This is a glossary of technical terms, jargon, diver slang and acronyms used in underwater diving Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving (other), diving, an ambiguous term with several possible meani .... The definitions listed are in the context of underwater diving. There may be other meanings in other contexts. Underwater diving can be described as a human activity – intentional, purposive, conscious and subjectively meaningful sequence of actions. Underwater diving is practiced as part of an occupation, or for recreation, where the practitioner submerges below the surface of the water or other liquid for a period which may range between seconds to the order of a day at a time, either exposed to the ambient pressure or isolated by a pressure resistant suit, to interact with the underwater environment for pleasure, ...

Outline Of Recreational Dive Sites
Reef dive sites In the context of recreational diving, a reef may be a coral reef or a bottom of predominantly consolidated inorganic material, like rocky reef, and in the broader sense includes artificial structures and even ships sunk as artificial reefs. No special equipment is needed for most reef dive sites, but sufficient skill in buoyancy and depth control is desirable so that the diver does not harm the ecosystem by clumsy impacts with the bottom or stirring up sediment. Drift diving may be optional or the default where the current is strong. Reef diving regions are geographical regions of arbitrary size known for including more than one named reef dive site, while a reef dive site is a specific part of a reef known by a name, which recreational divers visit to dive. Wall diving is a form of reef diving, where The main characteristic of the sites is that the terrain is predominantly near vertical. The height of the wall can vary from a few me ...

Diving Stage
There are several categories of decompression equipment used to help divers Decompression practice, decompress, which is the process required to allow divers to return to the surface safely after spending time underwater at higher ambient pressures. Decompression obligation for a given dive profile must be calculated and monitored to ensure that the risk of decompression sickness is controlled. Some equipment is specifically for these functions, both during planning before the dive and during the dive. Other equipment is used to mark the underwater position of the diver, as a position reference in low visibility or currents, or to assist the diver's ascent and control the depth. Decompression may be shortened ("accelerated") by breathing an oxygen-rich "decompression gas" such as a nitrox blend or pure oxygen. The high partial pressure of oxygen in such decompression mixes produces the effect known as the oxygen window. This decompression gas is often carried by scuba divers i ...

Underwater Diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving (other), diving, an ambiguous term with several possible meanings, depending on context. Immersion in water and exposure to high ambient pressure have Physiology, physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well-adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. 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 (freediving) or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness ...

Action (philosophy)
In philosophy, an action is something an Agency (philosophy), agent does. Actions contrast with events which merely happen to someone and are typically performed for a Goal, purpose and guided by an intention. The first question in the Action theory (philosophy), philosophy of action is to determine how actions differ from other forms of behavior, like Reflex, involuntary reflexes. According to Ludwig Wittgenstein, it involves discovering "What is left over if I subtract the fact that my arm goes up from the fact that I raise my arm". A common response to this question focuses on the agent's intentions. So driving a car is an action since the agent intends to do so, but sneezing is a mere behavior since it happens independent of the agent's intention. The dominant theory of the relation between the intention and the behavior is ''causalism'': driving the car is an action because it is ''caused'' by the agent's intention to do so. On this view, actions are distinguished from other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
