Actually, the pattern you are seeing is the ocean floor (an iso-surface). I'm
not quite sure why the crest of each ridge gets highlighted quite so much,
although nor am I convinced that such lighting is unrealistic.

The caustics cast by the ocean surface are much subtler.

That aside, even the ocean floor probably needs a bit more turbulence than is
seen here. Thanks.
