“I was told once that the deeper a person goes, the less buoyant your body is. Just wondering if anyone knows if this is true.”
It depends but for the most part no the buoyancy of your body doesn’t change. Liquid doesn’t compress and most of your body is water and other liquids.
Your lungs compress at this level.
What does change is the equipment you take with you. The little air bubbles in the wet suit compress and the air in the buoyancy vest does as well. When it compresses it provides less buoyancy.
Miscalculate at extreme depths and you can find it impossible to ascend.
Aha. So this is only with scuba divers, not free divers...that the buoyancy thing becomes an issue?
