This is a glossary of technical terms, jargon, diver slang and acronyms used in underwater diving.The definitions listed are in the context of underwater diving.
In professional diving, a depth that requires special equipment, procedures, or advanced training may be considered a deep dive. Deep diving can mean something else in the commercial diving field. For instance early experiments carried out by COMEX using heliox and trimix attained far greater depths than any recreational technical diving. One ...
In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep dives.
Sea snakes, crocodiles, and marine iguanas only dive in inshore waters and seldom dive deeper than 10 meters (33 feet). Some of these groups can make much deeper and longer dives. Emperor penguins regularly dive to depths of 400 to 500 meters (1,300 to 1,600 feet) for 4 to 5 minutes, often dive for 8 to 12 minutes, and have a maximum endurance ...
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.
Deep, decompression diving is necessarily required to effect penetration diving on the WKPP. Extended dive duration and surveys of previously unexplored parts of the cave system exposed divers to unprecedented exposures. Diving of this type is subject to increased level of risk and increased risks require more stringent mitigation.
Sea snakes, crocodiles and marine iguanas only dive in inshore waters and seldom dive deeper than 10 m, but both of these groups can make much deeper and longer dives. Emperor penguins regularly dive to depths of 400 to 500 m for 4 to 5 minutes, often dive for 8 to 12 minutes and have a maximum endurance of about 22 minutes.
Recreational scuba diver The undersea kelp forest of Ana Capa off of the coast of Oxnard, California Diver looking at a shipwreck in the Caribbean Sea. Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance.
