The Underwater World "There you are, totally weightless, quietly soaring just above the sea floor with only the smallest amount of physical exertion. Small fish come out of their holes to look at you. How about that? You are the curiosity. You are the thing that does not belong. Perhaps this is why you dive. You are taking part in exploring man's last ecological frontier. The very thought would excite anyone whose blood still flows in his veins. The diver is the observer, he looks at everything he can. He totally forgets the outside world" (Reseck 4). When I first read this piece, I got goosebumps. For years man has explored this vast universe, spending millions of dollars, and only making a tiny scratch on its surface. For me, to be able to explore a world completely different from mine sounds like an opportunity of a lifetime. When I had to choose a topic for my senior project, scuba diving was the most compelling of all. This paper is about the development and use, the techniques, and the physiological concerns of scuba diving. Man underwater dates all the way back to the Iliad, but sports diving for fun and for a profession is fairly new. If one has ever been underwater, he should know that breathing is impossible. In the early 1940's, Jaques Yves-Cousteau, a Frenchman, developing something that is now a very important asset to scuba diving. It is known to us as a "regulator." The regulator conserved air by releasing only the amount of air the Korell 2 diver needed to breathe. This increased the time the diver could stay down on one tank of air to about one hour if he were in shallow depths. Cousteau's regulator was simple and inexpensive and marked the beginning of the sport of scuba diving. The sport grew somewhat slo... ... middle of paper ... ...ery complex topic due to the scientific side of it. There are many scientific laws and there are many restrictions related to it. The only drawback of learning how to scuba dive is the cost. But if you are willing to spend about $450 and want to learn Korell 9 a lot more about scuba diving than the underwater portion, then by all means--go ahead. After all, it is a completely different world down there. Bibliography: Bibliography Counsilman and Drinkwater. Beginning Skin and Scuba Diving. Belmont, CA: Wadsworth Publishing Company, Inc. 1964.

In this essay, the author

  • Opines that scuba diving is the most compelling topic for their senior project, citing jaques yves-cousteau's "regulator."
  • Describes the invention of the "wet suit," which strapped a thin layer of water next to the diver's body, which heated up to body temperature.
  • Explains that scuba diving can be dangerous if not approached safely. the pike surface dive starts from a prone position on the surface.
  • Explains that the mask, the snorkel, and the fins are three of the most important tools in diving.
  • Explains that the snorkel is a critical tool for breathing underwater. the fins make you move through the water faster and less rigorously.
  • Explains the importance of the "buddy system" when diving and recommends putting on fins, mask, and snorkel and walking slowly backward to the middle of a shallow area.
  • Explains the two major forms of barotrauma in scuba diving: internal and external squeeze.
  • Explains that equipment squeezes are caused by the inability to equalize the air pressure between the mask and the face on the diver's descent.
  • Concludes that scuba diving is a complex sport due to the scientific side of it.
  • Cites counsilman and drinkwater. beginning skin and scuba diving. belmont, ca: wadsworth publishing company, inc.
