'''Underwater diving''' – as a human activity, is the practice of descending below the water's surface to interact with the environment.

== What ''type'' of activity is underwater diving? ==

Underwater diving can be described as all of the following:
*A [[Philosophy:Action|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, competitive sport, or as a means to reach a work site for profit or in the pursuit of knowledge, and may use no equipment at all, or a wide range of equipment which may include breathing apparatus, environmental protective clothing, aids to vision, communication, propulsion, maneuverability, buoyancy and safety equipment, and tools for the task at hand.

== Diving activity, by type ==

=== Modes of underwater diving ===
<noinclude>[[File:Marin du commerce en formation de plongeur de bord à l'I.N.P.P..JPG|thumb|Surface-supplied diver with helmet, bailout set and umbilcal cable]]</noinclude>
There are several modes of diving distinguished by the equipment and procedures used:
* Freediving – Underwater diving without breathing apparatus
* Scuba diving – Swimming underwater breathing gas carried by the diver
* Surface-supplied diving – Underwater diving breathing gas supplied from the surface
* Saturation diving – Diving for periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas
* Atmospheric pressure diving – Diving where the diver is isolated from the ambient pressure by an articulated pressure resistant diving suit or in a crewed submersible
* Unmanned diving – Diving by mechanisms under the direct or indirect control of remote human operators for observation, data collection or manipulation of the environment using on-board actuator devices

=== Diving skills and procedures ===
