Green Sea Turtles have been known to do this too, although I am not sure if it is for communication purposes. The turtle might just have gas. I have a few marine biologist neighbors, I'll have to ask them.

Btw, you said "had"... are those bubbles the cause you don't dive with him anymore? Some buddies... tsk tsk tsk... disgusting.
