A very audible SPLASH! is one of the curious sounds that I hear coming out of the stillness of the night, from Minas Basin, off Horton Bluff. This is one of the frequent, interesting sounds I hear while observing the sky, at the telescope eyepiece, usually late at night.  It would be heard several times (perhaps a dozen or so) during a two hour observing session.  To be heard that well from off shore, it had to be from something fairly large.  Even though my eyes would be well dark adapted, the <splasher> remained a mystery.

Last year during the Tidal Power Conference held at Acadia, I learned from one of the researchers that the source of the sound I was hearing in the night was most likely coming from an Atlantic Sturgeon leaping well out of the water and falling back. So, now, when I hear this sound in the night, that is what I picture.
