  Icebergs                                                                                               Go back one page  

Mr. Okpik takes you on his snowmobile and together you travel to the nearby Frobisher Bay. On your way you encounter many different glaciers, but they're moving so slow that they appear to be still. As you approach the bay, Mr. Okpik points to a glacier that managed to make it all the way into the water! Suddenly you see a huge chunk of ice snap off the top of the glacier, crashing with a loud bang as it hits the water.
 

"That is how icebergs are created. When a glacier is able to reach the sea, it makes an 'ice shelf', a large piece of ice connected to the glacier that floats on the water. During a process called 'calving', parts of the ice shelf snap and break off like you just saw, forming freely floating icebergs. The way it floats in the water makes it so that you can only see the tip of the iceberg. In fact, nearly 90% of the iceberg remains underwater. This is why it's very dangerous for ships to be traveling in iceberg territory, because without proper technology they can't see the ice that lies beneath!"
