These are not dangerous in themselves, but may result in the diver getting lost, swimming into an entrapment hazard or under an overhang, violating a decompression obligation, or running out of breathing gas. Lack of light or absorption of light by turbidity. A dive light can provide light if the visibility is sufficient.
Diving safety is the aspect of underwater diving operations and activities concerned with the safety of the participants. The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team.
These range from the toxic effects of oxygen at high partial pressure, [40] through buildup of carbon dioxide due to excessive work of breathing and increased dead space, [41] to the exacerbation of the toxic effects of contaminants in the breathing gas due to the increased concentration at high pressures, [42] and include effects on the ...
In cold water immersions, such as by falling through thin ice, cold shock response is perhaps the most common cause of death. [1] Also, the abrupt contact with very cold water may cause involuntary inhalation, which, if underwater, can result in fatal drowning .
Underwater explosions using dry ice and liquid nitrogen are captured in high definition slow motion by The Backyard Scientist.
What's more inaccessible than the deep sea? A deep sea blanketed in a thick shell of ice. Yet during a daunting October 2021 mission called the HACON project, a group of over two dozen scientists ...
The researchers drilled into the ice, careful to avoid contaminating any water samples during extraction, and analysis subsequently revealed a treasure trove of microbiota.
Ice diving is a type of penetration diving where the dive takes place under ice. [57] [39] Because diving under ice places the diver in an overhead environment typically with only a single entry/exit point, it requires special procedures and equipment. Ice diving is done for purposes of recreation, scientific research, public safety (usually ...
