[SONAR LOG - OCEANIC INFRASOUND]:

The Bloop is an ultra-low frequency, high amplitude underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in the summer of 1997. The sound's source was triangulated to a remote point in the South Pacific Ocean, and was heard by sensors over 3,000 miles apart. The waveform matches that of organic life, but its immense volume suggests an impossible scale. Oceanic agencies worldwide have never identified the source.
