In the category of "weird phenomena"...
Ladies and gentlemen, I present The Bloop.
The Bloop is the name given to an ultra-low frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) several times during 1997. The source of the sound remains unknown.
The Wikipedia page (linked above) includes an audio file of the phenomenon, plus a link to several other similar unexplained underwater audio incidents. Isn't it nice to know that there's still some mystery in this big ol' world of ours?
