Subject: Fog in mask on gas switch

   I have noticed the same effect on deep air dives.  On two recent dives
in Miami to about 200FT on air, I noticed thick fog forming inside my
mask immediately following a switch from air to surface supplied 100%
O2.  I have not noticed the effect before.  These dives were a bit 
unusal becuase we have been experincing a strong "upwelling," which has
brought extremely cold water over the deeper wrecks in Miami.  The 
water temperatures on the bottom were 59 degrees on one dive, and 66
on another, with 82-84 degree water on decompression stops.  I have
not noticed this "fogging" on dives where the water temperatures on
decompression were similar to bottom teperatures, but I might not 
have noticed somehow.
