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…
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
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.
“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.
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.
Diving has gotten away from the stereotype based on the early days of diving, that it is a rough and tough sport requiring extreme endurance and strength. Today it is viewed as an activity done by both men and women and even children. While diving is promoted as a leisure sport, it is still a sport. One that takes an amount of physical activity. We start by carrying heavy tanks on our backs. We are in constant motion for the entire dive. Even breathing is a more difficult as we must overcome the additional pressure on our body as we expand our chest.
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.
There are an estimated 8,000 deaths per year in the United States from drowning. Near-drowning occurs anywhere from 2-20 times more frequently (for estimated 16,000-160,000 events per year)7. The definitions for drowning and near-drowning have for the longest time been very confusing to understand. Recent health officials have attempted to resolve some of this confusion by redefining drowning as “the process of experiencing respiratory insufficiency or difficulty following a submersion or immersion in a body of liquid.” Near-drowning has also been redefined as “survival from a drowning event which involved impaired consciousness or water inhalation for 24 hours or more”2. Both near drowning and near-drowning occur when someone experiences a submersion event. A submersion event is when someone, in this case a pediatric patient, experiences an unexpected submersion in water. When an unexpected submersion, regardless of water type (salt or fresh) occurs, the individual experiences breath hold, panic, and a struggle to resurface1. Humans, naturally, can only hold their breath for a short period of time. This prolonged breath hold results in hypoxia and eventually leads to involuntary gasping. As the individual attempts to gasp for air they sometimes aspirate7. This paper will attempt to look at the clinical presentation of a near-drowning patient who has suffered from a submersion event.
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.
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.
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
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
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)
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
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.
