Zoom in on sea ice

Time for some adventure! We're going to take an exciting journey through the sea ice. We'll start by flying 20,000 m up in the air. As you zoom in closer and closer, we'll come crashing down to the surface of the ice. We won't stop there, though; you'll even get to go inside the ice. Usually, only scientists with high-tech equipment get to see the ice this closely. To continue your adventure, read the caption and then choose your destination.

This picture is 100 m (or 0.1 km) across. This is the way sea ice would look if you were in an airplane looking down from an altitude of 200 m. Do you see the melt ponds? Notice that the melt ponds on the ice are many different shades of blue. The colors are determined by ice that is underneath the water in a melt pond.
