For years, deep sea diving was primarily used for the research of marine organisms. Mechanics for scuba diving have improved greatly and became more available to the everyday thrill seekers. It has also become an interest to many people to learn and experience it as a recreational activity. Most of the people who dive without being certified or dive alone, face dangers that other trained divers are not subjected to. For example, diving alone is particularly dangerous as should an injury occur, nobody is there to assist. As for those who are trained and have companions, they may enjoy the experience of being surrounded by beautiful marine life and the earth’s natural wonders at less of a risk. Certified or uncertified there are still dangers that lurk beneath the water’s surface and accidents can occur at any time, anywhere. Safety precautions have been taken to help address the dangers that divers are at risk of while being submerged, but not all can be prevented and more still needs to be done. Being underwater is experiencing a whole new world. We don’t belong underwater so there are many things that have to be done to keep us safe. There are many hazards dealing with scuba equipment. Descending deep into the water is very tricky, as pressure increases, many things can go wrong such as decompression sickness. Decompression sickness is the result of breathing high pressure gases. Inadequate equipment for diving can lead to fatal injuries and illnesses, including nitrogen narcosis and oxygen toxicity. “The prolonged exposure to breathing gases at high partial pressure will result in increased amounts of non-metabolic gases, usually nitrogen and helium…” (Wikipedia #16) Nitrogen narcosis can affect a diver by giving them the feeli... ... middle of paper ... ...

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.
My vomit clouded the ocean surface with a purple-brown color before fading below the depths. On the other side of the vessel, I re-equipped my mask and plunged into the water to be greeted by my aunt – she was to be my snorkeling partner as she had much experience in the depths of Hawaii. When I submerged my head it was almost as if I had entered a new world. This unseen dimension housed a coral reef that vibrantly shone with a mixture of bright reds and deep blues. The reef almost seemed to pulsate as thousands of fish darted in and out of their subterranean homes. The water was thick with salt and teemed with plankton. We often resurfaced to point out fish to each other. I remember my aunt telling me of the environmental dangers of touching the still-living coral. “If you pierce its skin it will likely become infected and die, and all of the fish who live in it will die too,” she expertly explained. From then on I kept my distance to at least 5-6
Watching a movie where hundreds of swimmers on a beach are in a complete panic because of shark attacks makes a person scared to swim in an ocean, lake, or even a pond. Not only movies, but also documentaries of shark attacks stress how dangerous sharks are. In reality, are sharks really that dangerous or is it how they are portrayed? Stephen R. Palumbi who is a Professor of Biology at Stanford University and also the Director at the Hopkins Marine Station at Stanford wrote an article about other animals living in the ocean that are more dangerous to humans than sharks. In fact, he has written books about creatures in the water such as The Death and Life of Monterey Bay, and The Evolution Explosion. In addition, his son Anthony R. Palumbi is a novelist and a science writer that has written for Atlantic and other publications (Princeton University Press 1). Together they co- authored an article titled “Forget Shark Week: They aren’t the only fish in the sea” that was published the Los Angeles Times.

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.

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.
8. Do NOT use air-filled swimming aids (such as "water wings") in place of life jackets or life preservers with children. Using air-filled swimming aids can give parents and children a false sense of security, which may increase the risk of drowning. These air-filled aids are toys and are not designed to be personal flotation devices (life jackets). Air-filled plastic tubes can deflate because they become punctured or unplugged.
Many people think of scuba diving as just a swim in the water, but in reality it is a very exciting, dangerous, and potentially fatal sport and activity. There are many types of scuba diving, ranging from recreational to sport to career diving. Scuba Diving is just not a swim in the water, scuba requires certification, uses technical equipment, and there is a lot of risk involved with scuba diving.
We have all been underwater at some point in life whether it was in a pool, lake, or in the ocean, but that was probably for a short amount of time. With Scuba Diving, you get the opportunity to be underwater for more than 10 minutes at a time without having to worry about things on the surface. With Scuba Diving already having been banned temporarily a while ago in Crater Lake because of concern about the environmental impacts of invasive species to the marine ecosystems, some people think that Scuba Diving could become banned in more places, if nothing is done to combat the problem. Today, I will discuss Scuba Diving and its effect on the environment along with how to make it safer for the environment. During this past year, I learned to scuba dive and was certified for Scuba Diving at Neptune Dive and Ski. Today, I will discuss the effect of Scuba Diving on the environment through my research, product, and learning stretch. The first task that I was faced with was gathering information about Scuba Diving and researching the problem and the multiple ways to resolve the problem that it has on the environment. I researched the problem and ways to resolve the problem that Scuba Diving has on the environment, with my thesis focusing on how Scuba Diving although damaging to marine life and plants, could with the proper training be one of the best helpers of the present and for the future of the ocean life. Scuba Divers go into some of the nicest bodies of water in the world with the intent to observe and interact with the environment that is beneath the water. However, some Scuba Divers lack the proper training and knowledge necessary to dive in the water safely and carefully. Scuba Diving is meant for recreational use and for educat...
The lorenzini is a pit-like organ located on the head of the whale shark that senses weak electrical and magnetic fields. This is an area that is currently being researched extensively and is largely unknown. It is speculated that this organ is used by the whale shark as a navigational aid by using the earth’s magnetic force (Rowat 2012). Evolution Studying the evolutionary history and adaption for this species is difficult and an ongoing struggle for scientists. It is classified in the order of Chondrichthyes, suborder Elasmobranchii, and family Rhincodontidea.
