Who are bubbling at the bottom of the ocean?

In 1997, in the depths of the Pacific Ocean hydrophones recorded the mysterious "gurgling". Loud, at ultra-low frequency sound which is heard underwater stations located at a distance of over 5000 km from each other.


The National Oceanic and Atmospheric Administration (NOAA) began exploring the nature of this mysterious sound. The most popular version was that mysterious "gurgling" belongs to an unknown giant marine animals. Such a theory of time has acquired a mass of legends and raised it to the level of the great mysteries.

 

 


However, in the NOAA sure that the sound does not belong to an animal, and nothing mystical in it. Most likely, the scientists assume it is due to fairly banal phenomenon — the split ice shelf in Antarctica. All of the proponents of this version believe it reveals the mystery of the origin of the sound. It also confirmed a seismologist Robert Dzyak Oregon. And the stories that the "mega-gurgling" antics of a giant sea monster — no more than a fantasy, and science is not even smell.

Dzyak explained that "the frequency and duration of the sound is quite consistent, and, in fact, identical to sound a cracking ice." They recorded it while in Antarctica. According to seismologists, scientists have begun to study the acoustic in the Bransfield Strait and Drake Passage in 2005. It lasted until 2010. Because of the acoustic analysis, it became clear that the sounds of the icebreaker are the dominant source of natural sounds in the Southern Ocean. Each year, tens of thousands of times what happens is what is called "ledotryaseniem" of crack and melting sea ice, they are separated from the glacier and head to the ocean. All this is accompanied by a distinctive sound "gurgling".

All this almost eliminates the chance that the planet has alarmed the sound may belong to an animal. And in actual fact, the researchers note, no one seriously to this release and is not treated, people just like the great mystery.

In addition, shed light Dzyak Robert, sound, audible on the video simply speeded up because it seems that it plays an animal, but if you listen to it in real mode, it looks more like a thunder. There is even an opinion that simply sound distorted noise equipment. According to seismologists, almost all of the sounds can be divided into several categories: geophysical (underwater volcanoes and earthquakes), the weather (storms, waves, wind), anthropogenic (ships, air guns), ice (sea ice, icebergs stranded), and the animals (cetaceans, fish). The rest, as a rule, only a variety of electronic interference signal.

However, adds Dzyak, he understands why people are so easy to believe in the theory that "gurgling" belongs to the Sea giant. The depths of the ocean are still studied by mankind by only five percent. In New Zealand, for example, recently washed up on shore whale, what has never been seen by people. So what we know is that we know very little about the deep ocean.

By the way, the place where he first heard the sound, is only 1,760 kilometers from the location of the sunken city of R'lyeh, where, according to Lovecraft, deep, deep in the ocean floor is enclosed in its underwater dungeon mythical monster Cthulhu.
