In the sixties, the U.S. arranged a series of powerful underwater microphones (hydrophones) at strategic points in the Atlantic and Pacific oceans, to several hundreds of meters deep. The spy network called SOSUS submarine hearing, Sound Surveillance System. His mission was to "hear" the passage of Soviet submarines by these oceans and to alert the U.S. Navy. Currently still remains the network of hydrophones but at the end of the Cold War, declassified the project and allowed its use to scientists, biologists, oceanographers, etc.
Throughout the nineties and even today, occasionally fail to capture these scientists and record sounds of unknown origin that can be located thousands of meters deep . It has been dubbed the most famous of them as "The Bloop " because it is more like onomatopoeia recorded sound. Some of these sounds are believed to be caused by underwater earthquakes and volcanoes and has not yet been reach abyssal depths, where the ocean floor a much larger mystery to scientists than outer space. But some of these sounds challenge the knowledge accumulated by scientists to date.
Location sound
Christopher Fox of the U.S. National Oceanic and Atmospheric Administration's Acoustic can you tell if a sound is produced by a living being by a series of marks "on the sound . Some of these unfamiliar sounds recorded by the system SOSUS seem to have a biological origin, but more mysterious is that, judging by the intensity of sound recorded by sensitive hydrophones located at large distances between them, which captured the sounds and allowed them to locate the source, it follows that, if sounds produced organically should be a giant sea creature, much bigger than a whale . Monitoring Project in Portland, said the sound waves are like fingerprints:
is exciting as it was then strong comeback the romantic idea of \u200b\u200bthe existence of sea monsters and the kraken in this world and almost lost his sense of wonder about the unknown. Some even venture to name the Cthulhu himself, as some of the recordings were located near the area where the horror story writer HP Lovecraft placed the mythical R'lyeh, the sunken city where sleep this being immortal who came to Earth from the stars long before the appearance of life on the planet, hoping to reimpose his reign of nightmare and madness.
less fun
Another hypothesis is that it also could be sounds produced by shock, friction, cracks and dips of large icebergs . These sounds can be caught the so-called deep sound channel, an area of \u200b\u200bdeep underwater where the pressure and water temperature cause the sound to be trapped and can travel thousands of miles without dissipating horizontally vertically. But what we know now, it could also be not previously recorded sounds produced by animals known to drastically alter their behavior may sound (read the post " A seals would like Pink Floyd).
You can hear some of these unfamiliar sounds of the deep online and judge yourself but I'm trying to memorize the following verse in case I needed in the future: ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn.
