The fight on the monthly ticket list and the recommended ticket list is very fierce, please help your brothers and sisters, eggshell must work hard to code words, and must continue to explode! ****

The first phase will take seven days to complete, covering the entire continental shelf of the entire fishing grounds.

The continental shelf is the natural extension of a continent towards the ocean and is often considered a part of the landmass. The sea at this location is a shallow sea zone, with a mostly flat terrain and a seabed covered by sedimentary layers, which start at the edge and slope towards the abyssal sea, and finally, the land base protrudes into the abyssal plain.

The average depth of the continental shelf of Daqin Fishery is about 110 meters, which belongs to the high-quality seabed topography, the width is not the same, but it is not far apart, from 180 kilometers to 200 kilometers, the average slope is very small, only about 0.2.

The place to replenish calcium is this place, where most of the area is covered by sediments such as mud and sand, except for the local exposed bedrock, which is a fertile soil for the growth of seaweed and aquatic plants, and it is also the place where calcium deficiency is most severe.

The special ship worked slowly, and Qin Shiou had to follow all the way, because he was worried that if they took the wrong way, it would be troublesome to drag the anchor towed on the bottom of the sea to the coral waters.

So in the past few days, in addition to entertaining his father-in-law and mother-in-law, Qin Shiou has been lying on the beach reading books at other times. Of course, this is only for acting, in fact, he is using the Poseidon consciousness to monitor the two ships.

After absorbing the 'Dragon Birthday Incense' obtained from the wrist of the little old man Kauf's wife, although there was no qualitative change in the heart of the sea god, the quantitative change was not small, and he felt that the consciousness of life under the sea was becoming clearer and clearer, and the impact on the ocean was also increasing.

I saw Qin Shiou lying on the beach reading a book every day. The fishermen are full of doubts, and Shaq comes back after watching it and says that the boss is watching "Marine Biology". After going to see it, the Smokegun came back and said that the captain had read "Marine Geology", and then they discussed it and guessed it. Qin Shiou is planning to go to university, right?

The last time Qin Shiou asked the fishery how to deal with it in order to restore the fertility of the past, a group of fishermen were confused and couldn't put forward their opinions, Qin Shiou was in a hurry, so he said that we lack highly educated talents, and he planned to take the master's degree in marine from a famous university.

This matter was originally said casually by Qin Shiou, but now the fishermen took it seriously, and Sha Ke and the others enthusiastically contacted the enrollment methods of various famous schools.

Qin Shiou didn't know these things, he followed the two boats to carefully check the bottom of the fishing ground these days, and found a lot of strange things that he hadn't noticed before.

Since obtaining the Heart of the Goddess. Almost every day, Qin Shiou would control the sea god's consciousness to travel through the fishing grounds.

However, wandering alone on the bottom of the sea is too lonely, Qin Shiou has no patience to stay for a long time, but he likes to wander in the middle waters, because most important economic fish live in the middle waters.

With two ships by his side these days, he is not so lonely and barely has the patience to cruise the ocean floor.

First of all, Qin Shiou discovered a submarine hydrothermal vent, which was located at the end of the continental shelf. There are several cracks on the bottom of the sea that are tens of kilometers long, and a steady stream of hot water is constantly emerging from here.

Qin Shiou searched, this kind of submarine hot spring is not uncommon on the bottom of the sea, but the higher the latitude of the cold sea area, the easier it is to find this thing.

There are still countless mysteries at the bottom of the sea. Humans probably don't know about it, for example, a hydrothermal vent on the seabed, and oceanographers haven't studied it clearly.

It is now accepted that the explanation is that there is crustal lava beneath the hydrothermal vents. It's the magma that is churning and not breaking through the rock layers on the ocean floor that boils the water.

However, it is puzzling that many of the hot springs are not located in submarine volcanic belts. It is a very calm area, and in addition, a few years ago, American research ships have punctured the seabed where the hot springs are located.

Ji qì has been going deep into the earth's crust for tens of meters without finding magma. So this explanation is a bit unreasonable.

After Qin Shiou noticed the location of this hot spring, he carefully observed the surrounding situation, and then found some delicate earth-like substances.

This material looks like dirt in texture, but it has a variety of colors, and in fact it is a precious metal ooze on the seabed.

The existence of metal ooze is another basis for overturning the theory of hot spring magma, because not all hot springs have this kind of thing nearby, only a few have it, and hot springs with metal soft mud can be explained by the presence of magma underneath.

Qin Shiou learned that metal soft mud is a kind of soft mud rich in a variety of metals formed after the deep magma of the earth seeps into the depths of the stratum along the cracks in the crust of the coastal bottom, dissolving the salts and metals in the magma into ore-containing solutions.

The strategic value of this soft mud is very large, but it is difficult to develop, one is located in the deep sea, and the other is surrounded by hot springs, which cannot be touched by artificial, and it is unreliable to use machinery for deep sea excavation, so this resource has been shelved.

The temperature of the hot spring is very high, but there is no shortage of life around, Qin Shiou saw some red clams, sea crabs, blood-red tube worms, oysters, mussels, crabs, small shrimp and so on not far from the hot spring.

In addition, there are some polyps in the shape of dandelions around the hot springs, including worms, starfish and anemones.

I don't know why, the red clams and sea crabs around the hot spring are very large, I don't know if it's because there are no big fish like to get close to this place, anyway, although they don't survive much, the top is big, and the most red clams are the size of a small pot lid, which is amazing!

In addition to the hot spring, Qin Shiou found something even stranger, that is, a large pile of glassy substance!

These materials are concentrated in a small basin in the middle of the continental shelf. The land has been long for a long time, and the small basin has been almost covered by sea mud, and this time it was a special ship passing by that it was pulled out of these treasures with an anchor.

Qin Shiou learned about it on the Internet, this glass-like substance is glass, and the texture is similar to the ordinary glass produced by human beings now, and the name is submarine glass.

Until now, according to people's investigations, submarine glass is only a specialty of the Atlantic Ocean, and it is still an unsolved mystery why so much submarine glass appeared on the bottom of the Atlantic Ocean, where granite is difficult to find......

The area of the small basin is not large, maybe only more than 40 acres, and it is full of large pieces of submarine glass, which are very similar to the silicate glass produced by people, of course, the transparency is not so high, but it is also very considerable, and the light transmittance is very good.

Moreover, these glasses are also particularly bright and colorful, some are light red, some are light blue, and some are snow white, as if someone had forged the glass at the bottom of the sea and left some scraps.

Seeing these undersea glasses, Qin Shiou suddenly thought of the Crystal Palace, the residence of the Dragon King in Journey to the West.

Thinking of the Crystal Palace, Qin Shiou suddenly had an idea, can he use these large pieces of glass to build a palace at the bottom of the sea? (To be continued......)
