And one more thing: variable reflection.

The radiosity in MegaPOV doesn't need much tweaking for most 
scenes...just copy-pasting the values from one of the sample scenes 
often works.

Maybe just adding greenish-blueish areas on the sides would work...or 
make the sides partly transparent and fill it with a blue-green emitting 
media.

Hmm, they wouldn't look so out of place if there was a bunch of small 
ice chunks and slush around them...and don't forget that you could just 
use CSG to remove them. Or you could output an image for the height 
field and edit that.

Well, first, what do you mean by "manual changes"? I don't think there 
is anything you can do with height fields that can't be done with 
isosurfaces...
Anyway, it shouldn't be too hard to add your own ice floe. Just leave 
the current ones where they are, and put one as a separate object in 
front of the camera.
