The Professional Association of Diving Instructors (PADI) is a recreational diving membership and diver training organization founded in 1966 by John Cronin and Ralph Erickson. PADI courses range from entry level to advanced recreational diver certification. Further, they provide several diving skills courses connected with specific equipment or conditions, some diving related informational courses and a range of recreational diving instructor certifications. They also offer various technical diving courses. As of 2020, PADI claims to have issued 28 million scuba certifications. The levels are not specified and may include minor specialisations. Some of the certifications align with WRSTC and ISO standards, and these are recognised worldwide. Some other certification is unique to PADI and has no equivalence anywhere, or may be part of other agencies' standards for certification for more general diving skill levels.
A deep-submergence vehicle (DSV) is a deep-diving crewed submersible that is self-propelled. Several navies operate vehicles that can be accurately described as DSVs. DSVs are commonly divided into two types: research DSVs, which are used for exploration and surveying, and DSRVs, which are intended to be used for rescuing the crew of a sunken navy submarine, clandestine (espionage) missions, or both. DSRVs are equipped with docking chambers to allow personnel ingress and egress via a manhole.
Snuba is form of surface-supplied diving that uses an underwater breathing system developed by Snuba International. The origin of the word "Snuba" may be a portmanteau of "snorkel" and "scuba", as it bridges the gap between the two. Alternatively, some have identified the term as an acronym for "Surface Nexus Underwater Breathing Apparatus", though this may have been ascribed retroactively to fit the portmanteau. The swimmer uses swimfins, a diving mask, weights, and diving regulator as in scuba diving. Instead of coming from tanks strapped to the diver's back, air is supplied from long hoses connected to compressed air cylinders contained in a specially designed flotation device at the surface. Snuba often serves as a form of introductory diving, in the presence of a professionally trained guide, but requires no scuba certification.
Haenyeo are female divers in the South Korean province of Jeju, whose livelihood consists of harvesting a variety of mollusks, seaweed, and other sea life from the ocean. Known for their independent spirit and determination, haenyeo are representative of the semi-matriarchal family structure of Jeju.
Shark cage diving is underwater diving or snorkeling where the observer remains inside a protective cage designed to prevent sharks from making contact with the divers. Shark cage diving is used for scientific observation, underwater cinematography, and as a tourist activity. Sharks may be attracted to the vicinity of the cage by the use of bait, in a procedure known as chumming, which has attracted some controversy as it is claimed to potentially alter the natural behaviour of sharks in the vicinity of swimmers.
The Undersea and Hyperbaric Medical Society (UHMS) is an organization based in the US which supports research on matters of hyperbaric medicine and physiology, and provides a certificate of added qualification for physicians with an unrestricted license to practice medicine and for limited licensed practitioners, at the completion of the Program for Advanced Training in Hyperbaric Medicine. They support an extensive library and are a primary source of information for diving and hyperbaric medicine physiology worldwide.
Thomas Robert Daley is an English retired diver, YouTuber and television personality. He is an Olympic champion in the men's synchronised 10-metre platform event at the 2020 Olympics and double world champion in the FINA 10-metre platform event, winning in 2009 at the age of fifteen, and again in 2017. He is an Olympic bronze medallist in the 2012 platform event, the 2016 synchronised event, and the 2020 platform event. He won the silver medal in the men's synchronised 10-metre at the 2024 Olympics, making him the first British diver to win 5 Olympic medals. Daley also competed in team events, winning the inaugural mixed team World title in 2015, and repeating the win in 2024, his fourth World title in all. He is an Olympic champion, four-time World Champion, a two-time junior World Champion, a five-time European champion and four-time Commonwealth champion.
Constant weight without fins (CNF) is an AIDA International freediving discipline in which the freediver descends and ascends by swimming without the use of fins or without pulling on the rope or changing his or her ballast; only a single hold of the rope to stop the descent and to start the ascent is allowed. Constant weight without fins is the depth discipline of freediving that is most challenging, because of the physical effort needed to swim without assistance.
Oceanic is an American manufacturer of scuba gear. It was founded by Bob Hollis in 1972 and is based in San Leandro, California, United States. Its products include dive computers, rebreathers and a novel diving mask incorporating a heads-up-display of information.
The West Florida Argonauts are the athletic teams that represent the University of West Florida, located in Pensacola, Florida, in intercollegiate sports at the Division II level of the National Collegiate Athletic Association (NCAA), primarily competing in the Gulf South Conference (GSC) since the 1994–95 academic year. The Argonauts previously competed in the Southern States Conference of the National Association of Intercollegiate Athletics (NAIA) from 1974–75 to 1993–94, with a brief hiatus of dropping its athletics program from 1976–77 to 1979–80.

John Morgan Wells was a marine biologist, and physiologist involved in the development of decompression systems for deep diving, and the use of nitrox as a breathing gas for diving. He is known for developing the widely used NOAA Nitrox I and II mixtures and their decompression tables in the late 1970s, the deep diving mixture of oxygen, helium, and nitrogen known as NOAA Trimix I, for research in undersea habitats, where divers live and work under pressure for extended periods, and for training diving physicians and medical technicians in hyperbaric medicine.
The history of scuba diving is closely linked with the history of the equipment. By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered; open-circuit surface supplied equipment where the diver's exhaled gas is vented directly into the water, and closed-circuit breathing apparatus where the diver's carbon dioxide is filtered from the exhaled breathing gas, which is then recirculated, and more gas added to replenish the oxygen content. Closed circuit equipment was more easily adapted to scuba in the absence of reliable, portable, and economical high pressure gas storage vessels. By the mid-twentieth century, high pressure cylinders were available and two systems for scuba had emerged: open-circuit scuba where the diver's exhaled breath is vented directly into the water, and closed-circuit scuba where the carbon dioxide is removed from the diver's exhaled breath which has oxygen added and is recirculated. Oxygen rebreathers are severely depth limited due to oxygen toxicity risk, which increases with depth, and the available systems for mixed gas rebreathers were fairly bulky and designed for use with diving helmets. The first commercially practical scuba rebreather was designed and built by the diving engineer Henry Fleuss in 1878, while working for Siebe Gorman in London. His self contained breathing apparatus consisted of a rubber mask connected to a breathing bag, with an estimated 50–60% oxygen supplied from a copper tank and carbon dioxide scrubbed by passing it through a bundle of rope yarn soaked in a solution of caustic potash. During the 1930s and all through World War II, the British, Italians and Germans developed and extensively used oxygen rebreathers to equip the first frogmen. In the U.S. Major Christian J. Lambertsen invented a free-swimming oxygen rebreather. In 1952 he patented a modification of his apparatus, this time named SCUBA, an acronym for "self-contained underwater breathing apparatus," which became the generic English word for autonomous breathing equipment for diving, and later for the activity using the equipment. After World War II, military frogmen continued to use rebreathers since they do not make bubbles which would give away the presence of the divers. The high percentage of oxygen used by these early rebreather systems limited the depth at which they could be used due to the risk of convulsions caused by acute oxygen toxicity.
