Glacier mass and area changes on the Kenai Peninsula, Alaska, 1986-2016

Glacier mass loss in Alaska has strong regional and global impact on climate and sea level rise, however, accurate assessment of regional mass balance is challenging for lacking of continuous and long-term in-situ measurements. Here we mapped glaciers in Kenai Peninsula in the four different date, 1986, 1995, 2005, 2016, and presented a time series of area changes using Landsat images complemented by Sentinel-2 and ASTER images. Changes in surface elevation and volume of Kenai glaciers were determined by differencing digital elevation models (DEM) from ASTER stereo images in 2005/07 and Interferometric Synthetic Aperture Radar (IFSAR) DEM in 2014.
