Now we are ready to start.
INTERVIEWER: Our program about extreme sports is on and today we’re going to learn about scuba diving. Our expert is Barbara Green who owns a diving school.
BARBARA: Hello, everybody!
INTERVIEWER: Barbara, what’s the difference between diving and scuba diving?
BARBARA: The word scuba stands for a self contained underwater breathing apparatus. That’s the basic difference. Knowing how to scuba dive opens up an entire underwater world of coral, fish and other creatures. You can even say “hello” to a shark. That’s a joke though.
INTERVIEWER: People say once you’ve tried scuba diving, you’ll never forget it. Is that true?
BARBARA: Imaging swimming in clear blue waters. As you look at brightly colored fish and striking shapes of coral organisms. The underwater word is quiet except for the sound of your breathing. Can you ever forget it? Would you like to go back and see it again?
INTERVIEWER: I guess that’s the answer to my question. I hear scuba diving needs a lot of stuff and can be expensive.
BARBARA: Scuba diving requires several pieces of important equipment which can be relatively expensive. Scuba divers must wear a mask in order to see underwater. The mask creates an airspace that protects the eyes and nose. Divers wear scuba fins on their feet. Without them it’s impossible to move easily and quickly through the water. Many divers also wear a wetsuit to stay warm underwater.
INTERVIEWER: Is scuba diving dangerous?
BARBARA: Basically, no. But the ocean demands respect. Divers wear a BCD or Buoyancy Control Device to control how much they float or sink, a pressure gauged device tells divers how much air is left in the air tank or a dive computer can calculate how much air is left as well as a diver’s depth and the length of time they can stay underwater. Scuba divers breath with a regulator which brings air to the mouth when they inhale. The regulator is attached to an air tank that is placed on a diver’s back. There is also an extra regulator called an octopus. It’s used in case of emergency situations.
INTERVIEWER: I know decompression sickness is a great problem for divers.
BARBARA: You are right. It is a major concern for divers. The deeper a diver goes, the more pressure the surrounding water puts on the volume of the air inside his or her lung. And the deeper a dive, the more nitrogen gas goes into the diver’s blood.
INTERVIEWER: Do you teach it in our school?
BARBARA: Of course. To learn how to use all this equipment it helps to go to dive school. Becoming a certified diver requires three series of lessons. New divers must learn about the physics and safety of diving and practice diving skills first in a closed water area and then an actual beginner dives. Several organizations offer official diving certifications.
INTERVIEWER: Do people dive alone apart from the instructor?
BARBARA: Another important aspect to diving is having a “body” system. Having a diving partner you can watch over one another and help if there’s an accident.
INTERVIEWER: Any final comment from you?
BARBARA: One important diving rule is to never touch any of the sea life. This rule is to protect both the diver and the underwater environment. For example, there’s a reason fire coral received its name, it cause a painful burning feeling if touched. A diver could also be cut by touching a sharp piece of coral. It may seem hard like stone but it’s actually a very fragile organism. It can be damaged if divers touch or stand on it. To protect the beautiful coral reefs divers must treat them with care. Sorry to say, tourists often forget about this.
