    Underwater shark nets make us feel safer at the beach,but are we? That’s the question. Are we safe? There are lots of possibilities that the shark, with sharp like knife teeth, may outsmart us. Because of shark attacks we use nets, called shark nets. However, that doesn’t mean nets used in the past prevented shark attacks. These nets don’t only trap sharks they trap other sea creatures.

    Sharks have also been subjected to medical research, games and competitions, jewellery, souvenirs and cosmetics. We need to take into consideration that sharks play a vital role in the natural world that we live in. it is imperative that we look after these majestic creatures and ensure they remain protected. We need to be aware of the dangers of sharks, swim in protected areas where there are shark nets, and do not swim after dark in the sea (especially not alone) as the sea is the sharks home. Humans should also be wearing wet suits as protection in the ocean. The sea is where they live, they swim freely and they eat – they do not particularly target humans but rather prey on food that is available to them in their habitat.

    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

    To do a front dive a diver pushes his hips upward just slightly as he leaves the board. After he had begun to go up into the air, he throws his arms downward just enough to make is upper torso rotate around his hips. At the peak of the dive, the diver tightens his stomach muscles and pulls his legs up towards the sky, leaving his body in a perfect upside-down position to enter the water head-first.

  • Scuba Dive Essay

    835 Words  | 2 Pages

    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

  • Recreational vs. Technical Diving

    1425 Words  | 3 Pages

    In recreational scuba diving there is a laundry list of available equipment to fit nearly every underwater need. One of the most important pieces of equipment a recreational diver uses is the BCD or buoyancy control device. The BCD is an adjustable inflation vest worn by a diver to increase or decrease their buoyancy during a dive. The BCD is hooked to the regulator or “Octopus” which serves as a junction point for air accessories. The BCD usually comes complete with safety features like an emergency dump valve. Safety features like these help to prevent BCD malfunctions, such as runaway accents, by allowing the diver to release the air out of the vest. Attached to the regulator along with the BCD are air pressure gauges and two breathing apparatuses. One breathing apparatus is used for normal breathing function and the other is set in a known location in the case of an emergency or disorientation. Recreational divers also have a choice between wearing a neoprene wet suit, which keeps a diver warm by retaining a layer of water next to the body, or dry suits that use a layer of air for buoy...

    Try to be balanced on the board and paddle at almost the speed of the incoming wave. Raise your head when you paddle with arms bent at the elbow approximately ninety degrees. Reach out with one arm at a time, cupping your hands to make a scoop, stroking your way through the water. You don’t have to dig your arms too deep. Keep the movement of your arms nice and smooth, pulling the board through the water and finish your paddle by flicking your wrist as your arms moves past your hip.

    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.
