Unraveling the Mystery of the Ocean's Roaring Enigma Decades Later
The mysterious 'Bloop' sound that puzzled scientists since 1997 has been identified as an icequake, a noise produced by an iceberg cracking and breaking away from an Antarctic glacier. Initially thought to be from a variety of sources, including marine animals or human activity, the sound was traced by NOAA researchers to ice movements in the southern ocean. With climate change accelerating ice loss in Antarctica, icequakes are becoming more frequent, contributing to the array of strange noises recorded underwater, many of which have now been explained.
