The Bloop

The Bloop is the name given to an ultra-low frequency underwater sound detected by the U.S. National Oceanic and Atmospheric Administration several times during the summer of 1997. The source of the sound remains unknown.

The sound, traced to somewhere around 50° S 100° W (South American southwest coast), was detected repeatedly by the Equatorial Pacific Ocean autonomous hydrophone array, which uses U.S. Navy equipment originally designed to detect Soviet submarines. According to the NOAA description, it "rises rapidly in frequency over about one minute and was of sufficient amplitude to be heard on multiple sensors, at a range of over 5,000 km." According to scientists who have studied the phenomenon it matches the audio profile of a living creature but there is no known animal that could have produced the sound. If the sound did come from an animal, it would reportedly have to be several times the size of the largest known animal on Earth, the Blue Whale

Exciting answer? The collective despair of dolphins and whales was orchestrated into a series of plaintive cries for respect. If we could translate the 'bloop' it would probably be saying, "For the love of God, pleeeease turn the noise down, stop killing our environment and ease up on the dumping your crap in our home!! Give us a fricking break!"

Standard answer: It was probably an outcome of unusual tectonic activity. The sound has been described...

"The sound waves are almost like voice prints. You're able to look at the characteristics of the sound and say: 'There's a blue whale, there's a fin whale, there's a boat, there's a humpback whale and here comes and earchquake," he says. But some sounds remain a mystery he says. Like Bloop -- monster of the deep?

Old CNN news article

Key words are 'almost like voice prints.' Not actual voice prints. It's accepted that no known sea critter could make a sound of that magnitude. Wasn't a whale and couldn't be a colossal squid. That pretty much leaves an unknown geological cause...and leaves us no closer to actually identifying it. As far as we know, it hasn't been heard since that summer.
