the hands of ancient cultivators, onto this algae jade pipa!"

The deputy captain next to him was reluctant: "Respected captain, this immortal cultivator, or rather, this immortal has fallen into a deep sleep now. And the algae jade pipa is also a famous innate spiritual treasure in ancient times. Why should we rescue her instead of bringing her back to base for analysis?"

"The spirit stones and spiritual liquids that the ancients snatched from the immortal cultivators are extremely precious, even if we Atlanteans can't use them for the time being, the value is very high. It is also an excellent experimental product. Isn't it a pity to hand it over to a Huaxia immortal like this?"

The captain said, "If we still have an unscathed mothership and a complete industrial system. Of course, we can take this algae jade pipa back and study it slowly. According to the level of immortal cultivators, this existence is just an ordinary immortal. When we were in our prime, we weren't afraid. ”

"But now we have an unscathed mothership, and a complete industrial system, can we trap such a powerful being? Who knows when such a being will wake up. When you wake up, what kind of revenge will you take on us?"

"The people of Atlanteis today can't stand this. Therefore, although those spiritual fluids and spirit stones are very precious, if they are of little use to us, we might as well take them out, let this existence recover and cultivate, and then return to the surface and fight the earthlings with both sides!"

"Only in this way will we have a chance to reap the benefits of the fisherman, and our plan of the Atlanteans to truly occupy the earth will be carried out. So, execute the plan, Mr. Vice Captain, and use some spirit stones and spiritual liquid that the Atlanteans can't use in exchange for a habitable planet, this investment is absolutely worth it!"
