I think it's isosurface trouble causing that.  Ever see the talk about the black
pixel problem with these sort of things?  max_gradient I believe.  I think it
might be related to that in part coupled with the refraction, but I'm not sure.
I haven't changed anything and rendered again yet.  Basically it could be just
the odd lines perpendicular to the shoreline (pointing out to sea) and surface
unevenness to blame mostly.
