Aqua-Lung was the first open-circuit, self-contained underwater breathing apparatus to achieve worldwide popularity and commercial success. This class of equipment is now commonly referred to as a twin-hose diving regulator, or demand valve. The Aqua-Lung was invented in France during the winter of 1942–1943 by two Frenchmen: engineer Émile Gagnan and Jacques Cousteau, who was a Naval Lieutenant. It allowed Cousteau and Gagnan to film and explore underwater more easily.
Wreck diving is recreational diving where the wreckage of ships, aircraft and other artificial structures are explored. The term is used mainly by recreational and technical divers. Professional divers, when diving on a shipwreck, generally refer to the specific task, such as salvage work, accident investigation or archaeological survey. Although most wreck dive sites are at shipwrecks, there is an increasing trend to scuttle retired ships to create artificial reef sites. Diving to crashed aircraft can also be considered wreck diving. The recreation of wreck diving makes no distinction as to how the vessel ended up on the bottom.
Fabien Cousteau is an aquanaut, ocean conservationist, and documentary filmmaker. As the first grandson of Jacques Cousteau, Fabien spent his early years aboard his grandfather's ships Calypso and Alcyone, and learned how to scuba dive on his fourth birthday. From 2000 to 2002, he was Explorer-at-Large for National Geographic and collaborated on a television special aimed at changing public attitudes about sharks called "Attack of the Mystery Shark". From 2003 to 2006, he produced the documentary "Mind of a Demon" that aired on CBS. With the help of a large crew, he created a 14-foot, 1,200-pound, lifelike shark submarine called "Troy" that enabled him to immerse himself inside the shark world.
Rodney Winston Fox is an Australian film maker, conservationist, survivor of an attack by a great white shark, and one of the world's foremost authorities on that species. He was inducted into the International Scuba Diving Hall of Fame in 2007. He was born in Adelaide.
The 1992 cageless shark-diving expedition was the world's first recorded intentionally cageless dive with great white sharks, contributing to a change in public opinions about the supposed ferocity of these animals.
Canoe diving and Kayak diving are recreational diving where the divers paddle to a diving site in a canoe or kayak carrying all their gear in or on the boat to the place they want to dive. Canoe or kayak diving gives the diver independence from dive boat operators, while allowing dives at sites which are too far to comfortably swim, but are sufficiently sheltered.
Ronald Josiah Taylor, was an Australian shark expert, as is his widow, Valerie Taylor. They were credited with being pioneers in several areas, including being the first people to film great white sharks without the protection of a cage. Their expertise has been called upon for films such as Jaws, Orca and Sky Pirates.
Shark tourism is a form of eco-tourism that allows people to dive with sharks in their natural environment. This benefits local shark populations by educating tourists and through funds raised by the shark tourism industry. Communities that previously relied on shark finning to make their livelihoods are able to make a larger profit from diving tours while protecting the local environment. People can get close to the sharks by free- or scuba diving or by entering the water in a protective cage for more aggressive species. Many of these dives are done by private companies and are often baited to ensure shark sightings, a practice which is highly controversial and under review in many areas.
Bob Halstead, has made significant contributions to the sport of scuba diving in a multitude of capacities: photographer, author of eight diving books, early innovator in the development of dive tourism, pioneer in the dive liveaboard industry, diving instructor and educator, marine-life explorer and influential diving industry commentator. An ardent diver since 1968, Halstead has over 10,000 logged dives.
A total of 24 people have been killed by sharks in South Australian waters since the establishment of the colony in 1836. Prior to 2014, there had been 82 recorded shark attacks in South Australia. 20 of those have involved a single fatality. Victims were involved in a range of aquatic activities, including surfing, diving, spear-fishing, snorkeling, boating and swimming. Six of the fatalities occurred off the coast of greater metropolitan Adelaide, with the remainder distributed across South Australia's extensive coastline. Many of the fatal attacks have been attributed to great white sharks.
Blue Water, White Death is a 1971 American documentary film about sharks, which was directed by Peter Gimbel and James Lipscomb. It received favourable reviews and was described as a "well produced odyssey" and "exciting and often beautiful". It screened theatrically and was broadcast on television at various times during the 1970s and 1980s. The film was re-released on DVD in 2009.
Emma Forster is a South Australian television presenter, director of tourist attraction Swim with the Tuna and advisor for the company, Oceanic Victor. She lives in Port Lincoln where she has developed several properties. She has worked as a presenter on the seafood, fishing and boating television program Out of the Blue, is a friend and business advisor to multi-millionaire tuna rancher Tony Santic and is a former girlfriend of retired South Australian treasurer, Kevin Foley.
The following outline is provided as an overview of and topical guide to underwater diving:
Diving support equipment is the equipment used to facilitate a diving operation. It is either not taken into the water during the dive, such as the gas panel and compressor, or is not integral to the actual diving, being there to make the dive easier or safer, such as a surface decompression chamber. Some equipment, like a diving stage, is not easily categorised as diving or support equipment, and may be considered as either.
Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
Scuba diving tourism is the industry based on servicing the requirements of recreational divers at destinations other than where they live. It includes aspects of training, equipment sales, rental and service, guided experiences and environmental tourism.
The environmental impact of recreational diving is the effects of recreational scuba diving on the underwater environment, which is largely the effects of diving tourism on the marine environment. It is not uncommon for highly trafficked dive destinations to have more adverse effects with visible signs of diving's negative impacts due in large part to divers who have not been trained to sufficient competence in the skills required for the local environment, an inadequate pre-dive orientation, or lack of a basic understanding of biodiversity and the delicate balance of aquatic ecosystems. There may also be indirect positive effects as the environment is recognised by the local communities to be worth more in good condition than degraded by inappropriate use, and conservation efforts get support from dive communities who promote environmental awareness, and teach low impact diving and the importance of respecting marine life. There are also global coral reef monitoring networks in place which include local volunteer divers assisting in the collection of data for scientific monitoring of coral reef systems, which may eventually have a net positive impact on the environment.
Valerie May Taylor AM is an Australian conservationist, photographer, and filmmaker, and an inaugural member of the diving hall of fame. With her husband Ron Taylor, she made documentaries about sharks, and filmed sequences for films including Jaws (1975).
Open Water 3: Cage Dive is a 2017 Australian found footage survival horror film directed and written by Gerald Rascionato and released by Lionsgate as part of the Open Water film series, although the film is a stand-alone sequel and only connects to the other films in theme, not continuity. It follows a trio of Americans on vacation in Australia who are also filming an audition tape for an extreme reality TV show on a cage diving excursion. Before they know it, a rogue wave capsizes and sinks their boat leaving them stranded in the ocean. The film is presented as a mockumentary and perpetuated as true events; though most of the film is first person footage from the characters with time stamps throughout the film, in the vein of Paranormal Activity. The film bears similarities to another 2017 shark attack survival film featuring a cage dive excursion gone wrong, 47 Meters Down. The method of "cage dive disaster" in each film differs with Open Water 3: Cage Dive involving a rogue wave capsizing the boat while the former film sees a rusty winch break, trapping the protagonists underwater within the cage. The notable difference between these two films is that Cage Dive does not keep its protagonists within the cage, but rather leaves them in the open water among hungry sharks.
