What are the mystical sounds underwater in the ocean and where they come from

Water in general is a very interesting element. Due to its properties, it conveys sounds very well. To understand this process, it is enough to recall that sound is simply a vibration of the environment, which appears due to the vibration of something and is transmitted to our ears, causing the eardrum to vibrate. The ocean is generally an extremely mystical environment, which has hardly been studied, and from that the sounds that can be found in its depths seem even more mysterious. It may be tectonic movements, sounds of whales, human activity, or even the awakening of the Kraken. Whatever it is, this must be dealt with. Will we try?

You can meet anything under water. Even the sounds.

How to record sounds underwater

To get started, let's look at how sounds are detected underwater.

Many sounds can be heard even unarmedby ear. An example is the sound of a motor boat or a knock on the metal support of the pier when you swim near the shore and lower your head into the water. Even the fish that gnaw corals emit a very distinctive “chrome-chrome” when you are in relative proximity to them.

There are more complex systems in order tocatch the quietest and farthest sounds. For example, submarine equipment that can capture the quietest and farthest sounds to detect a potential adversary.

People can master echolocation, like dolphins. And it is surprisingly simple.

But there are peace ships that are equippedspecial highly sensitive sensors. They are needed in order to explore what is happening in the ocean, and record these sounds. Such a study helps to determine the habits of marine life and other things that may be important for exploring the world's oceans. Sometimes such sensors pick up a sound that is extremely difficult to explain. At least, scientists can not do this yet, and we can only guess and fantasize.

The ocean has not been studied enough to say that we know the nature of everything that happens in it.

Mysterious sounds in the ocean

First of all, it’s worth deciding what sounds, ohwhom we will speak of, do not belong to the category of mysticism. They really exist and are fixed with special equipment. You can even listen to them.

Bloop - Low Frequency Gurgling

For the first time this sound was recorded in the Pacific in 1997 at a point with coordinates of about 50 ° S. w. 100 ° C e. Ironically, this happened in the place where, according to Howard Lovecraft’s book, the flooded city of R’lieh is located, in which Cthulhu is sleeping and waiting in the wings. Many immediately thought that Cthulhu was waking up, and it was worth starting to be afraid.

And you will not meet such a horror under water.

It took scientists about ten years toto understand what they are dealing with and what Cthulhu really doesn’t even think of waking up. The reason turned out to be very banal and prosaic. This sound was made by icebergs, which cracked and vibrated, transmitting this sound thicker than water.

However, fans of conspiracy theological and mystical theories still do not believe in this and prove to each other that there is something very terrible there, which they simply don’t tell us about. In short, as usual.

Bio-duck - half a century of mystery

If the previous sound seemed mysterious to you, then pay attention to another one that military submariners have found back in 1960. Since then, for more than 50 years, the nature of this sound has remained a mystery.

The acidity of water in the oceans is gradually increasing. How does this affect animals?

In favor of the fact that an animal can have soundorigin, said that it was recorded every day, but strictly at a certain time of the year. Sounds had a duration of 1.5-3 seconds and a frequency of 50-300 Hz.

What if something like that can make sounds underwater?

Only in 2014, scientists proved that suchstrange sounds are made by Antarctic whales. Such a sound is made by whales just before they go to the depths. In many ways, therefore, it was impossible to determine the sound source for such a long time.

Upsweep - weird sound

Of the sounds we're talking about today, this onewill be the first to remain unidentified. Indeed, so far almost nothing is known about him. There are speculations that this could be, but to say that it was solved, it is impossible.

This sound was found in the equatorial partPacific and gave it the name Upsweep. Like Bio-duck, it is seasonal, although it is very loud to be of natural origin. It is so loud that it can be heard almost across the ocean.

Volcanoes can also make sounds underwater.

So far, scientists have not given an explanation for this.low-frequency fluctuation, but one of the reasons for its occurrence are considered geological processes. Its source is in an area with high volcanic activity. As a result, it can indeed be considered a consequence of geological processes, but it is too early to say so. There is no evidence of this, as well as the opposite.

Julia - whining sound

Following the sound was discovered on March 1, 1990. Something remotely it resembles a coo or whining, but very distantly. More, of course, it just looks like another low-frequency sound that comes from somewhere from the bowels of the ocean.

Not only sound, but smell: Martian oceans could smell hydrogen sulfide.

The sound was called Julia, and he recordedwas an autonomous network of hydrophones east of the equatorial Pacific. That is, about the same as Upsweep. Its nature, too, has not yet been solved, but in this case, scientists are more likely to believe that this is not tectonic activity, but the destruction of icebergs. It is not very clear how they can make such a stable and long-lasting sound, but they know better.

Slow Down - Slow Sound

Of course, there are a lot of sounds in the ocean, butThere’s no point in telling about everyone, and it’s just not interesting for you to read about it. In the end, I chose the most intriguing and talked about them in this article. In conclusion, I’ll talk about one more, which was called Slow Down.

This sound for the first time was recorded May 19, 1997. He got his name due to the fact that histhe frequency gradually decreases over about 7 minutes. The sound was simultaneously recorded by sensors that are located at a distance of about 5,000 kilometers from each other, indicating its high volume.

Since it was recorded in the areaAntarctic Peninsula, it has been suggested that with such a sound a moving iceberg scrapped the seabed. The version looks very convincing, but boring. Icebergs again ...

Where do the sounds in the ocean come from?

As you can see from the above examples, there are three main sources of sound formation. This is geological activity, icebergs and animals - usually whales.

There are such sounds underwater, but not in the ocean, of course.

Many sounds have not yet been guessed and this gives rise toto form a mystical halo around them, but you should not particularly zeal in this direction. In the ocean there is a lot of everything that can make sounds, and due to the fact that sound spreads better in water than in air, it can be heard so far and often with distortions.

When those sounds that are still unexplored are discovered, we will certainly tell you about it in our news channel.

Sometimes the sounds of the ocean are frightening, but some of them, on the contrary, can tune into relaxation and be a very good background for relaxation.
