Detailed Description
Figure 3: Digital Elevation Models (DEMs) quantify the size and shape of a glacier at a specific time. Two DEMs can be compared to estimate glacier volume change over the interval between DEM acquisitions. This image shows elevation differences (meters) across Gulkana Glacier, Alaska, over a 5 year interval (2010-2014). The difference documents rapid thinning near the glacier terminus and thinning over most of the glacier, with thickening only in the uppermost reaches.
