A scuba set is characterized by full independence from the surface during use, by providing breathing gas carried by the diver. Early attempts to reach this autonomy were made in the 18th century by the Englishman John Lethbridge, who invented and successfully built his own underwater diving machine in 1715, but though the air supply was carried in the diving apparatus, it relied on surface ...
The timeline of underwater diving technology is a chronological list of notable events in the history of the development of underwater diving equipment.With the partial exception of breath-hold diving, the development of underwater diving capacity, scope, and popularity, has been closely linked to available technology, and the physiological constraints of the underwater environment.
The Espíritu Santo was discovered by Vida Lee Connor while scuba diving in 1966. A salvage operation by a private company in 1967 was the subject of a court case and was responsible for the Antiquities Code of Texas, passed by the state legislature in 1969.
Pasley's diving salvage operation set many diving milestones, including the first recorded use of the buddy system in diving, when he gave instructions to his divers to operate in pairs. [ 39 ] [ 41 ] In addition, the first emergency swimming ascent was made by a diver after his air line became tangled and he had to cut it free.

Before the early 1960s it was debated whether coral reefs could develop off the Texas coast; some researchers predicted the area would be too cold, or too turbid to support any extensive reef development. A series of scientific scuba diving expeditions, however, revealed that EFGB and WFGB did indeed support extensive coral reef systems. [3]
A scuba diving emergency is an incident while scuba diving, in which there is a high probability of death or severe injury if the problem is not resolved quickly. [133] A diving emergency may be related to life-support, [1] decompression stress and barotraume, [1] incapacitation or inability to cope, [134] or an acute medical problem. [116]
