Crevasse Tracking

Crevasses are huge cracks that form on the surfaces of the ice sheets when stresses are high. They move with the ice and are convenient natural markers that can help us detect the movement of ice using Landsat imagery. Scientists have used these natural markers to help them learn how fast the ice moves, that the ice changes speed over time, and that the speed of the ice movement also varies a lot from one place to another.

Now you try!

You can try to track crevasses on your own using the RCO Applet. Try it now!
