Joe,
I seem to
remember that the deepest emergency free ascent from a submersible was
accomplished by the British from a depth of 600 fsw.

on-board air.
This
brings to mind WHOI's simple operational rules for Alvin, quite obviously designed to keep it
out of trouble to start with. That failing, onboard mechanisms, such as
breakaway manipulators and crew sphere release, to make up for the
rest...except of course, hull breach.
I wonder
also, where the line is for a reasonable free ascent? To my thinking, once my
little PSUB would pass normal safe SCUBA depths 130' or so, well then...I might
as well be in the Abyss for all the difference it would make.
So
pre-determined operational guidelines, is a must.
Outstanding
post, will file this permanently...thanks Jay!
Joe
