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 10 m across. The photograph was taken by a person standing on the surface of the ice. It shows two researchers taking measurements on Arctic sea ice in July. The ice has melted so much it is a good idea to wear a life jacket, in case you fall in!
