Gao Chuang also agreed at this time: "Xiang Yang, I think you can send someone down to take a look first."
Gao Chuang felt that when the fishing boat stopped, as long as the crew wanted to go to the sea, they could just go down. There was no need to make a rule that required them to go on deck to rest within a certain period of time.
Xiang Yang continued to shake his head, “Boss Gao, I am different from you. Trawl is not my main business, and you and your crew don’t have many opportunities to go into the water.
In fact, what Xiang Yang was really worried about was the crew he met.
Xiang Yang would feel guilty if any of these crew members encountered any accident on the seabed.
When Xiang Yang and his crew went into the water, the people on the boat were also busy. One fishing net after another was thrown into the sea by the crew.
At this moment, the crew members of the fleet who had not entered the water saw that the crew members led by Xiang Yang who had dived into the water had come up from the bottom of the sea, so they began to raise their nets one after another.
The answer is naturally self-evident.
There are not many fish in this sea area. Even with so many nets, the ships didn't get anything except a few Antarctic lobsters.
Some of the unlucky ones didn't even catch Antarctic krill.
After all, the fishing nets that everyone uses have large meshes, and Antarctic krill can easily pass through the meshes and get out of the fishing nets.
In addition, Antarctic krill are not as easy to get stuck in the net as crabs, so it is not surprising that there are empty nets.
There were already enough Antarctic krill on the boat, so Xiang Yang ordered the crew to release the Antarctic krill they had just caught back into the sea. On the one hand, this could be considered as restrained fishing and would improve the environment.
Secondly, Antarctic krill are of course not very valuable, and hauling a truckload back is not cost-effective at all.
Soon, time passed by minute by minute.
Xiang Yang felt that the crew had rested enough, so he gave the order: "That's enough, you can continue to go into the water. Just like before, you must be on the boat within 30 minutes. At the same time, after everyone goes into the water, they cannot leave your launching point within one thousand meters."
The second item was added temporarily by Xiang Yang.
Antarctica is the sea area with the largest amount of floating ice in the world. The total area of floating ice in Antarctica is 34 million square kilometers.
If the crew were allowed to move freely underwater, they would most likely encounter very thick ice floes and be trapped.
In fact, although there is a lot of floating ice in Antarctica, it freezes every once in a while and is the sea area with the most floating ice in the world.
But except for a small part of these floating ice that are actually drifting on the sea, most of them are huge ice bodies connected to the Antarctic continent.
It is precisely because of the existence of that line of ice that it is not easy for humans to land on the Antarctic continent.
At the same time, because of the existence of these icebergs, Xiang Yangming ordered the people who got off the ship to return to the sea within 30 minutes.
If you stay down there for too long, it is inevitable that you will encounter ice on the water surface and be trapped to death underwater.
Although as of a few days ago, many scientists from different countries around the world have settled in Antarctica, ordinary people still cannot escape from under the ice with just a diving suit.
In addition, there are many floating icebergs in Antarctica.
There are many different opinions about how the row of floating icebergs were formed, and Xiang Yang is more inclined to the theory of fracture.
Icebergs are mainly concentrated in the waters of the North and South Poles.
Because the two polar regions receive very little solar radiation, they are cold and low all year round.
Ice and snow cover the ground over time and accumulate to form icebergs.
Initially these icebergs were said to be connected to the Antarctic continent.
But later, the end of the polar continental glacier broke due to the buoyancy of sea water and wave impact, and huge pieces of ice moved along the gently sloping continent to the ocean, slowly forming glaciers.
As Xiang Yang gave the clear order to go into the water, the crew members who had been looking forward to it for a long time suddenly became 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 ladder.
The people behind were not willing to be outdone. While queuing up, they cursed Fang Youqun for being cunning.
After going down to the bottom of the sea, Xiang Yang continued to look for traces of the Antarctic deep-sea crayfish.
Suddenly, Xiang Yang stepped on something that looked like ice.
"Hmm?" Xiang Yang's heart moved, "Could this be the legendary combustible ice?"
Methane hydrate is a very magical energy source.
It is a natural gas hydrate, an ice-like crystalline substance formed by natural gas and water under high pressure and low temperature conditions. Because it looks like ice and burns when exposed to fire, it is called combustible ice.
Methane hydrate is widely distributed in the deep sea or permafrost on land. After burning, it only produces a small amount of carbon dioxide and water. The pollution is far less than coal, oil, etc., and its reserves are huge. Therefore, it is internationally recognized as the successor energy source to oil.
The main distribution areas where seabed methane hydrate has been discovered in the world are the Gulf of Mexico in the Atlantic Ocean, the Caribbean Sea, the eastern margin of South America, the western margin of Africa, and the Blake Plateau off the east coast of the United States.
The Bering Sea, Sea of Okhotsk, Kuril Trench, Okinawa Trough, Sea of Japan, Shikoku Trough, South my country Sea Trough, Sulawesi Sea and northern waters of New Zealand in the western Pacific also have very rich reserves.
In addition, it is said that there are large amounts of methane hydrate in the Central American Trough, California Offshore and Peruvian Troughs in the eastern Pacific Ocean, the Gulf of Oman in the Indian Ocean, the Ross Sea and Weddell Sea in Antarctica, and the Barents Sea and Beaufort Sea in the Arctic.
Approximately 27% of the land on Earth is a potential area for the formation of natural gas hydrates.
About 90% of the water area is also such a potential area.
The discovered natural gas hydrates mainly exist in the permafrost areas of the Arctic region and on the seabed, continental slopes, land bases and trenches around the world. It is not surprising at all to find combustible ice in the Antarctic Circle.
Because different countries around the world adopt different standards for methane hydrate, different institutions' estimates of the world's natural gas hydrate reserves vary greatly.
But Xiang Yang knew that in my country, combustible ice is given great importance. Although oil is unlikely to be replaced by other energy sources in a short period of time, my country has always attached great importance to the development of new energy.
In addition, the world's conventional oil and natural gas resources are being consumed at a huge rate and will soon be exhausted.
After evaluation by combustible ice scientists, it was determined that the distribution area of combustible ice in the seabed alone is as high as 40 million km2, accounting for 1/4 of the total area of the Earth's oceans.
At present, there are as many as 116 discovered and announced distribution areas of methane hydrate in the world. The thickness and scale of the ore layers are incomparable to conventional natural gas fields. Scientists estimate that the reserves of methane hydrate on the seabed are enough for human use for at least 1,000 years.
Therefore, Xiang Yang himself also attaches great importance to combustible ice as a new energy source.
