Oh one more thing....

I am lacking something witty...

Well, ok, not so witty. I watched The Deep and what I liked the most was this underwater lake they filmed. It is dense, brine water surrounded by shells and resembles a sea shore. The brime even seems to lap up aginst the shells, just like waves.

Also, since there is little organic matter so far down, the water is crystal clear. And cold, like 33-35'F. There are also openings in the sea floor that turn the water into steam. However, since it is so far down and the all the enormous pressure, the water doesn't steam until 400'F, unlike normal boiling point which is 212'F.

FYI, the greater the pressure, the less time it takes to boil water - whether it be air or water pressure. This does not mean the water will be HOT, though. For example, water on Mars (signifigantly less pressure than Earth) would boil at 50'F.
