Use the same weight
Remove weight
If 2 liters of air are needed Your positive buoyancy will increase
in your buoyancy
compensator to maintain
neutral buoyancy at 10m in
the ocean, what will happen
to your buoyancy if you
ascend 3 m without
deflating:
Your positive buoyancy will
increase
There will be no change in
buoyancy
Your negative buoyancy will
increase
You will stay neutral no
matter if you ascend or
descend
Breathing gas consumption: Increases as depth increases
Varies inversely with depth
Increases as depth
increases
Decreases as depth
increases
Remains the same as depth
increases

If you have difficulty Ascend until the pressure is relieved and then attempt
equalizing pressure in your equalization
ears/sinuses while
descending, you should:
Ascend 2 meters and force
equalization
Stop and wait until the
discomfort subsides
Ascend until the pressure is
relieved and then attempt
equalization
Return to the surface and
re-initiate the descent
