Diving Buoyancy

Buoyancy while scuba diving, snorkeling, or swimming is a safety skill. It also has multiple medical and diving implications. A diver’s air consumption and fatigue are strongly correlated with their buoyancy control. Ascent and descent in a water column (whether salt or fresh) when controlled, protects the diver from barotrauma of both sinus and middle ears, pulmonary hyperinflation, air embolism, and reduces the risk of decompression sickness. Buoyancy control also affects and protects both the diver and the marine environment.
