Calculation of the required weight and buoyancy volume to compensate for gas use can be done if the mass of the stored gas is known. Compensation for wetsuit buoyancy loss is a bit more complex and depends on the type and thickness of neoprene and surface area of the suit, and is best determined by experiment. Dry suit buoyancy loss can, and ...
Divers wear diver weighting systems, weight belts or weights to counteract the buoyancy of other diving equipment, such as diving suits and aluminium diving cylinders, and buoyancy of the diver. The scuba diver must be weighted sufficiently to be slightly negatively buoyant at the end of the dive when most of the breathing gas has been used ...
In scuba diving, the ability to maintain neutral buoyancy through controlled breathing, accurate weighting, and management of the buoyancy compensator is an important skill. A scuba diver maintains neutral buoyancy by continuous correction, usually by controlled breathing, as neutral buoyancy is an unstable condition for a compressible object ...
Any change in depth from a position of neutral buoyancy and even small changes in volume, including the act of breathing, result in a force toward an even less neutral depth. Thus, maintenance of neutral buoyancy in scuba is a continuous and active procedure—the diving equivalent of balance, in a positive feedback environment. Fortunately ...

Diving physics, or the physics of underwater diving, is the basic aspects of physics which describe the effects of the underwater environment on the underwater diver and their equipment, and the effects of blending, compressing, and storing breathing gas mixtures, and supplying them for use at ambient pressure.
A buoyancy assisted lift is a common procedure for recreational divers to assist the recovery of the shotline or anchor, which would otherwise be pulled up manually. A small lift bag attached to the shot is partially filled by the last diver to leave the bottom, and after surfacing the crew pull up the line and the air in the bag expands as it ...
Scuba divers with good trim and neutral buoyancy. The trim of a diver is the orientation of the body in the water, determined by posture and the distribution of weight and volume along the body and equipment, as well as by any other forces acting on the diver. Both static trim and its stability affect the convenience and safety of the diver ...
