Underwater diving is the practice of descending below the water's surface to interact with the environment. It encompasses a variety of activities, including scuba diving, freediving, and snorkeling.

Types of Underwater Diving[edit]

Scuba Diving[edit]

Scuba diving involves using a self-contained underwater breathing apparatus (scuba) to breathe underwater. Divers carry their own source of breathing gas, usually compressed air, allowing them greater freedom of movement.

Freediving[edit]

Freediving is diving without the use of breathing apparatus, relying on holding one's breath until resurfacing. It is often practiced as a competitive sport or recreational activity.

Snorkeling[edit]

Snorkeling involves swimming on or through a body of water while equipped with a diving mask, a shaped tube called a snorkel, and usually fins. It allows the snorkeler to observe underwater attractions for extended periods with relatively little effort.

Surface-supplied Diving[edit]

Surface-supplied diving uses equipment supplied with breathing gas from the surface, either from a diving bell or a diving support vessel. This method is often used in commercial diving operations.

Hazards of Underwater Diving[edit]

Underwater diving presents several potential hazards, including:

Decompression sickness: A condition caused by dissolved gases coming out of solution into bubbles inside the body due to rapid ascent.
Barotrauma: Injury caused by pressure differences between the inside and outside of the body.
Nitrogen narcosis: A reversible alteration in consciousness that occurs while diving at depth.

Diving Equipment[edit]

Divers use a variety of equipment to ensure safety and enhance their underwater experience:

Diving mask: Allows divers to see clearly underwater.
Fins: Aid in efficient movement through the water.
Wetsuit: Provides thermal insulation and protection.
Buoyancy compensator: Helps divers maintain neutral buoyancy.
Diving regulator: Delivers breathing gas from the tank to the diver.

-'''Underwater Diving''' is the practice of descending below the water's surface to interact with the environment. Immersion in water and exposure to high ambient pressure have 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.

-===Scuba Diving===
+'''Underwater diving''' is the practice of descending below the water's surface to interact with the environment. It encompasses a variety of activities, including [[scuba diving]], [[freediving]], and [[snorkeling]].
-[[Scuba diving]] is a form of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba), which is completely independent of surface supply, to breathe underwater.
-===Free-diving===
+== Types of Underwater Diving ==
-[[Free-diving]], also known as breath-hold diving or skin diving, is a form of underwater diving that relies on the diver's ability to hold their breath until resurfacing rather than on the use of a breathing apparatus such as scuba gear.
-===Technical Diving===
+=== Scuba Diving ===
-[[Technical diving]] is a form of scuba diving that exceeds the scope of recreational diving (although the vast majority of technical divers dive for recreation and personal satisfaction). Technical divers require advanced training, extensive experience, and specialized equipment.
+[[Scuba diving]] involves using a self-contained underwater breathing apparatus (scuba) to breathe underwater. Divers carry their own source of breathing gas, usually compressed air, allowing them greater freedom of movement.
-===Commercial Diving===
+=== Freediving ===
-[[Commercial diving]] involves working underwater using surface supplied diving equipment. This type of diving is often used for underwater welding, offshore construction, dam maintenance, and harbor and ship maintenance.
+[[Freediving]] is diving without the use of breathing apparatus, relying on holding one's breath until resurfacing. It is often practiced as a competitive sport or recreational activity.
-===Military Diving===
+=== Snorkeling ===
-[[Military diving]] involves military forces performing tasks such as reconnaissance, demolition, salvage, or combat. Military divers may also perform non-combat roles in support of naval operations.
+[[Snorkeling]] involves swimming on or through a body of water while equipped with a diving mask, a shaped tube called a snorkel, and usually fins. It allows the snorkeler to observe underwater attractions for extended periods with relatively little effort.
-===Cave Diving===
+=== Surface-supplied 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 and recovery of divers lost while diving for one of these reasons.
+[[Surface-supplied diving]] uses equipment supplied with breathing gas from the surface, either from a diving bell or a diving support vessel. This method is often used in commercial diving operations.
-==Safety and Risks==
+== Hazards of Underwater Diving ==
-Underwater diving is considered a high-risk activity. Divers face specific physical and health risks when they go underwater or use high pressure breathing gas. The most common risks include drowning, decompression sickness, arterial air embolism, and other diving related disorders.
