My Deep-sea Fishery

Gao Chuang also echoed at this time: "Xiang Yang, I think you can send someone down to have a look first."

Gao Chuang felt that when the fishing boat stopped, as long as the crew members wanted to go to sea, they should be allowed to go down. There was no need to make a rule that they had to go to the deck to rest within a certain period of time.

Xiang Yang continued to shake his head, "Mr. Gao, I am different from you, trawling is not my main business, and there are not many opportunities for you and your crew to go into the water.

In fact, what Xiang Yang was really worried about was naturally the crew he met.

As long as any of these crew members had an accident on the seabed, Xiang Yang's conscience would be troubled.

When Xiang Yang and the others went into the water that time, the people on the boat were not idle, one after another fishing nets were thrown into the bottom of the sea by the crew.

At this moment, the crew members who did not go into the water saw that the diving crew headed by Xiang Yang had come up from the bottom of the sea, so one by one they started to set up their nets.

The answer is naturally self-evident.

There are not many fish in this sea area at all. With so many nets, except for a little Antarctic lobster caught on each ship, there is no harvest at all.

Some were unlucky and didn't even catch Antarctic krill.

After all, the fishing nets used by everyone are not small, and Antarctic krill can easily drill out of the fishing net through the mesh.

In addition, Antarctic krill is not as easy to stick to the net as crabs, so it is not surprising that there is an empty net.

There were already enough Antarctic krill on board, so Xiang Yang ordered the crew to put the net of Antarctic krill they just caught back into the sea. In one way, it can be regarded as a restrained fishing to improve the environment.

Secondly, it is natural that Antarctic krill is not very valuable, and it is not worthwhile to drag a truck back.

Soon, time passed by every minute and every second.

Xiang Yang felt that the crew had rested enough, so he ordered: "Enough, you can continue to enter the water, it is still the same as before, you must board the boat within 30 minutes, and at the same time, after everyone enters the water, they cannot leave you to enter the water One thousand meters."

The second item was temporarily added by Xiang Yang.

Antarctica is the sea area with the most floating ice in the world, and the area of ​​the entire Antarctic floating ice city is 34 million square kilometers.

If the crew were allowed to move freely underwater, they would probably encounter very thick ice floes and be trapped and unable to get out.

In fact, although there are a lot of floating ice in Antarctica, and it can freeze every once in a while, it is the sea area with the most floating ice in the world.

But except for a small part of these floes that are really floating on the sea, most of them are huge ice bodies connected to the Antarctic continent.

Because of the existence of that line of ice, it is not easy for human beings to land on the Antarctic continent.

At the same time, because of the existence of these icebergs, Xiang Yangming ordered the pedestrians who got off the boat to rush back to the surface of the sea within 30 minutes.

After going down for a long time, it is inevitable that the water surface will freeze and be trapped to death under the water.

Although as of a few days, many scientists from different countries around the world have taken root in Antarctica, but ordinary people still cannot escape from under the ice with only a diving suit.

In addition, there are many floating icebergs in Antarctica.

There are different opinions about how the floating iceberg was formed, and Xiang Yang tends to break it.

Icebergs are mainly concentrated in the seas of the north and south poles.

Because the two polar regions receive very little solar radiation, they are cold and cold all year round.

Ice and snow cover, coupled with the accumulation of time, formed icebergs.

At first these icebergs were said to be connected to the Antarctic continent.

But later, due to the buoyancy of seawater and the impact of waves, the end of the polar continental glaciers broke off at the end of the continent, and pieces of giant ice moved along the gentle slope-shaped continent to the ocean, slowly forming glaciers.

With Xiang Yang's clear order to go into the water, all the crew members who had been looking forward to it for a long time were immediately excited.

Fang Youqun quickly put on his helmet, was the first to stand on the side of the ship, and then climbed into the sea through the hanging ladder.

Not to be outdone, the people in the back lined up and scolded Fang Youqun for being cunning.

After going down to the bottom of the sea, Xiang Yang continued to look around for traces of Antarctic deep-sea crayfish.

Suddenly, Xiang Yang stepped on something that looked like an ice cube.

"Huh?" Xiang Yang's heart moved, "This, could it be the legendary combustible ice?"

Combustible ice is a very magical energy source.

It is a kind of natural gas hydrate, which is an ice-like crystalline substance formed by natural gas and water under high-pressure and low-temperature conditions. It is called combustible ice because it looks like ice and ignites when exposed to fire.

Combustible ice is widely distributed in the deep sea or land permafrost. After burning, it only produces a small amount of carbon dioxide and water. The pollution is far less than that of coal and oil, and its reserves are huge. Therefore, it is internationally recognized as an alternative energy source for oil.

The main distribution areas of seafloor combustible ice in the world are the Gulf of Mexico in the Atlantic Ocean, the Caribbean Sea, the eastern continental margin of South America, the western continental margin of Africa, and the Black Sea Platform off the east coast of the United States.

The Bering Sea, Okhotsk Sea, Thousand Island Trench, Okinawa Trough, Japan Sea, Shikoku Trough, South my country Sea Trough, Sulawesi Sea and northern New Zealand also have very rich reserves in the western Pacific Ocean.

In addition, it is said that the Central American Trough, the Offshore California and the Peruvian Trough in the Eastern Pacific Ocean, the Gulf of Oman in the Indian Ocean, the Ross Sea and the Weddell Sea in the Antarctic, and the Barents Sea and the Beaufort Sea in the Arctic also have Significant traces of combustible ice.

Approximately 27% of the land on Earth is a potential area for the formation of gas hydrates.

About 90% of the area in the water area also belongs to such potential areas.

The gas hydrates that have been discovered mainly exist in the permafrost areas in the Arctic and in the seabed, continental slope, land base and trenches around the world. It is not surprising to find combustible ice in the Antarctic Circle.

Due to the different standards of combustible ice adopted by countries in the world, the estimates of gas hydrate reserves in the world vary greatly from different agencies.

But Xiang Yang knows that in our country, combustible ice is very important. Although oil cannot be banned by other energy sources in a short time, our country has always attached great importance to the development of new energy sources.

Coupled with the huge consumption of conventional oil and gas resources in the world, they will soon be exhausted.

According to the evaluation of combustible ice scientists, only in the seabed area, the distribution area of ​​combustible ice reaches 40 million km2, accounting for 1/4 of the total area of ​​the earth's oceans.

At present, as many as 116 combustible ice distribution areas have been discovered and announced in the world. The thickness and scale of the deposits are unmatched by conventional natural gas fields. Scientists estimate that the reserves of combustible ice on the seabed are at least enough for human consumption 1000 years.

Therefore, Xiang Yang himself also attaches great importance to the new energy source of combustible ice.
