Researchers from the University of Massachusetts who study life in the deep ocean, it was possible to tape the strange sounds made by unknown creatures. And now scientists deciphering heard them underwater grunts, grunting, croaking, mooing and quacking.
About half a century ago, biologists who study marine animals found fish with muscles, pointing to the fact that it produces certain sounds, as reported in the edition of New Scientist. First suspicious noises in the ocean have been recorded a few years ago, after some research groups have also witnessed the exchange of audio signals underwater creatures.
However, in most cases, researchers have been unable to determine who is actually they heard. Oceanographer, Rodney Rountree (Rodney Rountree) interested in "talking" underwater inhabitants decided to join the small number of interpreters.
For example, during one of the scientific expeditions, he and his research team was sent to the waters of the North Atlantic at a depth of 682 meters a special device consisting of a microphone connected to a MP3-player, tightly wrapped in a waterproof polyethylene. All this biologists hid in crab traps. As it turned out, the waters of the North Atlantic hide a lot of exciting sounds. Altogether, there were 12 taps, cawing and many other screams. The frequency of sound was less than 1.2 kHz, indicating that underwater "chatter" belonged to marine life such as fish or whales.
The point of all heard so far is not clear to scientists. Rodney doubts the special purpose of these sounds, and believes that they are the inhabitants of the sea to search for each other in the mating season, as the light in deep enough, and the sound can be spread over long distances, passing information. For this reason, scientists are seriously concerned that the noise pollution of the oceans, which is created primarily by the courts, can drown out the mysterious deep sea creatures.
