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

Several studies reported glaciers on the Kenai Peninsula in Alaska have experienced widespread recession since the Little Ice Age Maximum. However, most studies have been carried out on parts of the whole glacierized region. In this study, we estimate the glacier volume and mass change by geodetic method, derived from derived from DEMs generated from ASTER images in 2005 and the IFSAR DEM in 2014, to reveal substantial thinning and mass loss between 2005 and 2014. The ASTER data were acquired between 9 August and 14 August 2005, while the IFSAR data were acquired between 29 August and 12 September 2014.
