In other undersea weird news, in 1997, Naval underwater surveillance systems used by NOAA picked up a frequency that indicated a biological creature that was exponentially larger than any known whale or giant squid. It was picked up several times in 1997 off the coast of Chile, but then never heard from again. CNN reported the finding in 2002 (why did the Navy wait five years to make it public? Hmm.)
The Navy archived the sound under the name “Bloop.” In our upcoming book, The Kronos Interference, we speculate that something much more sinister was behind the frequencies.
