In 1997 the US National Oceanic and Atmospheric Administration (NOAA) picked up a strange sound on their underwater hydrophones (sensors used to listen to underwater noise). According to NOAA, The Bloop, as the noise was nicknamed, rose rapidly in frequency and was loud enough to be heard on multiple sensors 5,000 km apart. That’s a little over 3100 miles.

Some say that the noise is consistent with ice quakes and ice calving, but there is a far more interesting theory circulating as well. There are some people who believe that The Bloop was made by a living creature, but that the creature would have to be far louder than the blue whale (which is currently the loudest known species in the ocean). At the very least it would have to be better at generating such loud noises, even if it wasn’t bigger than the blue whale. At this time scientists still don’t know with absolute certainty what the cause was, but I believe it was a kraken.

 

By the way, on NOAA’s website they do confirm that The Bloop was caused by an icequake, but I still like my kraken idea. Besides, now I can complain of a coverup and conspiracy!
