[M-IS34_2PM1] Southern Ocean and Antarctic Ice sheet: Key to resolve global environmental change

Fri. May 2, 2014 2:15 PM - 4:00 PM 414 (4F)

Convener:*Yoshifumi Nogi(National Institute of Polar Research), Kay I. Ohshima(Institute of Low Temperature Science, Hokkaido University), Minoru Ikehara(Center for Advanced Marine Core Research, Kochi University), Chair:Yoshifumi Nogi(National Institute of Polar Research), Minoru Ikehara(Center for Advanced Marine Core Research, Kochi University)

The Antarctic ice sheet and the surrounding Southern Ocean form the Antarctic Cryosphere, and typical sub-systems of that are ice sheet, sea ice, iceberg, cold surface water, Antarctic bottom water, active biological production and Antarctic Circumpolar Current. These sub-systems are interacted with each others 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 global environmental system, and discuss future science plans for understanding of the environmental changes of the Antarctic Cryosphere.

2:30 PM - 2:45 PM
