Ice: a closer look


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 0.00001 m (0.01 mm) across. This photograph was taken using a special kind of microscope called an electron microscope.  It works by hitting the ice with very small particles called electrons. We are now inside a brine pocket looking at the very tiny salt crystals that form.
