don't call me singer

Chapter 694 I seem to have discovered something incredible!

Two thousand kilometers away, on the other side of the ocean, the United States, the waters outside San Francisco, California, near Angel Island and Alcatraz Island, is a famous whale watching resort.

And here, there is also a Caltech marine research ship Georgia floating quietly on the sea.

Caltech is one of the best private universities in the United States, and was even once considered the best university in the world.

The university has a very small number of fewer than 1000 undergraduates, 1200 postgraduates, 300 professors and 600 research scholars.

From the point of view of the number of people, it may not be as good as a college of Dongyuan University.

However, in such a small school, 38 alumni and professors have won 39 Nobel Prizes, and if other researchers are included, the number is as high as 74.

Not to mention other international awards such as Fields Medal and Turing Award.

It can be said that this small school with a combined population of less than 3000 people has gathered the world's top geniuses and top researchers, and everyone is a real powerhouse.

Caltech's physics, planetary science, and earth science are among the top in the world.

All the protagonists in the popular American drama "The Big Bang Theory" work in this school.

At this moment, Caltech professor of geosciences, ocean sciences, and marine biology Jeffrey Conona is listening to some of the recordings he just collected.

Jeffrey Conona is a well-known oceanographer in the world. He has profound attainments in marine geology and marine biology. Similarly, he is also very accomplished in hydroacoustics, because Hydroacoustics is the most powerful weapon for studying the ocean.

And he has always maintained a very strong interest in whales, because his father is an oceanographer who specializes in whales. Now the old man lives in a sanatorium in San Francisco because of AD. He often records many whales. singing, take it home for the old man to listen to.

Although the doctor said that the old man's brain has degenerated very badly, every time he hears the whale's singing, he still smiles and even restores some memories.

Perhaps because of the old man's influence, Jeffrey's graduate thesis is related to whales, and he basically conducts some follow-up research on his previous research and writes some papers every year.

But at this moment, his expression was particularly strange.

Wait, what's going on here?
Is this a whale song?

This is not right!

"Wang! When did you record this?" Jeffrey called one of his students.

The student called Wang looked at his record and said, "This was recorded at 22:47 last night, and it lasted about 16 minutes..."

"Have you heard?" Jeffrey asked.

"Uh, no, what's the matter?" Wang asked blankly.

Wang is a bright young Asian, a third-generation immigrant, and Jeffrey's favorite student.

But at this moment, Jeffrey had to wonder if Wang was trying to play tricks on himself.

But looking at Wang's bewildered expression, Jeffrey felt that Wang shouldn't take the risk of offending himself and failing the exam to make this joke on himself.

"Drop the drag sonar," Jeffrey ordered, and put the headset back on.

The Georgia dragged its long tug of sonar, which kept sinking and sinking.

Jeffrey also kept wearing earphones, listening to the noisy sound, until the sonar suddenly seemed to have pierced through a layer of membrane, and it quieted down instantly. In the next second, the surrounding sounds suddenly changed.

"Stop!" Jeffrey ordered.

The towing sonar stopped sinking, and it was quietly suspended at a distance of 200-300 meters below the seawater.

It's into the deep ocean soundtrack.

The deep sea sound channel is a very special acoustic phenomenon in the deep sea.

In seawater, the propagation speed of sound changes with pressure and temperature.

Above a certain depth, due to temperature and pressure, the speed of sound propagation above is fast, while the speed of sound below is slow.

After a certain critical point, the speed of sound propagation at the bottom will be fast, and the speed of sound at the top will be slow.

Sound always bends from the side with the fastest speed to the side with the slowest speed.

So, near this "tipping point," the sound bends back and forth without being lost to the air or absorbed by the sea floor.

The speed of sound attenuation becomes extremely slow.

This depth is called "deep sea channel".

This feeling is like an optical fiber of sound that exists in the sea. By continuously bouncing back and forth and refracting the sound, the sound can be transmitted to infinity.

At other depths, even the sound of cetaceans may only travel hundreds of kilometers before being completely attenuated.

But in the "deep sea sound channel", the sound can be transmitted tens of thousands of kilometers away, and even circle the earth.

The deep-sea sound channel is the "telephone line", "wireless broadcast", "chat room", and "world channel" of countless marine creatures.

Whenever you put the hydrophone into the deep sea channel, it is like entering a world of marine life.

Of course, most of the meaningful sounds are made by marine mammals.

There are humpback whales singing, killer whales cursing, dolphins flirting with girls, and sperm whales snorting and diving to listen to the fun.

And at this moment, the deep sea sound channels all over the world are dominated by a whale.

It adds a completely different melody to the traditional whale song.

This melody, the other humpback whales feel very novel, and a little bit overwhelmed.

This humpback whale is humming this melody over and over again very stubbornly.

Cheerful, magical, and a little brainwashed.

This is definitely not the song of whales, this is the music of humans.

It has distinctly human melodic characteristics, with mode, rhythm and pitch.

It's hard to imagine that this is the sound made by a whale.

Why does a whale sing human songs?

Jeffrey sat in front of the hydrophone all afternoon without moving a muscle.

During this afternoon, he heard more and more humpback whales, adding this melody to his whale song.

Whale songs are changing all the time, like a cetacean pop scene, always innovating.

But he had never seen a whale song change so quickly.

In one day, this melody became the most popular song of the deep-sea Maiba humpback whales!

What the hell is going on here?
Jeffrey felt that he seemed to have discovered something extraordinary!
In the cabin, Wang felt that his teacher had just melted away.

He came in to look once and found that the teacher was still sitting there.

Came in again, still sitting there.

Just when Wang was about to reach out to check if the teacher was still breathing, Jeffrey jumped up suddenly: "Wang, hurry up, I want to write a paper!"

"I feel like I've discovered something incredible!"

If this discovery is late, I'm afraid it will be snatched away by others!

And why do whales sing human music?

Is this an example of further human impact on the ocean?

And why do humans affect cetaceans?

Jeffrey already has countless conjectures and theories, and he can't wait to write this paper first!
He could imagine that this paper could cause a sensation!
