Human activity in the area also accounts for a significant amount of pollution. how is the former tourism activity done? It is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba), which is completely independent of surface supply, to breathe underwater. what accessories are required to do this? Various surface detection aids may be carried to help surface personnel spot the diver after ascent. In addition to the surface marker buoy, divers may carry mirrors, lights, strobes, whistles, flares or emergency locator beacons.

Scuba diving [SEP] Depth range
Professional diving usually limits the allowed planned decompression depending on the code of practice, operational directives, or statutory restrictions. Depth limits depend on the jurisdiction, and maximum depths allowed range from to more than , depending on the breathing gas used and the availability of a decompression chamber nearby or on site. Commercial diving using scuba is generally restricted for reasons of occupational health and safety. Surface supplied diving allows better control of the operation and eliminates or significantly reduces the risks of loss of breathing gas supply and losing the diver. Scientific and media diving applications may be exempted from commercial diving constraints, based on acceptable codes of practice and a self-regulatory system.
