Blue ice areas (BIAs) and their geographical distribution in Antarctica were mapped using Landsat-7 ETM+ images obtained during austral summers of 1999-2003 covering the north area of 82.5°S, and snow grain size image of MODIS-based Mosaic of Antarctica (MOA) dataset acquired during the 2003-2004 austral summers from 82.5°S to the South Pole. The results estimated BIAs to occupy 234,549 km2, or 1.65% of the continent. The BIAs were scattered widely over coastal or mountainous regions of the continent but were generally located in Victoria Land, the Transantarctic Mountains, Dronning Maud Land, and the Lambert Glacier basin. The surface slope of most of the BIAs was less than 5 degrees, and only 5.5% of the BIAs had slopes of more than 5 degree primarily located in the Transantarctic Mountains and Victoria Land. The ice velocities of approximately 92.92% of the BIAs were less than 500 meters per year, while ~84% of BIAs exhibited ice velocity of less than 200 meters per year mainly located in the Ross, Shackleton, Amery, Riiserlarsen and Ronne Ice Shelves closely associated with glacier dynamics. The BIAs product has been distributed by National Snow and Ice Data Center of USA.
