"The Bloop" is the name given to an ultra-low frequency, extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration during the summer of 1997. The sound was traced to a remote point in the South Pacific Ocean. According to reports, the sound came rapidly and lasted for around one minute. NOAA’s system ruled out any man-made or geological sounds. The audio profile of the Bloop resembles that of a living creature.
