Why will a diver become less buoyant as he swims deeper?

[Walter]

Assume it is a fully geared SCUBA diver, the answer is still depending on conditions. Fully geared only includes a wet/dry suit if water temps require it. I dive 6 month of the year in Florida "fully geared" with no exposure suit - they are not needed and further are not desirable. There is no need for a properly weighted diver (who is diving warm water with no exposure suit) to add air to his BC.

yeah walter.... let's confuse everybody who wants a straight-forward answer



bottom line is, generally speaking, bouyancy will decrease with depth due to ambient pressure reducing the volume of air pockets present, requiring a diver to use more air on the BC to retain the same level of bouyancy

ya but the question was "why"

Didn't realize that til after I posted....The details as to why is what was being asked..

<currently writing on the chalkboard 100 times "I will not post before I read context of the question" >

lol i think they just take the first answer they get

just like that, you're a celebrity

No. bottom line is, buoyancy will decrease with depth in some situations. Your answer is correct as you describe it, but it's also misleading as many dives do not meet the criteria you've set up. If there's anyone who is confused by my answer, they really need to take their OW course over again.

ok H2, how can an earthworm be asexual, and when he/she has little earthworms,
will they prefer BP/W or Vest style BC (and why?)

 

[H2Andy]

clearly a stroke earthworm!!!!

my earthworm would be DIR and dive nakkid (ultimate minimalism)

well, since the question was asked in a non-diving site, i figured most of the readers would not have taken an OW class to begin with, and would just be confused with all the minutea

(which is not to say you are incorrect, mind you ... just what level do we want to get into here -- being an oldtimer college professor, i figured i'd pitch the ball low to the entry-level (i.e. non diving) reader)

A diver becomes less buoyant because as you go deeper you will run into a giant octopus who will pull you down. Geez, I thought evrybody knew that!

 

[Divmstr223]

It's a trick question really.... The answer is "They both weigh the same".

:mooner:

What's buoyancy?
