Bloop



Have you ever heard of “the Bloop”? It is an ultra-low frequency and extremely powerful underwater sound. It was detected by the U.S. National Oceanic and Atmospheric Administration in a southern part of the Pacific Ocean in 1997. Now, the hydrophone array that picked up the sound was in a very remote part of the ocean. You may want to keep that in mind.

In the NOAA’s words, the Bloop "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 NOAA does not believe it was a sound that came from a man-made object, such as a submarine, bomb, or even something like an underwater volcano. Nope, the audio profile of the Bloop resembles those of other marine animals. 

The kicker?

Even if the audio profile resembles that of an animal, it is several times louder than the world’s loudest animal, the blue whale.

Is it possible that some creature, larger than any whale, is lurking in the depths of the ocean?
