Using Landsat to Study Permafrost

Using NASA's Landsat satellites, scientists have been able to assess how Earth's surface has changed from 1972 to the present. One example of how Landsat was used to study a "landscape of thawing permafrost" that resulted in coastal erosion and lake evolution in Cape Halkett, Alaska from 1955-2005 is described here and in a two-page pdf with accompanying satellite image. Additional Landsat images of the region can be found here.
