Unless you're viewing the ocean from a distance, I wouldn't recommend
using a surface normal.  Also, normals don't animate very well up
close.  I'd recommend an Isosurface, or a height field, maybe even both
unless you're talking about very deep water and not shoals or reefs and
such.

Unfortunately, I've never been able to come up with a satisfactory
method for doing this, so you'll have to figure that out yourself unless
somebody else can tell you how to do it.

I did see an animation once, where someone had made the water ripple as
an object move in it, but I can't remember where I saw it.

I hope this helps somewhat.
