6 unexplained sounds of the sea [video]


The ocean has fed the imagination of humans since time immemorial and continues to mystify scientists today as they attempt to explain the sounds being received by the underwater microphones of the National Oceanic and Atmospheric Administration (NOAA).

In recent decades, there have been six as-yet unexplained sounds that have issued from the deep with what might be completely reasonable explanations or clues to creatures and circumstances we have yet to imagine.

Take a listen to all six in the video below, and feel free to throw NOAA a bone if you have any answers.

1. The Bloop

…The Bloop mimics marine animal sounds in some ways, but its volume is too great to be made by any sea creatures known to science. If your imagination is running away from you, you’re not alone: Plenty of listeners have jokingly linked the Bloop to Cthulhu, a fictional part-octopus monster created by sci-fi writer H.P. Lovecraft in 1928…

2. The Julia

This weird noise, which sounds almost like someone cooing or whining, occurred on March 1, 1999. The eastern equatorial Pacific autonomous array (a network of hydrophones) picked up this strange sound.

Like the Bloop, Julia is most likely the sound of ice. In this case, NOAA researchers suspect the hydrophones picked up the sound of a large Antarctic iceberg running into the seafloor.
