Keith,
Thanks for the comments, if you were right I'd be the first to agree
with you. Since the topic is a flooding drysuit we are concerned with two
variables; what is intruding and what is leaking out. In this case water is
intruding and since it is the same density as the medium you are in (duh),
there is no net change in bouyancy as long as the gas doesn't escape. A
typical flooding scenario would be a torn wrist seal (then there is the guy
that zipped just the outer zipper of his TLS-350...) which could easily
flood the suit without losing the gas.You could slip a garden hose under a
wrist seal and fill the suit up with no change in bouyancy as long as no gas
leaked out from the suit. It would be rather difficult to swim around
looking like the Sumo-Man but the water intruding would displace an equal
amout of ambient water, ergo, no change. Bouyancy will only change if the
gas volume changes.
