You’ve just learned how to measure the size of tabular icebergs using satellite images. Here are some important things you should have learned:

• Tabular icebergs can be big. A single iceberg can comprise an area the size of a lake or a city.
• The geometric shape method can be used almost anytime to obtain a quick and rough measure of an iceberg’s area.
• The pixel count method provides a quick and precise area measurement but requires using special software.

The links in the side bar will take you to web sites where you can obtain up-to-date satellite images of icebergs. Here are some things to remember as you try out your new skills.

• You need to know the proper scale of distance associated with any particular iceberg satellite image.
• If you download the Pixel Count tool be sure you know the resolution of any imagery used with it.
• Greenland is another area with a lot of interesting recent iceberg activity.
