Myths and legends from all over the world have featured sea monsters. Creatures that lurk in the deep of unimaginable size, power and ferocity. From Lovecraft’s gigantic Cthulu to the terrifying Nordic Kraken, to the biblical gatekeeper of Hell, Leviathan.

Hell, sea monsters have and continue to exist on planet Earth. In the era of dinosaurs, terrifying fish and reptiles trawled the ocean depths, snapping up whatever got in their way. Fossil records of behemoths the 16 meter Megalodon shark and the enormous Plesiosaur are evidence of this. Even today, carcasses of giant squids are found washed up on beaches.

But what if in the great, blue unknown, there lay something else. A colossus — a real Leviathan, in the flesh and blood.


This is “The Bloop” sped up 16 times. This was a sound picked up by NOAA undersea microphones in 1997, traced to an extremely remote location in the South Pacific. It doesn’t sound like much.

Except the microphones that picked up this sound were over 5000km away. Easily louder than the blue whale, the loudest animal in the world.

Several explanations do exist for a such a loud, low sound. Submarine explosions, gas columns and calving ice shelves.

Yet the low tone of the sound suggests something else. NOAA researchers suspect Bloop is probably animal in origin and the military says it’s not from anything they made.

Bloop is not the first sound with an unexplained origin. Five other sounds; Julia, Train, Upsweep and Slow Down have few, if any explanations.

Could it be a horrific beast straight out of Lovecraftian fiction? Or could it be a classified military experiment “The Man” won’t tell us about?

The ocean is a very, very big place. One only has to look out at the horizon on a sunny day to be overwhelmed by its size. We know more about the Moon than we know about the seas around us. Our knowledge of the ocean is literally, just at the tip of the iceberg and humanity has only skimmed at its surface.

Each time a submersible goes into the dark depths, people encounter alien creatures, with strobe lights and transparent bodies. Whatever it is that lies below the surface and whatever it is that made that sound, remains a complete mystery.
