life support life support system. See: Life-support system#Underwater and saturation diving habitats. Equipment vital to the short term survival of the diver. Most notably the breathing gas supply, and for saturation diving, equipment for providing a correctly pressurised environment. In some cases thermoregulatory equipment is also considered ...
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.

Temperate water is water cooler than tropical, and warmer than "cold water". For diving purposes this can be considered the temperature range in which a full wetsuit is acceptable thermal protection for most divers for most diving activities. The range of 10 to 25 °C (50 to 77 °F) could generally be considered temperate water for diving.
That doesn’t stop Pita, now 21, from being an avid scuba diver – typically thought of as a “seen activity,” where people are able to witness the vibrancy of life below the water’s surface.
Doing it Right: The Fundamentals of Better Diving page 67 says: "It is the perfect system in zero visibility as well as in crystal clear water. The DIR system requires no modification to function effectively and efficiently in different environments ... In freezing water these divers use dry gloves and thicker undergarments and possibly ...
Human factors are significant in diving because of this harsh and alien environment, and because diver life support systems and other equipment that may be required to perform specific tasks depend on technology that is designed, operated and maintained by humans, and because human factors are cited as significant contributors to diving ...
Scientific diving is the use of underwater diving techniques by scientists to perform work underwater in the direct pursuit of scientific knowledge. [11] Scientific divers are normally qualified scientists first and divers second, who use diving equipment and techniques as their way to get to the location of their fieldwork.
Scuba diver in Panama. Recreational diving may be considered to be any underwater diving that is not occupational, professional, or commercial, in that the dive is fundamentally at the discretion of the diver, who dives either to their own plan, or to a plan developed in consensus with the other divers in the group, though dives led by a professional dive leader or instructor for non ...
