here's what youre looking at.
after flying over, I think I want to turn up the reflection just a bit more.
#declare Waves =
plane {
y, 0
pigment { color rgb c_water }
finish {
reflection 0.15
ambient .3
diffuse .1
}
normal {
waves 0.1
rotate y*45
frequency 500
scale 510
phase clock*-.5
}
}

That water looks to reflective, don't seems to vary according to the
incident angle and lack transparency. Did you use a variation of some
chrome texture ?
You should add an interior :
interior{ior 1.34 fade_color<0.2, 0.35, 0.9> fade_power 1001
fade_distance ValueDependOnScale} // 1.34 is for sea water
// fade_color for the sea water colour.
Then, use fresnel reflection AND conserve_energy in your finish.
Also, using pigment{rgbt 1} greatly help. Don't forget to add an under
plane to represent the sea floor.

This is part of your problem with water.
You should use rgbt 1 as your pigment.
Next, use 1-c_H2O_abs as your fade_color.
Use fade_power 1001.
Adjust fade_distance for the scale of your scene.
Don't forget to add an ior. Sea water's IOR is close to 1.34.
Don't forget to use fresnel reflection and conserve_energy.

thank you for the input, I was going for a quick sheet of waves the right color.
ior media was done with the Lego pool, and for 10 pixels, even in a short row of
shadows on the bottom of the pool under the boats, took 6 hours
looks like the color of ocean to me. this is 15 seconds on good render time,
sometimes 2 minutes not hours. media animations would need Google's computers.
I was not trying to see the fish, it needed to be fast and look like ocean, I
called success.

that's was before the adjustment, it was way too reflective and wrong color.
wrong waves factor and wrong scale.

totally surreal, actually had its pluses.

I'd still be working on frame 2 of the fly over.

I think it was Trevor Quayle?? spelling?
showed me sea water.
#declare ior_NaCl_H2O = 1.34; //35g/l
#declare seawater = material {
texture
{ pigment { rgbf 1 }
finish
{ reflection { 0 0.5 fresnel } conserve_energy
specular 1 roughness 0.01
}
#if (1) normal { n_Sea } #end
}
interior
{ #if (1) ior ior_NaCl_H2O #end
media
{ absorption c_H2O_abs
#if (1) scattering { 3, c_Sea } #end
method 3
intervals 1
samples 3, 3
aa_level 2
}
}
}
and pool water is there also, its in scenes thread

example did not include fade power.
added your comment for further testing,
thank you Alain!
fade_color<0.2, 0.35, 0.9> fade_power 1001

watching the waves roll in,
..... anywhere from 3-8 seconds between each wave crest. Wind waves range from
9-12 seconds. Ground swells range from 13-15 seconds, and strong ground swells
have a period anywhere from 16-25 or more seconds
normal {
//phase mod(frame,20) * .05 // 4 secs at 5 fps
phase mod(frame,100) * .01 // 4 secs at 25 fps
only waves I ever saw, water waves .. heh
