Quakers — this is the name given by scientists to unknown sources of deep-sea low-frequency noise. A strange phenomenon has been regularly recorded since 1970, it looks like the roar of a gigantic creature and gave rise to a lot of urban legends about the sea monster.
In the 1990s, American scientists placed hydrophones in the equatorial Pacific Ocean, and were finally able to record the mysterious sound.
A strange signal, similar to the whistle of a motor ship, was first recorded in 1991. The sound was repeated in 1997, 1999 and 2000s. It was similar to the whine of a sea animal, sounded seasonally in spring and autumn and lasted for several hours with a break of 20 seconds.
At the same time, its volume was so great that it could be emitted by a creature much more massive than a blue whale. The approximate coordinates of the source were determined 2500 km south-west of Chile.
Today science puts forward
It is worth noting that similar phenomena were recorded in the Soviet Union. The phenomenon was noted by the naval forces and prompted the Navy to believe that this was the American system of direction finding for ships.
In the 1980s, the study of the phenomenon was
In Soviet science
Most likely, they sailed to Soviet submarines, mistaking them for marine mammals. However, mysterious underwater noises still remain a mystery to scientists.
