 * The word 'Scuba' is the abbreviation of Self Contained Underwater Breathing Apparatus. Hence, it means swimming under water using SCUBA. a cylinder of compressed gas to breathe (usually air, but sometimes other gases to stay underwater much longer, often for hours) and other equipments such as face masks, breathing regulators, buoyancy devices, fins and gauges.


 * Because of the nature of this activity, danger is a real concern. You are placing yourself in an unfamiliar environment (which is part of the fun!) and so you need not only training and good equipment, but you also need to know safety principles.

 * Most would agree that it's for the sheer enjoyment of experiencing the underwater world. This world is a vastly unexplored environment for many people. Be it the beautiful and brightly colored marine life or the thrill of watching the power and grace of a school of sharks or discovering a cave and even artifacts such as a sunken ship, it is incredibly addictive because there are endless dive sites around the world.
 * In Scuba Diving you are using a Self, Contained, Underwater, Breathing, Apparatus, to breathe underwater for a epoch of time. While staying submerged using SCUBA, you have to use Scuba gear: a B.C.D. Fins, a Mask, Wet Suit, Regulater, Computer, Tank, Octopus, and Snorkel.
 * Jacques Cousteau was the inventor of one of the original designs of the "Aqualung"
 * Cousteau's Aqualung is marketed throughout: France in 1946, Great Britain in 1950, Canada in 1951, and USA in 1952.
 * In 1981,: Stephen Porter, Len Whitlock and Erik Kramer set the lowest diving record at 2250 ft and lived in an eight ft. diameter chamber for 43 days breathing in a mixture of: oxygen, helium, and nitrogen.
 * Deep sea diving was the first form of underwater diving staying submerged below the surface, and it has been around for hundreds of years. The Greeks were the first people on record to have used underwater diving, "Deep Sea Diving." Their main purpose for Deep Sea Diving was to find buried treasure in the ocean, but the attempt of this was life threatening. They only allowed the strongest atheletes, and the best swimmers to do this, or they wouldn't survive.

When getting started, you should check your tank to make sure there is nothing in the way of the the O-Ring of the valve to make sure its clear. After that you have to lower the Buoyancy Control Device (B.C.D.) onto your tank and attach it to it. Once you have that attached to it, you have to attach you regulator to the valve of the tank, making sure that the second stage in in your right hand, while your diving computer is in your left hand. Then the air pressure must be relieved into the regulator by putting the computer away or up against the tank and turning the valve.
 * It is an extremely dangerous sport that is used with lots of per-cautions.

 * Outer spaces is more explored then the ocean, so no one knows what could be found in the depths of the ocean.

The beautiful colors along with the marine life, are examples of the true beauty of the ocean.
 * Also there are so many historical artifacts that have not yet been examined such as: sunken ships, underwater caves, and the remains of historic animals at the bottom the ocean.
