| Facts: Icebergs are formed when large pieces of freshwater ice break off glaciers or ice-shelves. Usually only about 10 percent of an iceberg is above the waterline (leaving 90 percent of the iceberg below the water). The icebergs found in Newfoundland usually originate in Western Greenland from a large number of iceberg producing glaciers. Ocean currents move these masses of frozen water some 10 miles per day. An iceberg with a middle eroded down to or close to the water line and columns or pinnacles at either end is said to have a "drydock" shape. |
