Ted, does this mean you will turn into a huge fat bearded slob with a
pizza-stained Doria shirt and be participating in a Star Wars Bar Scene on
the Seeker? I wish the "Doria" would hurry up and disintegrate so the
strokes could all just lie about it instead of dying about it.
Here is what I would do for deco. I am not doing anything different because
of the cold - you took care of that by keeping the bottom time reasonable. I
am assuming that anyone who dives in the 40's uses C-4 , a proper WKPP type
hood and gloves , and argon.
< 23 bottom time
count all time as if at 240
your gas or anything close to that
deck to 150 - 2 min
140-80 5 min
70 - 3
60 - 3
50 - 3
40 - 5
30 - 8
20 - 15
5 minutes going to the surface from 20
Same for the next dive
This schedule will work up to about 25 minutes at the bottom.
On the last two days of diving, switch to the 50% at 60' instead of 70' and
do your oxygen at 18 feet or above, maybe splitting it into 18,15,12,9 or
something like that.
Your risk in this is exposure and depletion of brain chemistry. Don't party
with the mutants and take some vitamin E each day. If you go on the Seeker,
take some pictures so we can all have a good laugh.

George,
Since you are offering deco profiles, let's assume your going
to the Andrea Doria. The top of the wreck where the mooring will be
is 175' and the sand is 240'. Most of your dive will be between 220'
and 240'. You want to be on the mooring line at 175' with a run time
of 25 minutes. Assume a bottom mix of 16/50 or chose your own,
2 deco mixes, 40 degree bottom temperature, and 55 degrees from
50' to the surface. What would your profile look like?
You plan to repet 5 hours later with a 20 minute bottom time. How
much does the profile change?
Can you do this 2 days in a row (4 dives)?
