William Hogarth Main
William "Bill" Hogarth Main is a cave diving pioneer who is best known as a developer in the 1980s, and the namesake of, the "Hogarthian gear configuration" that is a component of the " Doing It Right" (DIR) holistic approach to scuba diving. According to Jarrod Jablonski, the Hogarthian style "has many minor variations, yet its focus asserts a policy of minimalism." The configuration was refined in the 1990s, partially through the Woodville Karst Plain Project The Woodville Karst Plain Project or WKPP, is a project and organization that maps the underwater cave systems underlying the Woodville Karst Plain. This plain is a area that runs from Tallahassee, Florida, U.S. to the Gulf of Mexico and includes ... (WKPP), established in 1985 and considered among the most aggressive cave diving initiatives in the world. Main began diving in 1966 or early 1967 after completing the NAUI Open Water Course, made his first cave dive on a single tank in 1969, and switched to double tanks ...

High Springs, Florida
High Springs is a city in Alachua County, Florida, United States. It is the fourth-largest city in Alachua County and seventh-largest in North Central Florida. The population was 6,215 at the 2020 census. History The present-day area of High Springs was first settled on a permanent basis by English-speaking people during the late 1830s. One of the earliest settlements in the vicinity was at Crockett Springs, located about three miles east of present-day High Springs. Settlers who were living there during the 1840s included Fernando Underwood and Marshal Blanton. A discernible town began to develop in the early 1880s after the Savannah, Florida & Western Railway was constructed and several phosphate mines were established. A railroad station and a post office called Santaffey were established in 1884. The post office was renamed Santa Fe a few months later, then Orion the next year, and in 1888 it became High Springs, and the town was officially incorporated in 1892. The town had ...

Cave Diving
Cave-diving is underwater diving in water-filled caves. It may be done as an extreme sport, a way of exploring flooded caves for scientific investigation, or for the search for and recovery of divers or, as in the 2018 Thai cave rescue, other cave users. The equipment used varies depending on the circumstances, and ranges from breath hold to surface supplied, but almost all cave-diving is done using scuba equipment, often in specialised configurations with redundancies such as sidemount or backmounted twinset. Recreational cave-diving is generally considered to be a type of technical diving due to the lack of a free surface during large parts of the dive, and often involves planned decompression stops. A distinction is made by recreational diver training agencies between cave-diving and cavern-diving, where cavern diving is deemed to be diving in those parts of a cave where the exit to open water can be seen by natural light. An arbitrary distance limit to the open water s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doing It Right (scuba Diving)
Doing It Right (DIR) is a holistic approach to scuba diving that encompasses several essential elements, including fundamental diving skills, teamwork, physical fitness, and streamlined and minimalistic equipment configurations. DIR proponents maintain that through these elements, safety is improved by standardizing equipment configuration and dive-team procedures for preventing and dealing with emergencies. DIR evolved out of the efforts of divers involved in the Woodville Karst Plain Project (WKPP) during the 1990s, who were seeking ways of reducing the fatality rate in those cave systems. The DIR philosophy is now used as a basis for teaching scuba diving from entry-level to technical and cave qualifications by several organizations, such as Global Underwater Explorers (GUE), Unified Team Diving (UTD) and InnerSpace Explorers (ISE). History The DIR approach (and name) evolved out of the Woodville Karst Plain Project (WKPP) in the mid-1990s, where the objective was conductin ...

Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...

Woodville Karst Plain Project
The Woodville Karst Plain Project or WKPP, is a project and organization that maps the underwater cave systems underlying the Woodville Karst Plain. This plain is a area that runs from Tallahassee, Florida, U.S. to the Gulf of Mexico and includes numerous first magnitude springs, including Wakulla Springs, and the Leon Sinks Cave System, the longest underwater cave in the United States. The project grew out of a cave diving research and exploration group established in 1985 and incorporated in 1990 (by Bill Gavin and Bill Main, later joined by Parker Turner, Lamar English and Bill McFaden, at the time the chairman of the NACD Exploration and Survey Committee). WKPP is the only organization currently allowed to dive some of these caves – which are all on State, Federal, or private land – due to the extreme nature of the systems and the discipline required to safely explore them, although these caves were explored extensively prior to the establishment of the WKPP. This is a con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Association Of Underwater Instructors
The National Association of Underwater Instructors (NAUI Worldwide) is a non-profit association of scuba instructors. It primarily serves as a recreational dive certification and membership organization established to provide international diver standards and education programs. The agency was founded in 1960 by Albert Tillman and Neal Hess. NAUI is headquartered in the Tampa, Florida area with dive and member instructors, resorts, stores, service and training centers, located around the world. It was officially CE and International Organization for Standardization (ISO) certified in May 2007 in all three diver levels and both instructor levels and re-certified for its scuba diving programs as meeting ISO and European Underwater Federation standards on November 24, 2015. The US Internal Revenue Service determined that NAUI be a tax-exempt non-profit educational organization in 1971. Agency standards, policies, and ethics are governed by the Association's Board of Directors, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Blending For Scuba Diving
Gas blending for scuba diving (or gas mixing) is the filling of diving cylinders with non-air breathing gases such as nitrox, trimix and heliox. Use of these gases is generally intended to improve overall safety of the planned dive, by reducing the risk of decompression sickness and/or nitrogen narcosis, and may improve ease of breathing. Filling cylinders with a mixture of gases has dangers for both the filler and the diver. During filling there is a risk of fire due to use of oxygen and a risk of explosion due to the use of high-pressure gases. The composition of the mix must be safe for the depth and duration of the planned dive. If the concentration of oxygen is too lean the diver may lose consciousness due to hypoxia and if it is too rich the diver may suffer oxygen toxicity. The concentration of inert gases, such as nitrogen and helium, are planned and checked to avoid nitrogen narcosis and decompression sickness. Methods used include batch mixing by partial pressure o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
