The bloop – An Unexplained Phenomenon [Actual Sound]
''The Bloop is the name given to an ultra-low frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) several times during 1997. 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. The source of the sound remains unknown...''
''Scientists determined that its wave pattern indicates it was made by an animal, and not a giant electromagnet sucking a plane out of the sky, as the creators of Lost were no doubt hoping.''
''While the audio profile of the bloop does resemble that of a living creature, the system identified it as unknown because it was far too loud for that to have been the case: it was several times louder than the loudest known biological sound.''
''There is no animal big enough or loud enough to make that kind of noise, not by a long shot. Not a blue whale, not a howler monkey, not a startled teenage girl.''
What could have possibly caused this sound?

This is a slowed down version of the NOAA's originally released 'speeded up version,' which was 16x normal speed. This recording has been slowed 16x to recreate the real time recording.
