Here's why divers shower, pat down with damp towels between dives at the 2024 Paris Olympic Games. ... "And in a sport as precise as diving, this is even more important." Divers are also seen ...
Scuba diving tourism is a growth industry, and it is necessary to consider environmental sustainability, as the expanding impact of divers can adversely affect the marine environment in several ways, and the impact also depends on the specific environment. Tropical coral reefs are more easily damaged by poor diving skills than some temperate ...
underwater diving before flying – divers who ascend to altitude soon after a dive increase their risk of developing DCS even if the dive itself was within the dive table safe limits. Dive tables make provisions for post-dive time at surface level before flying to allow any residual excess nitrogen to outgas.
A recompression chamber is used to treat some diving disorders and for training divers to recognise the symptoms. Diving disorders are medical conditions specifically arising from underwater diving. The signs and symptoms of these may present during a dive, on surfacing, or up to several hours after a dive.
Free-flow diving helmets avoid the dead space problem by supplying far more air than the diver can use, and eliminating the oro-nasal compartment. This makes the whole interior of the helmet effectively fresh air, as it is adequately flushed during and after each exhalation at the cost of significantly higher gas usage in open circuit systems.
Abandonment at surface after a boat dive Diver lost at sea on the surface after a dive, with risk of exposure, drowning and dehydration. Diver separated from boat cover due to poor visibility at surface or strong underwater currents. Diver left behind due to inaccurate check by boat crew. Diver unable to return to unattended boat.
the distance of the diver from the diving apparatus throughout the dive (a diver must not be dangerously close, should not be too far away, but should ideally be within 2 feet (0.61 m) of the platform) the properly defined body position of the diver according to the dive being performed, including pointed toes and feet touching at all times
The science of underwater diving includes those concepts which are useful for understanding the underwater environment in which diving takes place, and its influence on the diver. It includes aspects of physics, physiology and oceanography. The practice of scientific work while diving is known as Scientific diving.
