JpGU 2018, the annual meeting of Japan Geoscience Union (JpGU), was held at Makuhari Messe in Chiba from May 20th through 24th, 2018.
“Giant reservoirs of heat/water/material: Global environmental changes driven by the Southern Ocean and the Antarctic Ice Sheet” (Giant Reservoirs – Antarctic) hosted the session M-IS06 entitled “Global climate changes driven by the Southern Ocean and the Antarctic ice sheet” on May 21st and conducted oral and poster sessions. 17 oral sessions (including 2 invited speakers) and 16 poster sessions
During JgGU 2018, “Giant Reservoirs – Antarctic“ also hosted an exhibition booth to introduce the overview, research results, and plans of our project. Both the sessions and exhibition booth successfully gained much interest from many visitors such as researchers who attended M-IS06 oral and poster sessions and undergraduate and high school students who consider their future career path.
[M-IS06] Global climate change driven by the Southern Ocean and the Antarctic Ice Sheet
scope:
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.
