Apologize in advance if this has been posted before I could not see it in the forums - :)

One of my mates brought this up the other day and I had never heard of this before so did some digging and found this.

During the Cold War, the United States Navy erected a vast array of underwater listening devices in order to detect and track Soviet nuclear submarines. These hydrophones were placed at roughly 3,000 mile intervals in the deep layer of water known as the deep sound channel, where cold temperatures and high pressures allow sound waves to propagate great distances. When the Cold War ended, rather than mothballing the Sound Surveillance System (SOSUS), the U.S. Navy lent the Cold War relic to science.

The array has since been used to track many fascinating undersea events, such as whale migrations, earthquakes, ocean currents, volcanic activity , and the shifting of Antarctic ice. But one sound captured by the sensitive SOSUS hydrophones has scientists puzzled. It fits the profile of a living creature, but for a creature to create this sound it would have to be significantly larger than a blue whale, which is believed to be the largest animal ever to have lived.

The unexplainable sound was detected several times during the summer of 1997, originating off the South American southwest coast at about 50° S 100° W. Each time that it was captured the ultra-low frequency sound rose rapidly in frequency over about one minute, and had sufficient amplitude to be heard on multiple sensors from over 3,000 miles away. Perplexed researchers, unable to identify any possible source for the sound, dubbed it “The Bloop.”

The sound shares many characteristics with those emanated from biological creatures, in fact it fits those parameters so closely that a large number of researchers are convinced that its origin is animal. But in order for an aquatic animal to emit a sound that can travel over 3,000 miles though Earth’s noisy oceans, scientists say that it would need an incredibly large noise-making apparatus, one much bigger than that of the blue whale.

Theories abound as to the source of the Bloop. If it is the vocalization of a living organism, it is one which makes its home in the dark, cold depths of the ocean. Some have suggested that giant squids could be responsible for the sound, but that is unlikely considering that no known species of cephalopod have the gas-filled sac necessary to reach such great volumes. Indeed science has not recorded any animals– living or extinct– with nearly enough size to house the organs needed to produce the level of output demonstrated by the Bloop… so unless this mystery creature uses some unknown mechanism to generate sound, it is presumed to be an incredibly massive organism.

Blue Whale skeleton at the Long Marine Laboratory, University of CaliforniaFurther study of the Bloop is hampered by the fact that it has not been heard since the summer of ’97. It is almost certain that unseen creatures still lurk in the deep and dark oceans, creatures which are strange and fascinating. Such an unknown animal may have uttered these sounds while lingering at an unusually shallow depth. Unless researchers encounter the sound again, there is little chance that we’ll have any explanation more concrete than scientific speculation. But given its unusual properties and strong indications of a large biological origin, it makes for a compelling mystery.

EDIT >> Found this :O

That's quite interesting. I can't help agreeing with one of the commenters on the article that you've C+P'd in that it's unlikely to be some kind of whale, as it'd have to surface for air and someone would have noticed it by now. Some other kind of creature could be possible I guess.

Agreed Moosh I believe if there is something there its not going to be captured on film within our lifetimes lol. As to what it is I have no idea and couldn't make an educated guess :S

There is a Science Fiction short story called 'The Foghorn', by Ray Bradbury, about some such gigantic submarine animal that is summoned from the abyssal deep by the sound of a foghorn mounted on a lighthouse.
Full text of the story here:
Those foghorns do indeed utter a spine-tingling sound, I think the instrument was discussed and described in these forums some time ago.

Cthulu farting?

Could it be some kind of geological event, like an undersea volcano?

Could this, from the 'Who F*rted?' thread, be a clue?
