Icebergs
This site contains both qualitative and quantitative information about icebergs. Students will discover that an iceberg is a massive piece of ice of greatly varying shape, protruding 5 m or more above sea-level, which has broken away from a glacier and which may be afloat or aground. They will also find that icebergs are classified by shape and size. This information is from the Manual of Standard Procedures for Observing and Reporting Ice Conditions. It describes the shapes as tabular, non-tabular, domed, pinnacle, wedge, drydock, and blocky and supplements the description with diagrams. Size is classified on the basis of height, length and weight and includes growlers, bergy bits, and small, medium, large, and very large bergs. Students learn that bergs are mainly white but may appear blue if bubble free and may also be dark from wind blown debris. This site also contains information on the migration and movement of icebergs, including a migration chart.
