I put together some ocean sound effects for Overgrowth, The object ocassionally plays an ocean wave sound every 1.5 - 5.0 seconds, but if you want to change that time, you can edit the oceanwaves.xml found in Data/Objects/Sounds and change the min and max time.
use them in your levels for a nice ocean sound effect!
(Image below is a little sneak peak of a map I'm making
