The Bloop - Worlds Strangest Sounds - What Lurks Beneath ?

In 1997 NOAA's hydrophone arrays designed to monitor undersea seismicity, ice noise and marine mammal populations detected a mysterious sound. An ultra low frequency extremely powerful undersea sound.

They called it Bloop.

The sounds source was triangulated to a remote point in the South Pacific Ocean west of
the southern tip of South America.

It had a range of over 3000 miles.
It's signature was similar to that of sounds made by marine beasts.
Only it was far louder and bigger than any sound made by any known animal ever.

Several times louder than the blue whale, the loudest animal ever recorded
the source  was a mystery. Could creatures larger than whales be lurking
in the oceans depths?

It was then speculated that the source of the sound could be an icequake.
The sounds animal signature however, caused then to go back to the creature
theory. Then they went back to the icequake theory.

Fact is, they just aren't sure.

Popular imagination was sparked and theories abounded.
Megalodons roaming the depths and mystical sea creatures, all were contemplated.

Over 99 % of our oceans remain unexplored. and what may lurk in their depths is sill a mystery.
strange tales of sea monsters have always existed and have persisted till modern times.

In 1978 the USS Stein a U.S. Navy Vessel, was attacked by an unknown sea creature.

The rubber coating on the sonar dome was damaged by multiple cuts.

Nearly all of the cuts contained remnants of sharp, curved claws found on the rims of suction
cups of some squid tentacles.

The claws however, were much larger than those of any squid discovered.
The incident took place in a remote Southern Pacific location.

The Bloop Returns.

In February of 2015 Russian scientists detected a sound eerily similar to the Bloop
originating from the same location.

When the recordings were overlapped for analysis they were
an exact match.
