Studying Ice Flows for Clues to Climate Change

What's better than watching ice melt? Building a computer model to simulate the melting! Ice flow plays an important role in everything from deep ocean circulation patterns to global warming.

Maps

Why are there over 100 types of map projections? Because translating a globe onto a flat surface usually requires some compromise—cartographers must distort some features in order to preserve others.

Mercator Projection

A globe may be the most accurate way to represent the Earth, but you can't slip one into your back pocket. The Mercator projection map is certainly portable, but look what it does to Antarctica!

Polar Projection

If you've ever compared a map of the world and a globe, then you've seen how Antarctica can get really distorted. See how a polar projection map solves that problem.

Which Map's the Best Map?

As a miniature model of the Earth, a globe is the most accurate representation of our planet. Yet it's not what most scientists use to do their work. What do they use instead, and why?

Making Map Projections

Don't toss that empty soda bottle! Grab a knife and test out your cartography skills. You'll never look at a map of the Earth in the same way again.
