I have been underwater diving once, and it was beautiful.
Underwater diving
Underwater diving, as a human activity, 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.
In ambient pressure diving, the
and for supplying power to the submersible power pump. As for the second raft, it was used to carry and store diving gears and wet suits. The last raft served the role of lifting and delivering the artifacts that were obtained from the underwater site. Dredging systems were used to clear away the mud, sand and coral that covered the ship. Once artifacts have been lifted from the site, they were immediately put in a saltwater bath. This allowed the limestone and coral to keep its layers from being damaged. Archaeologists
