The Dangers Of Scuba Diving

How is it possible for scuba divers to stay underwater for a long period of time? A man named Jacques Cousteau made that all possible. His invention of the aqualung made scuba diving possible, letting people explore the underwater world.

A diver descending to a depth of 10 meters, is equivalent to the entire 150km of atmospheric air (1 ATA). This is due to water being much denser than air. If the diver were to descend another 10 meters, the water will exert a further pressure, equal to another atmosphere, 2 ATA.

Imagine a place where you can see your favorite sea animals. Whales, dolphins, sharks, even penguins. Doesn’t that sound like somewhere you would enjoy going? SeaWorld is what comes to most people’s minds when they think of this, but is SeaWorld really that wonderful? Is SeaWorld truly what it’s hyped up to be? SeaWorld claims to be a sanctuary for animals where they keep animals like killer whales safe from the dangers of the world. Well, SeaWorld should really get a dictionary because a “sanctuary” is truly not what they give these animals. Orcas are the main attraction of SeaWorld but they are also one of the animals that suffer the most. Orcas in SeaWorld lifelessly float in their pool with little to no shade from the sun. In the wild,

First of all, ocean exploration technology has advanced much more than before in the past decade. In the past, people had to bring everything needed for scuba diving which included hundreds of pounds of gear and photographing technology. Now, all

Diving up a mountain can be quite frustrating especially when getting to certain altitudes the ears start to pop. It is the

Conveying a human to a different atmosphere inflicts barotrauma which is the inability to equalise pressure within the body cavities. Boyle’s law explains as pressure increases on our bodies the volume of our body cavities decrease and as pressure decreases the volume is increased. A changing pressure between a gas space in our bodies causes physical damage to tissue. Astronauts experience this from the change in pressure between their space suits and the shuttle. However, divers are subjected to greater changes in pressure the deeper beneath sea level resulting in more harmful

I lost hearing in my left ear, probably due to the air

They call the "finders keepers" concept and stipulates that since they found the artifact they should be the rightful owner of those objects. When you dive, the underwater pressure squeezes your internal organs in an unnatural way that many divers claim to be the holder since they put their heath at risk when they fetch the treasures. This is not an act of bravery but one blinded a quest for money and

Based on the information given to us, diving was the most difficult, challenging, and frustrated task. There was only one encounter and that was during Hurricane Andrew. Hurricane Andrew kept the Gulf of Mexico going. It had more oil and gas than they thought and it was a mixture of saltwater and freshwater. The sharks were addicted to the shiny tools hanging down from the equipment. They had helmet cameras and the people watching from the surface would mess with them about it. The shark didn’t bite, it just went for the gut and felt as if it was punching

Surfer's ear occurs because surfers experience both cold wind and water exposure while they're out on the waves. The bone surrounding the ear

Adventure diving generates a higher margin and therefore it is a good idea for Greywell to consider adding it to the mix of dive offerings. However, it cannot be considered without weighing the risks involved. Coral Divers Resort has an excellent reputation and careful consideration should be given as to how to protect this intangible asset. Adventure dives would need specifically trained and experienced dive masters. Simply training existing employees might pose an additional risk since they aren’t too excited about diving with sharks and also lack experience that might be helpful for safety issues.

In “Through the Tunnel,” Doris Lessing presents water as a deadly challenge to the boy, Jerry. He experiences two of the listed symptoms after freediving; “That night, his nose bleed badly. For hours he had been underwater, learning to hold his breath, and now he felt weak and dizzy” (Lessing 405) and “... his face turned up to the air. He was gasping like a fish. He felt he would sink now and drown; he could not swim the few feet back to the rock” (Lessing 407). Water challenges him on his quest to adulthood and Jerry then experiences rebirth as a man; water is symbolizing

The presence of a dive response in humans when the face is submerged in water was studied. A lot of mammals have shown to exhibit a dive response known as the mammalian dive reflex. During this reflex bradycardia, a slowing of the heart rate, is shown. In this study, human subjects were put through various tests to determine if humans also exhibit bradycardia. Subject's heart rates were measured while breathing normally, while holding breath and while holding breath with face submerged in water. The results showed that there was a significant decrease in heart rate while submerged in water as compared to normal breathing or holding breath out of water. Many other studies have been done that agree with the results found in

As a teenager, my passion for marine biology ran rampant in all parts of my life. I went as far as becoming a certified open water diver to further understand what lay in the depths of the water. However, obtaining the certification wasn’t as simple as putting on a diver’s suit. Gliding through the water, scuba divers make the sport look effortless, however there is a sense of strength, dexterity, and health that is required to be successful. As enthusiastic as I was to gear up in scuba-wear, I was just as afraid as I descended into the cold environment. My body was getting colder and colder. I could feel nothing but

But almost everyone at least experiences the sense of breathing in water from a pool or other water locations. It’s a feeling like no other, where, you know you need to get to the surface and breath oxygen and cough the water out of your lungs, but for those who are seriously drowning it’s another story. They have no where to go and their chest is convulsing until the pain just subsides and it becomes almost a pleasant feeling as they fade into the blackness of their subconscious where they soon die within minutes. For most people in those experiences people always think you have to go for life, but you don’t. You can
