What is saturation diving? When the diver breathes in inert gas, it dissolves into the body’s tissues and reaches equilibrium with the ambient pressure at the diver’s depth.

A diving bell can be locked out from a saturation chamber and lowered to the seafloor. A moon pool on the underside allows divers to exit and enter the diving bell.
