  2. Doing It Right (scuba diving) - Wikipedia

    en.wikipedia.org/wiki/Doing_It_Right_(scuba_diving)

    Buoyancy control is considered both an essential skill and one of the most difficult for the novice to master. Lack of proper buoyancy control is likely to disturb or damage the surroundings, and is a source of additional and unnecessary physical effort to maintain precise depth, which also increases stress. [28]

  3. Neutral buoyancy - Wikipedia

    en.wikipedia.org/wiki/Neutral_buoyancy

    Neutral buoyancy occurs when an object's average density is equal to the density of the fluid in which it is immersed, resulting in the buoyant force balancing the force of gravity that would otherwise cause the object to sink (if the body's density is greater than the density of the fluid in which it is immersed) or rise (if it is less). An ...

    Buoyancy control is considered both an essential skill and one of the most difficult for the novice to master. Lack of proper buoyancy control increases the risk of disturbing or damaging the surroundings, and is a source of additional and unnecessary physical effort to maintain precise depth, which also increases stress.

  5. Wetsuit - Wikipedia

    en.wikipedia.org/wiki/Wetsuit

    The total buoyancy loss of a wetsuit is proportional to the initial uncompressed volume. An average person has a surface area of about 2 m 2 , [ 14 ] so the uncompressed volume of a full one piece 6 mm thick wetsuit will be in the order of 1.75 x 0.006 = 0.0105 m 3 , or roughly 10 liters.

    neutral buoyancy. See: Buoyancy. Having a fully immersed buoyancy exactly equal to weight, so that the forces are balanced and the person or object statically remains at a constant depth. Effectively average density is equal to that of the surrounding fluid medium. The state of neutral buoyancy is typically metastable for a compressible system ...

  7. Buoyancy compensator (diving) - Wikipedia

    en.wikipedia.org/wiki/Buoyancy_compensator_(diving)

    The buoyancy compensator is used by ambient pressure divers using underwater breathing apparatus to adjust buoyancy underwater or at the surface within the range of slightly negative to slightly positive, to allow neutral buoyancy to be maintained throughout the depth range of the planned dive, and to compensate for changes in weight due to breathing gas consumption during the dive.

  8. Snuba - Wikipedia

    The harness holds the regulator and the air line in place, allowing the diver to swim unencumbered beneath the surface. [1] Full scuba gear, which includes a buoyancy compensator, weights, and cylinder, can weigh in excess of 27 kilograms (60 lb), [10] but this is not strictly comparable, as it would usually include a wetsuit for thermal ...

    Buoyancy problems due to weight of tools—Inability to achieve neutral buoyancy for ascent and positive buoyancy on surface. Increased risk of drowning. difficulty in controlling ascent rate. Risk of losing tools if they must be abandoned. Carrying an excessive weight of tools. Tools may be lifted and lowered to the worksite using a rope. [68]
