OK, once more for the slow learners, and I will type slowly so as not to
lose you.

In ruff seas, you are going to either be drifting or on an anchor line of
some sort.  If drifting shoot a lift bag.  If on the anchor line, run a jon
line, then shoot a bag.  When the five foot wave comes, guess what?  You
move up and down in the water column!!! Your PO2 is constant!!! Magic!!!
Wow!!! Cool!!!

Once again, who is teaching this stuff?
