Deep-sea diving is sometimes regarded as SCUBA(Self-contained under water breathing apparatus) diving. Since the introduction of the apparatus, the sport has grown in popularity and is enjoyed by pleasure seekers, treasure hunters, researchers and sportsmen world-wide. Deep-sea diving requires an in-depth knowledge of the effects of extreme pressure on the body, as well as the waters within which one is diving. To dive locally, one needs to acquire a licence, commonly referred to as a “C-Card” or an “open-water diver’s card”. Other than the aid of the oxygen tank and a respirator, divers also make use of goggles to help them see underwater. Flippers are also required to help them move in the waters effortlessly.
This sport used to be known as 'Aqualung' and was developed by Emile Gagnan and Jacques Cousteau in 1943. Through them, they invented a breathing gas consisting of a high pressure diving cylinder and a diving regulator. Today, deep-sea diving is used for various activities, some commercial and recreational, while others are for professional endeavours. They includes military/naval diving, police diving, rescue and recovery diving, scientific diving, technical diving (cave diving, cavern diving, ice diving), etc.
What attracts them
Marine life and the mystery it carries - within the underwater world - has become a huge attraction amongst divers. The experience of being able to swim, observe and explore colourful sea creatures and other marine lifeform was considered to be hard to come by. As a result, the sport became popular, and an increasing number of diving resorts have appeared over the last few years. However, such an phenomenon has its consequences. Diving activities have led to marine pollution and disturbance to underwater wildlife - hence affecting its ecosystem.
Apart from standard medical packaging, medical equipment and facilities should be made accessible easily and quickly within the diving vicinity. This is becuase, incidents such as respiratory problems, boat accidents, decompression sickness, unconsciousness and oxygen poisoning are some of the possible dangers that may occur. Finally, be familiar with the waters that you are diving in, as well as the marine life that you are likely to encounter.
