It’s hard to believe that one of the greatest modern mysteries on Earth is called “The Bloop,” but it’s apparently a very appropriate name for this once-observed, but never explained phenomenon.
In 1997, The National Oceanic and Atmospheric Administration recorded a strange sound in the South Pacific Ocean. This sound was unexplained and was incredibly loud as it was recorded by two microphones that were three thousand miles apart. The Bloop was described as ultra-low frequency and very powerful.
The strangest part about this sound is that scientists who studied the sound have concluded that it was made by an animal… but not any animal that they have identified. The fact that the Bloop has never been heard again only complicates this already strange puzzle.
Could it be an undiscovered organism located in the ocean? It would have to be big, but then again, we have explored so little of our oceans that it’s not outside the realm of possibility that something lives out there that we’ve never seen. Then again, perhaps it was something else… ice caving or an underwater volcano.
Until we hear another Bloop, there’s no way we can possibly begin to figure it out.
