Bloop

Bloop , mysterious ultra - low frequency underwater sound which was detected by United States National Oceanic and Atmospheric Administration (NOAA) during the summer of 1997.This sound was nicknamed as Bloop by scientists.

It was strange and mysterious , as the loud sound with low frequency was picked at stations which were immersed and over 5000 km away from each other . NOAA used acoustic hydrophone array in the Pacific ocean originally developed by the US Navy to track Russian submarines . Bloop was heard on multiple sensors. The sound appeared to be somewhere around 50° S 100° W. Initially NOAA believed that sound matches the profile of a living animal,but no known animal could have produced this sound as the range of sound produced would have to be many times larger than the largest whale.

Some people linked Bloop with gaint sea monster , an unknown animal which created these ultra - low frequency underwater sound that elevated it to  level of a great unsolved mystery. The actual origination of the sound is unknown and remains a mystery to this day although it is suspected to be biological in origin.

However, NOAA now thinks the sound never came from any animal, it believes that noise was from the cracking of ice as it breaks apart in the Antarctic when ice quakes hit . So the idea of some sort of colossal animal making the noises that were loud enough to be heard all over the Pacific was fantasy and not science.

NOAA claims that Bloop signals were similar to ice cracking that created natural echoes.Every year there are thousands of ice quakes which happen when glaciers crack and fall into the ocean. These sounds were all very alike in character to the Bloop itself .Because of that, it makes it particularly unlikely the sound was made by any kind of animal. 

The deep oceans of the world are still for the most part uncharted by human beings. It has been declared that there is a lot out there that humans do not know about the deep oceans.

One scientist who works for NOAA  doesn't believe in the ice quake theory and still stands behind the unknown animal theory. When it was said and done, the Bloop sound has not actually been completely 100 percent solved, and all the chatter about icebergs remains inconclusive when all is said and done. It does remain the chosen scientific answer at this time but the real mystery continues.

Honestly, at this point,  it's really nice to know that oceans have seriously hardcore mysteries alive!!
