All You Need To Know About Buoyancy and Polar Divers

Last week orchid class was visited by… a polar diver. He told us hundreds of facts about what it is like under the water, buoyancy, and what you need to do when you are diving.

Buoyancy

Buoyancy can be easy and difficult to learn but you will probably get it in the end. I found it hard to understand at the start but I got it in the end.

How to go down

When you go down there are tow different ways to do it. First, you will have seven weights and if you need more you will go down to the bottom of the sea and pick up a few rocks. Second, you will have air in your suit, so if you need to go down you press a button on the arm of the suit.

How to go up

When you go up there are also tow different ways to do it. First, you will have seven weights like you already know, you just need to take them of until you need to. Second, to go up you can let into the suit but pressing a button, it goes through a vowel and it goes into your suit.

About the divers

Simon Holebeach was the person was the person that came in and told us about everything you and I now know. To be a polar diver you need to pass a few tests to be able to be one. When you are a polar diver you have to help do a few things. First, they need to cut the ice into blocks and take them out using a strong rope. Next, they need to get their dry suit on; you can even where your clothes in it. After that, you can go under water and swim around. Every few minutes you have to tug on the rope to tell the person above water you are fine. Finally, you need to go up from the water really slowly because if you go fast when you get above water your arms and legs would hurt if you move them.

That is all you need to know about buoyancy and polar divers.
