Explaining the Unexplainable | Bloop


In 1997, a creepy sound was picked up by separate underwater microphones from the depths of the South Pacific. Named Bloop, it was unprecedented in that the microphones were situated over 5000 km apart (that’s about 3100 miles). This suggests that the source was very large and incredibly loud.

Naturally, this caused quite a stir. A bunch of theories arose in an attempt to explain the sound, the least scientific of which came from fans of H.P Lovecraft, who suggested the sound was made by the almighty Cthulhu. They were even more excited when scientists pinpointed the source of the sound to be uncannily close to that of Cthulu’s lair. *insert ominous sounds here*

There was also some speculation of the sound coming from some other unknown leviathan from the abyss. Hmm…*insert even more ominous sounds here*

Scientists from the National Oceanic and Atmospheric Administration (NOAA) have come up with the more plausible theory that Bloop is actually the sound of ice cracking as it breaks apart when icequakes hit in Antarctica. Sounds recorded by scientists between 2005 – 2010 in the Southern Ocean confirm that Bloop is essentially indistinguishable in regularity, duration and timing. But not everyone is convinced. Said David Wolman –

Fox’s hunch is that the sound nicknamed Bloop is the most likely to come from some sort of animal, because its signature is a rapid variation in frequency similar to that of sounds known to be made by marine beasts. There’s one crucial difference, however: in 1997 Bloop was detected by sensors up to 4800 kilometres (2982.582 miles) apart. That means it must be far louder than any whale noise, or any other animal noise for that matter. Is it even remotely possible that some creature bigger than any whale is lurking in the ocean depths? Or, perhaps more likely, something that is much more efficient at making sound?

So, there you have it. You can hear Bloop for yourself here, in real-time. Skip to 00:44 to hear it and formulate your own valid/wild conclusions!

…scary, huh? Personally, I thought it sounded like some sort of colossal ocean robot -it actually reminded me very much of reapers from the Mass Effect series. I love how the sheer immensity and sense of unknown regarding what lurks in the depths makes people’s imaginations go wild.

And it leads very nicely to the topic of the next set of posts 🙂
