You're lungs don't change in volume. The air > pressure inside them is the same as the surrounding water. I don't > lose any bouancy at depth. The volume of gas when your lungs are full, does not change, but the weight of it does. Since water is, for practical purposes, not compressable, the increase in the weight of the gas in the lungs should cause a slight shift in buoyancy as it compresses. I suspect, however, that it would take a great deal of compression to make a noticable difference. |
