Basic Information

The Bloop was an underwater acoustic phenomenon spotted in the summer of 1997 in the southern Pacific Ocean, off the southwestern coast of South America, by equipment of the United States Navy. It was audible over a distance of 5,000 km, and while it matched the audio profile of living creatures, it would have been much larger than even a blue whale to make that sound.
