The identification of buoyancy variables is crucial for divers to control their buoyancy effectively during a dive. The three buoyancy variables typically include suit compression, which refers to how the wetsuit or drysuit reduces in volume as the diver goes deeper due to increased pressure; gas consumption, which relates to the volume of breathing gas that affects buoyancy as tanks empty; and depth change, which deals with the effect of pressure changes with varying depths on buoyancy.

Swim technique, while important for overall diving performance and efficiency, does not directly influence buoyancy in the same way that the other three do. It primarily affects how a diver moves through the water, but it does not alter the physical principles controlling buoyancy. Understanding the specific variables that do impact buoyancy is essential for divers to manage their ascent and descent safely and effectively.
