These sub-systems are interacted with each other and have significant impact on changes in the global environmental system. This session aim to summarize recent observational and simulation studies from various fields relating to the past and present changes in the Antarctic Ice sheet and ocean circulation in the Southern Ocean which is essential element for unraveling the changes in the Erarth's climate system, and discuss future science plans for understanding of the environmental changes of the Antarctic Cryosphere.
