As diving is an activity that is considered to put the diver at a higher than normal risk to health, in the UK all diving at work, including scientific diving, is regulated through the Diving at Work Regulations, 1997 and the associated approved codes of practice, which are implemented by the Health and Safety Executive. The code of practice ...
With naval research funding constrained by Vietnam War combat requirements, [2] it was four years later before SEALAB III used the refurbished SEALAB II habitat placed in water three times deeper. Five teams of nine divers were scheduled to spend 12 days each in the habitat, testing new salvage techniques and conducting oceanographic and ...
The swath of seafloor covered in a single pass by side-scan sonar is relatively wide and therefore it is a relatively efficient search system with a high confidence for detecting and identifying a target, and is considered one of the most effective tools for underwater search. [9]: Ch. 2
The usual methods for survey and mapping of underwater caves are dead reckoning and direct measurements of distance, compass direction and depth, by diving teams of two or three scuba divers, who record azimuth of the cave line, measurements of height, width, depth, and slope at intervals along the line, generally using a permanent guide line ...
Compared with methods of land survey and excavations, archaeological diving has distinct advantages and disadvantages. The equipment, such as air compressors, exposure suits, compressed air cylinders, masks and fins, together with the training required for proper scientific diving is considerably more expansive than the training and equipment usually used during land excavations, contributing ...
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.
Professional diving (commercial diving, diving for research purposes, or for financial gain) involves working underwater. Public safety diving is the underwater work done by law enforcement, fire rescue, and underwater search and recovery dive teams. Military diving includes combat diving, clearance diving and ships husbandry.
This way, it is assessed what advantages and disadvantages they have and for what research goals they may be used. These descriptions and evaluations depend on philosophical background assumptions. Examples are how to conceptualize the studied phenomena and what constitutes evidence for or against them.
