Here's one for the experts.

You are diving at sea level and you descend to a depth of 33 feet
sea water (33 fsw).  You fill your bouyancy control device with
enough air to become and remain neutrally bouyant.

The next day you arrive at 10,000 feet altitude to dive in a lake
that contains sea water.  You descend to a depth of  23 feet sea
water (23 fsw) and fill you bouyancy control device with enough
air to become and remain neutrally bouyant.

The question is, at 10,000 feet, does the bouyancy control device
contain less air, the same amount of air, or more air compared to
sea level?
