The Bloop: A Mysterious And Huge Underwater Sound
When the Bloop was first reported by the National Oceanic and Atmospheric Administration, the media began to speculate that it was caused by a giant undersea creature. The noise seemed "organic" in nature, and this designation fed into the rumors that the noise signified something much bigger than a blue whale. Fittingly, the location where the Bloop is said to have originated is less than 2,000 km from where H.P. Lovecraft placed his fictional city of R'yleh, where the ancient entity Cthulhu resides.
