SO WHAT WAS IT?

The ocean made a sound that was so unbelievably powerful that it was picked up by underwater microphones over 3,000 miles apart and scientists don't even know what it was. So actually if we go all the way back to 1997 right now, NOAA researchers were using underwater microphones originally built to detect Soviet submarines whenever they picked up something they have never heard before. They're saying that it was an ultra low frequency sound that was so insanely loud that they just had to call it the "bloop" because they don't know where it came from. The sound was actually able to be detected from sensors by over 3,000 miles apart across the entire Pacific Ocean. Scientists have spent years trying to deploy microphones closer to Antarctica to track it down to try to see if it would happen again and they have a theory. The leading theory right now is that it could have been an ice quake which would have been a massive iceberg that's cracking away from a glacier and they have recorded similar sounds before but it kind of doesn't add up. NOAA themselves have never fully come out and said that it was confirmed because it's not. They said it's just consistent. And I don't know about you but with 95% of the ocean still being unexplored that's a little bit of a gap that's a little bit scary. Do we actually believe that it was just ice or what made that sound?
