The Gulf of Maine Aquarium hosts this two-part activity. The focus is on seasonal changes in the mass balance of the Antarctic Ice Sheet. Part 1 uses an atlas and satellite imagery to examine the geography of the region and the changing boundaries of the ice sheet. Part 2 tracks annual changes in sea ice. There is an animation page showing changes in ice cover around Antarctica during 1991, and links ... Full description.
