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 ;-)

And finally, here is the final version of the scene.

...and because I failed to identify a couple of fundamental errors in my
code, here is a final final :-)
