First a brief introduction:

I'm Dave Story, and do occasional mild decompression diving in the
Monterey/Carmel Bay areas, sometimes with EANx during deco.  Most of
the decompression is deep decompression (too cold for long shallow
dives) so we do fairly short stops.  My biggests interests right now
are decompression modeling and education.  I'm working on some
visualization software in my spare time which ought to help folks
understand how decompression models work.

Now, on to a response:

In the 1991 AAUS International Symposium Proceedings is a really
interesting paper on the use of CCORs (Closed-Circuit Oxygen
Rebreathers) by the California Dept of Fish and Game to monitor and
capture Sea Otters.  The author spoke at the conference about how they
had progressed from bags and boats, to bags on poles and scuba, to
bags and poles on scooters, to their final configuration with CCORs
and scooters with front-mounted capture cages.

Turns out you can get a good CCOR for about $5K.  Draeger Lar V is a
bit more, about $8K.  I was interested until I realized that in
Monterey, with water temps 50-55F most of the year and surface-30fsw
conditions often very rough, it wouldn't do much good.

If you're interested, I can dig up the address to get the Proceedings.
I got my copy free for speaking, so I don't have the address handy. 

Cheers,
