Dolphins and Domes of Light?

Whilst googling for a sufficiently large boat with which to commit an act of piracy(Nat-Wu can explain)I ran across this link. Apparantly, in some parts of the ocean there can be found domes of light floating under the sea. If you swim in these domes, you are cut off from all outside sound and experience. I suspect that the author of this website has perhaps risen to the surface too fast a few too many times, and may shortly be seeing white domes of light wherever he goes. The fact that he's posting this on "etfriends.com" belies his credibility, but I suppose anything's possible in the great deep, as the movie "The Abyss" has shown us. Anyway it's short and amusing...check it out.
