[MIS21-01] Integrated multidisciplinary study on change in the Southern Ocean and the Antarctic ice sheet
Keywords:Southern Ocean, Antarctic ice sheet, ocean circulation, ecological system, carbon cycle
The interaction among the atmosphere, ice sheet, solid earth and ocean is vital to understand the Antarctic ice sheet, because the status under ice shelf around the boundary between ice sheet and ocean is essential factor. The physical, biological and chemical processes in the Southern Ocean are extremely important for understanding the carbon cycles which affect the global climate. Moreover, the impact on the ecological system in the Southern Ocean with huge biological production, followed by fluctuations in ocean circulation and sea ice has to be elucidated. Therefore, the primary processes and the mechanism of the interactions should be made clear in the context of the global environmental changes driven by the Antarctic ice sheet and the Southern Ocean throughout the various kinds of the interactions, and the integrated multidisciplinary study is required with the different fields of the observation data from geological to present time scale together with modeling studies. Furthermore, the developments of the observation instruments are important element to obtain the field observation data in the unexplored under and edge of sea ice, that is a key area to understanding the interactions. The program and the framework of the integrated multidisciplinary study focused on the Southern Ocean and the Antarctic ice sheet from the viewpoints of giant reservoirs of heat, water and carbon dioxide, which drive changes in the global climate and ecological system, are introduced, and the future direction and the prospects of this program are discussed.
