Hi Morayers

Here is an isosurface sea made with Stephen's Isosurface plugin.
You'll have to set the correct path for "functions.inc" in scene settings
"includes" tab.
Usually it is in the include folder of POV installation folder.
I put an alternative fast material (no interior, no transparency) for the
sea to be rendered faster.
I used  -as many-  f_ridged_mf  function.
The function parameters you find in #declare A thru G are:
Scale_x and Scale_y... self explain
"Damp" is relative attenuation for small waves and ripples.
"Lacunarity" is like Lambda for turbulence: factor between "octaves"
"Octave" like octave in turbulence
"Offset" is relative smoothness of lower zones
"Gain" sharpens ridges
The cylinder is there to test interior properties.
I'm still not quite satisfied with absorption and scattering behaviour: I'd
like a color from fully transparent at the surface to black at great depth
via well saturated emerald green for average depht as we can see here in
Brittany while sailing by open sea but I can't achieve that :(.
Sky is a media sky but it renders not too slow and I like the blueish haze
it gives :)

Advices and comments are welcome

Cheers

Marc
