Separate diving procedures are developed for each mode of diving, such as air and mixed gas diving, inshore and offshore diving, or recreational and professional diving. Decompression tables , programs and algorithms that prescribe depth and time limitations are also a subset of procedures, and highlight the unique nature of the hyperbaric work ...
In deeper diving, the scrubber needs to be bigger than is needed for a shallow-water or industrial oxygen rebreather, to provide longer dwell time, because of this effect. At low temperatures the scrubber reaction will be slower, and may not remove enough carbon dioxide if the dwell time is too short.
Human physiology of underwater diving is the physiological influences of the underwater environment on the human diver, and adaptations to operating underwater, both during breath-hold dives and while breathing at ambient pressure from a suitable breathing gas supply.
Deep sea diving is underwater diving, usually with surface-supplied equipment, and often refers to the use of standard diving dress with the traditional copper helmet. Hard hat diving is any form of diving with a helmet , including the standard copper helmet, and other forms of free-flow and lightweight demand helmets .
The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes , sea turtles , the marine iguana , saltwater crocodiles , penguins , pinnipeds , cetaceans , sea otters , manatees and dugongs .
It is designed for decompression diving executed deeper than standard recreational diving depth limits using trimix as a "bottom mix" breathing gas. There have been three iterations of UTD Ratio Deco, The latest as of 2021 is RD 3.0, which has less emphasis on deep stops than RD 2.0.
Appropriately skilled and fit freedivers can go as deep, or deeper than, recreational scuba divers, the depth being limited only by the willingness to accept the risks; scuba diving is restricted by the level of certification. Freshwater springs, often with excellent visibility, provide good freediving opportunities but with greater risks.
The diving work associated with the recovery of all or part of ships, their cargoes, aircraft, and other vehicles and structures which have sunk or fallen into water is called salvage diving. In the case of ships it may also refer to diving to do repair work to make an abandoned or distressed but still floating vessel more suitable for towing ...
