So I clicked to fast on send.

Sea surface by Jaime Vives Piqueres; World Machine for Deception Island; 
RV Polarstern courtesy by Alfred Wegener Istitut; Me, cloned by Poser. ;-)

Interesting detail: 12 hours after this photograph, the wind was howling 
at 11 to 12 Beaufort...

Awesome polar explorer beard! Do you still sport it?

And in what temperature this picture was taken?

See you in Khyberspace!

Lol! I have sported a beard for most of my life, i.e during the last 54 
years or so.

Well, it was a mild, quite, afternoon in fact, about 10-15 C, I believe, 
and very little wind. The reason why I was so dressed was that we were 
going to land on Deception Island and, as the weather is notoriously 
unreliable in those parts, we were advised to dress "properly". And no 
joke either: a couple of hours later we were hurriedly "rescued" from 
the island because of worsening weather conditions and rapidly growing 
wave heights. During the following night that hurricane struck.
I shall never forget that night! I was on night shift monitoring the 
seismic acoustic survey equipment running while the ship was completing 
transverse seismic lines across the Bransfield Strait. The wind however 
was so fierce (11-12 Beaufort) that the Polarstern was constantly blown 
away from its preset course. So, I was regularly called up to the bridge 
to decide what to do and/or how to resume the course. Imagine taking the 
stairs from the bottom of the ship till the bridge (about the highest 
point) while the whole thing plunges and rises and rolls several meters 
in each direction! And then you come into a dark place (the bridge) 
where there is.... only one officer on duty! The ship runs totally 
automatically under "normal" conditions. Following that, you are asked 
to tell what to do and where to go as the ship is drifting/blown 
dangerously towards the coast of the Antarctic Peninsula and the seismic 
line is a kind of crazily weaving pattern across the strait. For a short 
while, you feel very powerful :-) Seasick? I have never been seasick.
In the end, the Polarstern had to take refuge at the lee side of an 
island and wait for the end of the hurricane, which happened suddenly in 
the morning. That day was my birthday.

Thanks for sharing it.

Just looked up the Polarstern ship's Wikipedia page - interesting stuff.

Very nice.  I thought the same. water off the tails, and the surface 
near the tails needs some perturbance. Like the whale should be pulling 
the water in with the tail. Maybe even just a ring or two to show the 
disturbance to the surface.

I thought the overall surface shape and foam were fine.  The foam 
distribution seems thin front and center, like maybe from a boat wake.

Thanks for the comments indeed. I am working (slowly) towards the "water 
curtains" from the tails. I am almost done. The disturbance around the 
whales/tails would be an interesting addition: I shall probably opt for 
some extra foam (rings) around them. More work to do then ;-)

I have been mostly busy with fine-tuning further the sea media and the 
overall illumination of the scene. In addition - of course - other 
things drew my attention (and time) like, for instance, the addition of 
spline data to an isosurface. That one still has my brain boiling 
furiously, thanks to Christoph Hormann and Mike Williams. :-)

Here is a new version of the scene. Some profound changes have been 
driven through, especially concerning the sea. I am working on a couple 
of minor improvements, notably the whales' tails which are too rigid 
compared with the real things.

I like both the scenes, but I prefer this one, it's more... happy ;-)
