Global Land Survey (GLS) data encompassing Landsat Multispectral Scanner (MSS), Landsat 5?s Thematic Mapper (TM), and Landsat 7?s Enhanced Thematic Mapper Plus (ETM+) were used to determine the terminus locations of Baird, Patterson, LeConte, and Shakes Glaciers in Alaska in the time period 1975-2010. The sequences of the terminuses locations were investigated to determine the movement rates of these glaciers with respect to specific physical and environmental conditions. ? GLS data from 1975, 1990, 2000, 2005, and 2010 in false?color composite images enhancing ice?snow differentiation and Iterative Self-Organizing (ISO) Data Cluster Unsupervised Classifications were used to 1) quantify the movement rates of Baird, Patterson, LeConte, and Shakes Glaciers ...
