Bloop

Bloop was an ultra-low-frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in 1997. The sound was consistent with the noises generated by icequakes in large icebergs, or large icebergs scraping the ocean floor, but in 2002 was said to also be consistent with large marine animals. NOAA believes it has now analyzed it conclusively and the noise was ice-related. However the true source of the sound still remains unknown.
