[M-IS20] Global climate change driven by the Southern Ocean and the Antarctic Ice Sheet

Wed. May 25, 2022 9:00 AM - 10:30 AM 104 (International Conference Hall, Makuhari Messe)

convener:Osamu Seki(Institute of Low Temperature Science, Hokkaido University), convener:Yusuke Suganuma(National institute of Polar Research), Masahiro Minowa(Institute of Low Temperature Science, Hokkaido University), Chairperson:Mutsumi Iizuka(Hokkaido university), Hidetaka Kobayashi(Atmosphere and Ocean Research Institute, The University of Tokyo)

The Southern Ocean and Antarctic ice sheet, which are the giant reservoirs of heat, water, and materials, have a potential to play central roles in long-term global climate change. This system is composed of the following sub-systems; ice shelf which is a place of the interaction of ice sheet and ocean, flowing iceberg, seasonal sea ice zone, Antarctic bottom water which drives the thermohaline circulation, active biological production and Antarctic Circumpolar Current. 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 Southern Ocean, which are essential elements for unraveling the changes in the global climate system. Further, future science plans for understanding of the environmental changes of the Antarctic Cryosphere is also discussed.

9:45 AM - 10:00 AM
