The calcium supplementation plan for fisheries cannot be completed in one day. This is a phased work. The first phase will take seven days to complete, and the scope covers the entire continental shelf sea area of ????the fisheries.
The continental shelf is the natural extension of the continent to the ocean and is usually considered to be part of the land. The sea area at this location is a shallow sea zone with mostly flat terrain. The seabed is covered by sedimentary layers, which slopes from the edge to the deep sea. Finally, the land base extends into the abyssal plain.
The average water depth of the continental shelf in Daqin Fishing Ground is about 110 meters, which is a high-quality seabed terrain. The width is not the same, but it is not far apart. It ranges from 180 kilometers to 200 kilometers. The average slope is very small, only 0.2 about.
The area where calcium needs to be supplemented is this area. Except for some exposed bedrock, most of the area is covered by sediments such as mud and sand. It is fertile soil for the growth of seaweed and aquatic plants. It is also the most serious place for calcium deficiency.
The special boat operated slowly, and Qin Shiou had to follow him all the way, because he was worried that if they took the wrong path and dragged the anchor on the seabed to the coral waters, it would be in trouble.
So in addition to entertaining his father-in-law and mother-in-law these days, Qin Shiou spent the rest of the time lying on the beach and reading. Of course, this was just for acting. In fact, he was monitoring the two ships with his Poseidon consciousness.
After absorbing the 'Dragon's Fragrance' obtained from the wrist of the little old man Kauf's wife, although there was no qualitative change in Poseidon's Heart, the quantitative change was not small. His awareness of feeling the life under the sea became clearer and clearer. The impact of the ocean is also growing.
Seeing Qin Shiou lying on the beach reading every day, the fishermen looked puzzled. After Shaq went to see it, he came back and said that the boss was reading "Marine Biology". After going to see Qin Shiou, he came back and said that the captain was reading "Marine Geology". Then they discussed it and guessed that Qin Shiou was planning to enter college, right?
Last time Qin Shiou asked how to deal with the fishery to restore its former fertility. A group of fishermen were confused and couldn't come up with any nonsense. At that time, Qin Shiou was anxious and said that we lacked highly educated talents. He planned to take the marine major in a prestigious university. Master's degree study.
Qin Shiou originally said this casually, but the fishermen now took it seriously. Shaq and others also enthusiastically contacted various prestigious schools about their admissions methods.
Qin Shiou didn't know these things. He followed two ships to carefully inspect the bottom of the fishing ground these days, and found many strange things that he had not noticed before.
Since obtaining the Heart of Poseidon, Qin Shiou has controlled Poseidon¡¯s consciousness to travel through the fishing grounds almost every day.
However, it was too lonely to wander alone on the bottom of the sea. Qin Shiou didn't have the patience to stay for a long time. Instead, he liked wandering in the middle waters, because most important economic fish live in the middle waters.
With the company of two ships these days, he feels less lonely and barely has the patience to cruise around the bottom of the sea.
First of all, what Qin Shiou discovered was a submarine hot spring. These hot springs are located at the end of the continental shelf. There are several cracks on the seabed that are tens of kilometers long, and a steady stream of hot seawater emerges from here.
Qin Shiou searched and found that this kind of submarine hot springs is not uncommon on the seabed. On the contrary, it is easier to find this thing in colder seas at higher latitudes.
There are countless mysteries under the sea, and humans probably don¡¯t understand even 100% of them. For example, there is a hot spring on the seabed, but oceanographers have not studied clearly what is going on.
It is now generally accepted that the explanation is that there is crustal lava below the hot springs, and the magma that surges without breaking through the seafloor rock layers boils the water.
But what is puzzling is that many hot springs are found not in submarine volcanic zones, but in very calm areas. In addition, in the past few years, American scientific research ships have punctured the seabed where hot springs are located.
The machine has penetrated tens of meters into the earth's crust and found no 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 discovered some fine earth-like substances.
The texture of this material looks like soil, but it has different colors. In fact, it is precious seabed metal ooze.
The existence of metallic ooze is another basis for overturning the theory of hot spring magma, because not all hot springs have this kind of thing near them, only a small number of them do. Only hot springs with metallic ooze can use the hot springs with metal ooze underneath. Magma to explain.
Qin Shiou learned about it. Metal ooze is when magma from deep in the earth seeps into the formation through cracks in the seafloor crust, dissolving the salts and metals in the magma and turning it into an ore-containing solution.Under the action of deep high temperature and high pressure, the hot liquid on the seabed is sprayed to the seafloor and mixed with the deep seabed soil to form a soft mud rich in various metals.
The strategic value of this kind of soft mud is very great, but it is difficult to develop. Firstly, it is located in the deep sea. Secondly, it is surrounded by hot springs, which cannot be touched manually. Deep-sea excavation using machinery is unreliable, so this resource has been shelved.
The temperature of the hot spring is very high, but there is no lack of life around it. Qin Shiou saw some red clams, sea crabs, blood-red tubeworms, oysters, mussels, crabs, shrimps, etc. not far from the hot spring.
In addition, there are some dandelion-shaped polyps around the hot springs, as well as worms, starfish and sea anemones.
I don¡¯t know why, but the red clams and sea crabs around the hot springs are very big. I don¡¯t know if it¡¯s because no big fish likes to get close to this place. Anyway, although there are not many of them, they are big, and the most red ones are. The clam is as big as a small pot lid, which is amazing!
In addition to the hot springs, Qin Shiou discovered something even stranger, which was a large pile of glassy material!
The location of these materials is very concentrated, in a small basin in the middle of the continental shelf. Over time, the small basin has been almost covered by sea mud. This time, a special ship passed by and used an anchor to pull out these treasures.
Qin Shiou learned about it on the Internet. This glassy substance is glass. Its texture is similar to the ordinary glass produced by humans today. Its name is submarine glass.
Until now, according to people¡¯s surveys, seabed glass is only a specialty of the Atlantic Ocean. As for why so much seabed glass appears on the bottom of the Atlantic Ocean where granite is difficult to find, this is still an unsolved mystery
The small basin is not large, maybe only about 40 acres, and it is full of large pieces of seabed glass. These glasses are very similar to the silicate glass produced by people. Of course, the transparency is not that high, but it is still very impressive. The light transmittance very nice.
Moreover, these glasses are particularly gorgeous and colorful, some are light red, some are light blue, and some are snow white. It seems that someone forged the glass on the seabed and left some waste products behind.
Seeing these seabed glass, 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. Could he use these large pieces of glass to build a palace on the seabed? (Remember the website address: www.hlnovel.com
