James Cameron, director of Titanic, Avatar, and many other famous movies once said, “Every time you dive, you hope you'll see something new - some new species. Sometimes the ocean gives you a gift, sometimes it doesn't.” As you are swimming under the ocean, imagine the sparkle of the water as you look up the surface from a hundred feet below; floating along with the current, slowly and deeply breathing while observing the sea life. Continue to imagine the ability to remain underwater for an hour or more, just swimming and observing the ocean. This is the life of a scuba diver. Many people think of Scuba Diving as a swim in the water, but in reality it is a very dangerous, and potentially fatal sport and activity. There are many types of Scuba …show more content…
Diving, from recreational to sport to career diving. Scuba requires a certification, uses technical equipment, and a lot of risky situations. To begin with, Scuba Diving is the sport or pastime of swimming underwater using scuba gear. In order to safely dive the divers need many different types of equipment. This includes the BCD, mask and snorkel, fins, weight system, regulator, scuba tank, etc. All this equipment is vital to dive because they are what the diver’s life relies on while underwater. As for what this equipment does, it’s quite simple. The BCD is the buoyancy control device. It helps the diver to sink to the bottom or (when inflated) slowly rise to the top. The BCD also has many pockets and buckles to hold down other gear. The mask and snorkel are worn on the diver’s face. The mask allows the diver to see and the snorkel is used before submerging underwater so they oxygen isn’t used up from the tank. According to Lloyd Lee, author of Scuba Related Facts You Probably Didn’t Know, masks also help to protect eyes from the sunlight reflected off the water or else the diver would not be able to see. Fins are also essential. If the diver wants to efficiently use their time underwater they must wear fins to help propel them and steer them in the water. In addition, fins protect the diver’s feet from the coral and other living things in the ocean. Another necessary item is the weight system. Naturally, the human body is buoyant, therefore in order for the diver to sink to the bottom weights must be worn around their waist to guide them down. With the help of the BCD as well the weights the diver will find the proper amount of flotation to help move around the bottom comfortably. Lastly, there are the scuba tanks and regulators. These are the most important of them all because they are what supply the oxygen when diving. The scuba tank is worn on the diver's back with the regulator screwed to the top. The regulator along with an extra emergency regulator, are strung through part of the BCD to have easy access if needed. Quite clearly, all these items are indispensable if someone wanted to go Scuba Diving because they all play a large role in the diver's safety. Moreover, there are many difficulties in Scuba Diving that may not be very apparent to those who do not dive.
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
safe. To conclude, Scuba Diving has come a long way from the old historic ways to become a modern sport and recreational activity. Scuba Diving requires technical equipment along with a knowledge the dangers that can occur while underwater. Scuba Diving is not a swim in the ocean, but it is a very enjoyable even though it can be potentially fatal. Next time you and your family take a trip to a tropical location, be sure to try Scuba Diving.
Deep water and strong currents could lead to drowning. - stay away from the sea.
Decompression sickness is unusual in diving mammals, but may occur under specific circumstances, including an uncharacteristically rapid ascent to the surface. Rapid ascents such as these may be the result of predation, stress, or even due to sonar signals from sources such as military operations. Marine mammals such as beaked whales have been found stranded on coasts with gas bubble associated lesions on vessels and in vital organs. This is thought to be the result of intense sound that may destabilize the gas nuclei, leading to nitrogen bubble growth in tissues that have been supersaturated during a dive (Jepson et al., 2003). Decompression sickness due to sonar from naval and military operations seems to arise from repetitive shallow dives instead of long, deep dives, facilitating higher tissue supersaturation levels (Tyack et al., 2006).
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.
Fly fishing. A sport that many enjoy and many more think is a simple task to do. Those many people have a surprise coming their way. There are many movements, and techniques that are involved in fly fishing that make it more fun, and easier to participate in.
There is no all-embracing definition of what is known as intense kayaking. This is because every definition will be on the experiences experienced by every kayaker. However, a closer look at intense kayaking will reveal that intense kayaking is generally considered by those kayakers who find a lot of fun kayaking is bustling waters. Keep in mind that intense kayaking will also warrant the need of very special kayaking skills.
“Skeletons don’t like to stay in closets,” Clare states in the first pages of Learning Not to Drown, a novel by Anna Sindoa. The protagonist of the novel, Clare, and has plenty of skeletons in her closet, but one in particular stands out from the crowd. Luke, her older brother, just got released from prison for the 3rd time and even though she doesn’t show it, her fear is unimaginable. Anna Shindoa uses a non-linear plot line with narrating shifts and abrupt transitions to provide additional perspectives to the story this structure highlights the twists and turns that ultimately lead to the conclusion that for one to move on with life, they first have to accept their past.
Before engaging in the sport of scuba diving, individuals must undergo a training process that ends in official certification from a qualified agency. For most recreational divers, this means completing all three stages of the Professional Association of Diving Instructors (PADI) Open Water Diver course.
I am writing this essay about ‘shark finning’. What is it and why is it done? Shark finning is when the shark is captured and the fins are cut off to sell. The shark fins are used in medicines in China but are also used as a decoration in shark fin soup. There are many problems due to only the fins being taken. Firstly the sharks are thrown back into the ocean still alive, without their fins they are not able to swim causing them to drown. The Second problem is that the shark fin has no nutritional value in the soup and is there for no good reason, the only reason they are used in the soup is because the Chinese see them as a delicacy. These are both very good reasons why sharks shouldn’t be hunted and killed for their fins; however, it still happens on such a massive scale.
For example, the effects of long term diving can be described by interviewing retired divers, reviewing medical records or research studies.
An event in my life that is memorable would be when my Uncle Bob and I decided to go scuba diving. In our adventure, Uncle Bob was bitten by a five-foot bull shark and later at 70ft below sea level he ran out of air. These events have taught me that scuba diving can be a dangerous activity, that I must be aware of my surroundings, to refresh my scuba training and to remember safety techniques.
To me the term dive deep means to keep going on as far as possible. Obstacles will come crashing your path toward success, but you have to keep moving forward. When I was in high school, I joined track and dance. Every day I had difficult tasks to perform. Whether it’s to do pirouettes (an act of spinning on one foot) or running three miles in the rain, I managed to keep pushing myself. Even when I was injured, I kept pushing myself. My coach would always tell us “pain makes you stronger” and it sure
Sky diving is usually something a person always wanted to do. Especially the idea of trying new things. That’s what I did over the summer, did something new. Leaving a country can be scary especially for the first time.
I wouldn’t be who I am today without: Swimming. Swimming has allowed me the opportunity to travel the world. There are not many eighteen year olds that could say they have traveled Puerto Rico, Missouri, Minnesota, and California. I was lucky enough to be able to travel around the world to compete at different competitions. Swimming gave me the opportunity to pursue my dream of competing at the Division One level. At Colgate University, I was training at the highest level, learning a lot about myself as I was constantly being pushed to my limits. I met many of my lifelong friends though swimming in high school, on my club team, and in college. My swimming career has allowed me the opportunity to coach both on the high school level and collegiate
My family is from Plainfield, New Jersey. During the summer we would frequent the public pools in our community. For as long as I could remember I have always loved the water. As a child, I would often jump in the water with no resistance or fear, and would have to be rescued by a family member. These near drowning experiences never place fear into my heart because I would immediately return to the water. In middle school, I decided to join the swim team. After all the years I spent jumping in the pool with no inhibitions, I had never learned how to swim. I spent a good portion of the swim season learning the basics: breathing under water, breathing techniques, kicking and proper stroking. By mid season my coaches were confident enough in my swimming abilities for me to swim in the 25 meter races. And by this time I recognized swimming lack it’s original zing, as an organized sport. By ninth grade I
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
