Scuba diving is the kind of diving that one uses a breathing apparatus under water, which acts as a gas supplier to the diver. It allows divers to stay under water longer than with breath-holding methods. While diving, one uses swim fins attached to the feet. Scuba diving is carried out for both recreational and professional reasons among them cave diving, wreck diving, ice diving and deep diving for recreation purposes. Professional diving is done by those at civil engineering department, naval diving and rescue reasons. I began as an open water diver, now am a rescue diver and hoping to master in diving (Robinson, page 2). The Red Sea lies between arid, semi-arid and desert land, it has great depths and efficient water circulation patterns. The Red sea is a perfect place for diving; here there are many places to dive. In particular Dahab which is very beautiful with mountains, the smell of the sea and sand. Dahab also enjoys pleasant weather all round the year and experiences a vast number of tourists. Popular activities around this place include snorkeling, wind surfing and scuba diving. Land activities around Dahab are; jeep rides, camel trips and drive to Mount Sinai. I mainly practice my professionalism in this region (Printfu). While I was an open water diver, I did diving for recreational reasons. I had obtained my technical training and was certified as a diver. I progressed with thorough training, gained experience, and advanced my techniques to become a rescue diver. During then, I did wreck diving, where I explored shipwrecks. Shipwrecks are attractive to divers as they act as habitant to marine life and provide challenge to their skills. Diving in a shipwreck through the narrow passages one must navigate, and the ... ... middle of paper ... ... in better communication with their partners. Another requirement of diving is mobility in water. Swift movements in deep waters will make it enjoyable for a diver to have a great distance to cover as compared to less mobile divers. It is therefore important a diver to be trained to meet the desired level of diving capability (Ferrer, page 8).

Deep water and strong currents could lead to drowning. - stay away from the sea.
In the Thunder Bay area, the collection of shipwrecks reflects the transitions in ship architecture and construction throughout history. From wooden schooners to early steel-hulled steamers, as well as several unusual vessel types. The Great Lakes actually have some of the best shipwreck diving locations in the United States for two primary reasons. The wrecks found here generally maintain their structural integrity longer than salt water ocean wrecks.
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.

This force now can be used by the diver not only to go up, but to rotate and therefore perform various dives.
Archaeology is a continuously evolving field where there is a constant stream of new branches and excavation methods. Due to the influx of new technologies and innovations in recent decades, archaeologists have been able to excavate previously inaccessible areas. For example, new diving equipment and tools such as proton magnetometers, side-scan sonar, sub-bottom profiler, and miniature submarines have allowed archaeologists to dive into the deep depths of the ocean. As a result, the branch of underwater archaeology was created to search for shipwrecks and other artifacts on the ocean floor. Underwater archaeology’s role has increased in recent years as it allows archaeologists to more accurately interpret the past by supplementing information gained through traditional land excavations.

Divers cannot put the equipment on and immediately dive in. Before diving there are a series of procedures the diver and their partners must do before going down. In addition, the further down the diver dives the more pressure pressing down on the diver which lessens the amount of oxygen in the scuba tank. Therefore, the further down the diver dives the less time the diver can spend on the bottom. 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. Also, when diving the diver must take into account the amount of time spent descending and ascending in the water. If the diver descends too quickly the pressure can deflate their lungs and cause problems. Similarly, if they ascend too quickly nitrogen bubbles can form under the diver’s skin causing bends or decompression sickness. This sickness can be extremely harmful and possibly fatal. Lastly, a dive watch or computer is needed to calculate the amount of oxygen left in their tank and the depth. Dive computers help the divers be aware of their conditions and keep them
Surfing is the sport of riding a surfboard toward the shore on the crest of a wave. It is an amazing sport to learn and it gives the rider a hell of an adrenaline rush!! There are three major phases of surfing – paddling, push up and the standing position. This report will give you a full understanding of the correct techniques to use while surfing and it also describes the basic structure and function of the muscular-skeletal and cardio-respiratory systems of the human body. It will also describe the many different energy systems and how they change when surfing.
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.
Before recreational or sport divers can take a plunge into the water, they must complete a course in scuba diving and become certified. There are many scuba diving agencies, the largest being PADI, but there are many others, including the National Association of Underwater Instructors and the National Association of Scuba Diving Schools. All agencies require that participants be proficient swimmers, in reasonably good health, and at least 12 years of age. The course usually consists of classroom work, practice in a pool or confined body of water, and dives in open water. In the course, students learn to use diving equipment, to equalize air pressure as they descend, to swim efficiently underwater, to clear the mask if water leaks in, and to ascend safely. Because divers cannot talk to each other underwater, they also learn how to communicate underwater with hand signals. Scuba diving should always be practiced with at least one other person, and partners should remain together throughout the dive. Certification courses teach divers the rules and advantages of the buddy system. Diving partners learn to double-check each other’s equipment, share a single air supply, and assist one another should a problem occur. Neutral Buoyancy is an important skill taught in certification class. Neutral Buoyancy is a state, in which the individual neither sinks nor floats. In this weightless state, a diver conserves energy and air and keeps diving equipment off the bottom where it could be damaged.
The affects of swimming on disabled people’s bodies’ physically is colossal due to the fact that water provides support, stability, and has numerous healing mechanisms. According to aquatic therapist Stacy Bintzler, “Water has four main features that are not offered through land activity: buoyancy, resistance, support and hydrostatic pressure” which allows for simple movement to be less painful and easier in comparison to the same movements on land (Bintzler). Water’s main components aid in the following ways: buoyancy, reduces stress on joints; resistance, buil...

To have a good career you would have to have gone to college somewhat and know what you’re talking about. Ashley Simmons says “Classes in college are really just core classes like English, history, biology, etc. Although for aquatic biology you need to take biology because without it, it would be pointless. Some classes are essential like math, science, engineering, and physics” (Simmons). The requirements in studying to be an aquatic biologist are very simple. There are not too many, but obviously you do need some requirements because you need experience and you have to have standards. Diving is one of these requirements. “In studying to be an aquatic biologist you have to actually get in the water so lots of dives are required. Most are freshwater, but some may be saltwater just for overall experience.” (Simmons)...
