My Deep-sea Fishery

"Show me." Xiang Yang took the display screen from Xu Fang, and clicked play.

All I saw on the screen was a large expanse of blue water.

Suddenly, without any warning, a huge iceberg appeared in the video. This iceberg seemed to be born out of thin air, without any warning. After its birth, it did not cause any storms.

"Yes, it is indeed a mirage."

Xiang Yang handed the display screen to Xu Fang, "It should be because of the snow we fell earlier, which caused the refraction of light to deviate, so on this sea area, a huge iceberg is projected at an unknown distance. .”

At this time, more and more people gathered on the deck.

Many crew members, their hearts beating faster, watched themselves getting closer and closer to the iceberg bit by bit.

Although Xiang Yang and Xu Fang have made it very clear that it is not a real iceberg, but just a mirage, the visual impact is still extremely terrifying.

Xiang Yang himself is not afraid anymore, he is one of the few people in the entire fleet who knows the principle of the formation of mirages.

A mirage is an illusion formed by the refraction of distant objects. It is caused by a temperature gradient formed by the sun heating the ground.

Due to the different densities of the air, light will be refracted at the boundary of the temperature gradient.

The human brain thinks that light always travels in a straight line, but when it passes through the cooler, denser atmosphere below, it refracts downward, so distant objects appear taller to the brain than they really are.

Mirages often occur at sea, because the air humidity within a certain range of the sea is relatively high, and the thickness is also relatively large, so that a large area of ​​water vapor forms a huge lens system by accident under the movement.

When the temperature near the surface changes drastically, it will cause a huge difference in the density of the atmosphere, and the distant scenery will experience abnormal refraction and total reflection when the light propagates, resulting in a mirage.

In addition, the occurrence of mirage is also related to the refractive index of air layers at different heights, and the water vapor content is an important meteorological element that directly affects the refractive index.

At the same time, there is also a certain relationship between mirage and sudden changes in temperature and relative humidity.

The air near the sea surface has a higher refractive index due to the lower temperature of the sea water and the humidity of the water vapor, while the air above has a higher temperature due to the influence of sunlight.

The refractive index of the air layer above the sea gradually decreases from bottom to top with height. Due to the discontinuity of changes in meteorological elements, the change of the refractive index of light in the air also shows discontinuity, and the light passes through the air layer with a large refractive index. When it is at the top, it is easy to form total reflection in sunny, windless or light windy weather conditions, resulting in the spectacle of mirage.

At this time, Xiang Yang found that the decks of other fishing boats around were also full of people.

"It seems that everyone has also discovered this mirage." Xiang Yang said with a smile to the people around him.

"Brother Yang, you are still in the mood to laugh. If this is not a mirage but a real iceberg, then we will be doomed." Fang Youqun said.

Xiang Yang smiled and said nothing, whether it is true or not, the truth will naturally become clear when the fishing boat drives past.

As a result, just when Xiang Yang thought he was going to have zero contact with the mirage, the icebreaker that was driving at the front stopped.

Immediately afterwards, the second and third ships, all the fishing boats in the entire fleet stopped, and Xiang Yang's fishing boat had to stop on the sea.

"Hey, what is Boss Gao doing? Why did he stop?" Chen Qingsheng wondered.

Xiang Yang took out the walkie-talkie, "Let me ask."

"Mr. Gao, Mr. Gao." Xiang Yang shouted.

There was a lot of blind voices on the walkie-talkie. After a while, Gao Chuang's voice came from inside, "Is it Xiang Yang?"

"It's me, Mr. Gao, why did the fleet stop?" Xiang Yang asked.

"There is a mirage ahead, we will move on after the mirage passes," Gao Chuang said.

Xiang Yang shrugged his shoulders, looked at Chen Qingsheng and said, "Maybe Boss Gao thinks it's not easy to navigate in a mirage and his sight is obstructed."

Chen Qingsheng smiled and nodded, "It's good to stop, if the visibility in the iceberg is too low, maybe some of us will get lost."

Xiang Yang rubbed his stomach, "It's just right, after walking for a while, I'm hungry again, do you have anything to eat? I'll take two more bites."

"It's gone. The seafood at noon tastes so good. I've eaten all of it. There's nothing left. How about I go to the kitchen and cook some for you?" Chen Qingsheng said.

Xiang Yang shook his head quickly, "Forget it, I'll cook it myself, how dare I bother you, Master Chen."

When Chen Qingsheng heard that Xiang Yang wanted to do it himself, he hurriedly said: "Captain, let me do it. After all, the seafood on board is not cheap, so forget about your cooking skills."

Xiang Yang was not embarrassed either, he smiled, "Okay, it happens that I haven't eaten your dish for a long time, get some Antarctic sturgeon soup, let's go to the cabin and have a drink or two."

Hearing this, Fang Youqun immediately moved his head over, "Brother Yang, I want to eat too."

Xiang Yang asked with a smile: "Why, you didn't have enough at noon?"

Fang Youqun quickly nodded his head like a chicken pecking rice.

Immediately, a crew member dismantled Fang Youqun's platform and said, "Captain, don't listen to this nonsense surnamed Fang, he is the one who eats the most at noon, and he eats all of mine. I am really not full." that."

When Fang Youqun heard this, he immediately became anxious, "If you don't eat it yourself, why don't you allow me to eat it?"

Xiang Yang immediately laughed when he heard the words, "You all still want to eat again?"

The crew immediately said in unison: "I want to."

Xiang Yang looked at Chen Qingsheng with a smile, "Let's cook a few more Antarctic sturgeon, and get some green vegetables, radishes, and lotus root. Let's try the whole sturgeon hot pot soup."

Chen Qingsheng nodded and said with a smile: "Eating seafood is good for everything, but it digests too quickly. After a while, I'm hungry again. Okay, I don't know when this mirage will be able to digest food. Just make a Try the hot pot."

Seafood is mostly high-protein products. It is easy to feel full when eating, but after eating, you will be hungry again soon, so this is a very normal phenomenon.

Soon, several cauldrons for cooking Antarctic sturgeon were set up on board, and a dozen or so crew members gathered around a cauldron and continuously put various vegetables, fish balls, and fish meal into the pan.

Xiang Yang was stunned by this scene, "I just thought about having a bowl of fish soup after dinner, and you all only ate a pre-dinner dessert just now, this is the main meal."

Fang Youqun had a fish ball stuffed in his mouth, and said vaguely: "It's easy to drink fish soup, brother Yang, you drink the soup and give me the fish you don't want."
