[ACC39-P02] Glacier flow velocity changes near the border of Alaska-Yukon detected by the Sentinel-1B SAR images
The spatial and temporal velocity changes of mountain glaciers near the border of Alaska-Yukon from 2006 to 2011 were investigated using ALOS / PALSAR data (Abe and Furuya, 2015). Abe and Furuya (2015) reported that, at many of the quiescent surge-type glaciers around the St. Elias Mountains, upstream accelerations occurred from autumn to winter and then propagated towards downstream.
In this study, we applied offset tracking to Sentinel-1B / C-band SAR data on glaciers near the border of Alaska-Yukon to examine their spatial and temporal velocity changes. As a result, we have confirmed winter acceleration on the Anderson, Chitina and Klutlan glaciers, which is consistent with the finding by Abe and Furuya (2015).
