Frequently cited as an “insane mystery science hasn’t solved”, the bloop looks to have a reasonable explanation. Was it a mystery monster squid as most commonly thought? Sadly, no.
First some background in case you haven’t heard about the bloop: Skeptoid
It came from the depths of the South Pacific. Throughout the summer of 1997, a sound never before recorded burst from the abyss. News agencies scrambled; was this some new leviathan, an unknown monster from the deep? Nobody knew, and though this recording has taken its place among the permanent fixtures of the museums of the strange, the Bloop has never been identified.
The broad spectrum sounds recorded in the summer of 1997 are consistent with icequakes generated by large icebergs as they crack and fracture. NOAA hydrophones deployed in the Scotia Sea detected numerous icequakes with spectrograms very similar to “Bloop”.
They have even identified the probable location.
