 Buoyancy
We say positive buoyancy creates floating, negative buoyancy creates sinking, and neutral buoyancy creates static positioning (neither floating nor sinking) in water. Wetsuits and adding air to our BCs create positive buoyancy. In our lungs, inhalation and exhalation of a typical air capacity of 2 - 4L equals 2 – 4kg of buoyancy we can control.
