Parametric "Beaufort scale" ocean

Hi! I’ve been reading your works on and I could tell you that it is really beautiful! I’ve been playing things myself with ocean waves using gerstner wave from tessendorf and I’ve got some questions for the ocean detail.
How do you handle the foam details to occurs only on the crest section of the waves? Do you use opaque or translucency material? How do you handle the specular for the micro ripples?

The last screen shot was not using beafort scale anymore right? How do you transition between calm sea and stormy sea then?

Anyway, congrats on being a daddy !
