A new video has been released by the National Park Service highlighting the work being done to document and monitor the effects of melting permafrost.  Terrestrial Ecologist Dave Swanson describes how ice melting below the surface of the tundra progresses into a thaw slump and how 3-dimensional modeling provides a means of measuring this change over time.  Click on the image below for a link to YouTube.
