How To Snorkel Jonathan Bryant

  1. 1. How To Snorkel By Jonathan Bryant
  2. 2. What is Snorkeling? <ul><li>Snorkeling is a water activity in which your face is underwater, and you are wearing a snorkel, mask, and flippers. </li></ul><ul><li>The snorkel is a long tube that allows you to breathe while your face is underwater. </li></ul><ul><li>It is also referred to as skin diving. </li></ul>
  3. 3. What is Snorkeling <ul><li>Many people enjoy snorkeling because it is an easier alternative to scuba diving. </li></ul><ul><li>People who snorkel don’t need to wear the air tanks that are needed for scuba diving. </li></ul><ul><li>In snorkeling, you don’t have to raise your head because the snorkel allows you to breathe. </li></ul>
  4. 4. The History of Snorkeling <ul><li>Before the snorkel was invented, people had been free-diving for centuries. </li></ul><ul><li>In Korea and Japan, female divers called Ama divers would collect shells and seaweed. </li></ul><ul><li>In the Mediterranean, people would dive to collect sponges at the bottom of the sea. </li></ul>
  5. 5. The History of Snorkeling <ul><li>Alexander the great was fascinated with underwater life. He would observe fish in what he called “the glass barrel”. It was simply a glass cylinder that he could fit inside of while he was lowered from a boat. </li></ul>
  6. 7. The History of Snorkeling <ul><li>Leonardo Da Vinci experimented with an early air tank. His air tank was only a bag full of air. </li></ul>
  7. 8. The History of Snorkeling <ul><li>In the 20 th century, more advancements were made in the field of underwater diving. For example: </li></ul><ul><li>The armored suit was created in 1932. </li></ul><ul><li>Flippers were patented in 1933 by Louis de Corlieu. </li></ul><ul><li>The aqualung was used in 1943. </li></ul>
  8. 9. Snorkeling Equipment <ul><li>The three essential pieces of equipment are the mask, snorkel, and fins. </li></ul><ul><li>If you are in cold water, you can wear a wetsuit. A wetsuit helps to you to keep warm. </li></ul><ul><li>Some people who snorkel wear a weighted belt which helps them to descend quickly when diving down. </li></ul>
  9. 10. Equipment: The Snorkel <ul><li>Snorkels are not new devices. Breathing tubes have been used for 2,000 years. </li></ul><ul><li>There are two types of snorkels, one for scuba diving and one for snorkeling. </li></ul><ul><li>The snorkel is always worn on the left side. </li></ul><ul><li>It is connected to the mask with a piece of rubber. </li></ul><ul><li>Snorkels should not be longer than 17 inches. </li></ul><ul><li>Some snorkels have a self drainer to filter water. </li></ul>
  10. 12. Equipment: The Mask <ul><li>The mask goes over the face to cover the eyes and nose, with a strap attached to the back of the head. </li></ul><ul><li>Snorkeling masks are made of silicon. This helps them not to rot in the sun. </li></ul><ul><li>You can tighten your snorkeling mask with the strap. </li></ul><ul><li>Inside your mask, an air pocket is created to help you see without water filling up the mask. </li></ul>
  11. 14. Equipment: The Flippers <ul><li>Novice snorkelers often mistake them as fins, but the correct term is flippers. </li></ul><ul><li>They slide over the feet and help to propel you smoothly, and efficiently. </li></ul><ul><li>Fins have two parts, the pocket, where your feet go, and the blade, which is the tip. </li></ul>
  12. 16. Method <ul><li>In snorkeling, you can make a free dive downwards by bending your waist and kicking your legs upward. This will weigh you down so you can dive. </li></ul><ul><li>When you dive, your snorkel will fill up with water. This means you must blow the water out when you reach the surface by “blasting” or “popping”. </li></ul>
  13. 17. Method <ul><li>When diving, you will feel water pressure in your sinuses. </li></ul><ul><li>To relieve the pressure, hold your nose and blow out. </li></ul>
  14. 18. Method <ul><li>Blasting and popping refer to blowing air out so the water leaves the snorkel. </li></ul><ul><li>Another method of filtering water out is through displacement. </li></ul><ul><li>In displacement, the diver tilts his or her head back while coming to the surface. As they reach the surface, the water flows out of the tube while the snorkel is tilted downward. Displacement is much easier than blasting. </li></ul>
  15. 19. Safety and Environment <ul><li>There are several dangers a swimmer should be aware of while snorkeling: </li></ul><ul><li>One of the largest risks when snorkeling is called shallow water blackout. It occurs when a swimmer loses breath after exhaling too much. This causes hypoxia, which is the depletion of oxygen. </li></ul>
  16. 20. Safety and Environment <ul><li>Another danger people face is their environment: jellyfish, boats, and sea lice are just a few of the many hazards that might be faced. </li></ul><ul><li>Fatigue can also be a risk for safe snorkeling. </li></ul><ul><li>To stay safe, snorkeling should be done in pairs to help avoid any risks. </li></ul>
