Day3!!! today i learned all about the Aquarius system and how it is run. I have been diving since i was a little girl, but it still baffles me how i can stay at the bottom of the ocean for so long. well, turns out that type of diving we do allows us to stays under the water longer. saturation diving is a key part to out survival down here. saturation diving is is based on the principle that the pressure of the dissolved gas in the blood and tissues is the same as that of the gas in the lungs. Basically, a diver goes down to a depth, perhaps 300 feet, and remains there until no more gas can dissolve in the tissues -- the tissues are saturated with nitrogen. Once the saturation point has been reached, the time required for decompression will be the same no matter how much longer the diver stays at that depth, whether it be a minute, an hour, a day or a week.The disadvantages of saturation diving however, are pain or expanding and or contracting trapped gases, potentially leading to damage. Gas toxic ides are also a huge side effect,and the risk of getting "the bends".
