After two years of recreational diving I have learned some of the ins and outs of the dive community. Diving has become such an enjoyable experience for me that I have decided to make a career change and work towards my dream of being a commercial diver. Before making such a life altering decision, it is important to understand the differences between the two in order to further understand the depth of my decision. In this essay, I will compare portions of recreational diving to its equivalent in technical diving. I will discuss equipment, locations and careers associated with each to assist in better understanding their differences.
In recreational scuba diving there is a laundry list of available equipment to fit nearly every underwater need. One of the most important pieces of equipment a recreational diver uses is the BCD or buoyancy control device. The BCD is an adjustable inflation vest worn by a diver to increase or decrease their buoyancy during a dive. The BCD is hooked to the regulator or “Octopus” which serves as a junction point for air accessories. The BCD usually comes complete with safety features like an emergency dump valve. Safety features like these help to prevent BCD malfunctions, such as runaway accents, by allowing the diver to release the air out of the vest. Attached to the regulator along with the BCD are air pressure gauges and two breathing apparatuses. One breathing apparatus is used for normal breathing function and the other is set in a known location in the case of an emergency or disorientation. Recreational divers also have a choice between wearing a neoprene wet suit, which keeps a diver warm by retaining a layer of water next to the body, or dry suits that use a layer of air for buoy...

Throughout this essay we have had a chance to look at the two major types of underwater diving. We have a better understanding of the differences in the equipment used, the locations that each may be performed, and the career opportunities available to a person with the proper credentials.

The First five weeks the student’s learn life saving, knot tying, underwater knot tying, basic first aid, and surf passages in small inflatable boats. Along with this is a 50-yard underwater swim, which must be completed and the students are often revived when they pass out. Also throughout out the whole six months of BUD/S (Basic Underwater Demolition School), the Seal Teams go through many torturous events and lessons. One of these being surf torture. This is where the entire class must wade into the surf zone to their waistline, then sit down with arms linked. Just to let you know the water in Coronado, California never gets above sixty-eight degrees during the summer and fifty-eight degrees during the winter. There the men with linked arms will sit there for hours at a time, soon the cold sucks out all of their body warmth and the whole class is shivering in unison as the waves crash over there heads.
Sharks have also been subjected to medical research, games and competitions, jewellery, souvenirs and cosmetics. We need to take into consideration that sharks play a vital role in the natural world that we live in. it is imperative that we look after these majestic creatures and ensure they remain protected. We need to be aware of the dangers of sharks, swim in protected areas where there are shark nets, and do not swim after dark in the sea (especially not alone) as the sea is the sharks home. Humans should also be wearing wet suits as protection in the ocean. The sea is where they live, they swim freely and they eat – they do not particularly target humans but rather prey on food that is available to them in their habitat.

Biomechanics is the overall topic that will be discussed throughout the presentation, this incorporates a brief discussion about water resistance, propulsion and buoyancy. Under lifesaving, appropriate techniques and the choice of stroke for the Timed Tow will be analyzed and justified.
Scuba diving itself can be challenging at times. Imagine having a difficult task, like welding, to perform at the same time as scuba diving. This is a task that can cost you your life if not done correctly and as safely as possible.
Review: The opportunity and endeavor of exploring the Earth’s oceans can reap great rewards for mankind and unravel many of the mysteries that the Earth has left to discover.
Cold water is the key aspect in the phenomenon called the mammalian diving reflex. This reflex has been beneficially used for thousands of years by whales, dolphins, seals and other mammals that inhabit the frigid waters of the world. The diving reflex slows heart rate and causes peripheral vasoconstriction to keep blood and oxygen to the brain and other vital core organs. This reflex allows these mammals to conserve oxygen and stay submerged over longer periods of time, providing them more time for finding food, protection and travel.
This force now can be used by the diver not only to go up, but to rotate and therefore perform various dives.
The fitter we are the more we can enjoy our diving. Think back to your earliest dives and how fast you used your air until you learned to control your breathing. The less often we breathe the longer our air supply will last. Being fit our breathing will be less rapid as we exert ourselves. This could easily add another 10 to 15 minutes more to each dive. Multiply that by the number of dives you do in a year and you can see that it is a substantially additional bottom time. As in any type of physical activit...
The deep sea is one of the most hostile environments in the world, which a living organism is subjected to. As you progress from the surface (the epipelagic zone) through to the abyssopelagic zone near the basin of the ocean; the environmental characteristics begin to alter dramatically. Light, pressure, oxygen, temperature and food are abiotic factors that have all led to the fascinating adaptations of deep sea life. Pressure alone increases by 1 atmosphere for each 10m in depth which is an astonishing rate. The deep sea temperature remains between 2-4°c, which is just another factor inhabitants must overcome in order to survive, along with a reduced quantity and accessibility of essential factor’s like ;oxygen, food and light[3].
Allows divers to dive deeper and stay submerged longer. Scuba comes a long way from other forms of diving by using an air-tank and regulator. This is what allows them to stay under longer and dive deeper. Scuba originally began with military and commercial applications, where it is still used today. But now, by far the largest group of divers is “Recreational Divers”. These dives are practiced at depths of less than 130 feet, from these depths, divers can make a straight ascent to the surface. Diving beyond this limit requires advanced training. (Lawrence, 4)
Several forces play significant roles in the movement of the human body through the water. The forces are drag, lift, gravity and buoyancy. Lift and drag are the main propulsive forces that are used by swimmers. Resistance, known as drag, can be broken into three main categories: frontal resistance, skin friction, and eddy resistance. The effect of buoyancy in swimming is best described by Archimedes’ principle: a body fully or partially submerged in a fluid is buoyed up by a force equal to the weight of the fluid that is displaced by the body.1 This effectively negates any effects that gravity might have on a swimmer. The rare exception to this is a swimmer with very little body fat, and this is overcome by keeping the lungs inflated to a certain degree at all times.
Snorkeling is one of the most common underwater activities now base on most people can go snorkeling which has lesser requirements than other underwater activities. The equipment of snorkeling are only a diving tube, a set of flippers and a mask. The people of people snorkeling was that people tried to collect some
The topic of my personal project is something that I have great interest in which is diving. From a young age I have been always fascinated by the wonders of nature especially the ocean and the various amount of creatures that thrive in it. I have been inspired by the marine life that I had observed on television since a young age that allowed me to be fascinated by nature’s beauty and natural cycle of life and how everything it is the way it is, hence I would like to create a video that shows the wonders of nature and allow more people to acknowledge the beautiful nature around us.Diving is an activity that many individuals enjoy and appreciate.In order to make a connection with nature and be closer with it, I have
