[A-CG24] Science in the Arctic Region

Thu. May 26, 2016 1:45 PM - 3:15 PM 304 (3F)

Convener:*Takao Kawasaki(National Institute of Polar Research), Masato Mori(Atmosphere and Ocean Research Institute, University of Tokyo), Hisashi Sato(Department of Environmental Geochemical Cycle Research, Japan Agency for Marine-Earth Science and Technology (JAMSTEC)), Shun Tsutaki(Arctic Environmental Research Center, National Institute of Polar Research), Hiroyasu Hasumi(Atmosphere and Ocean Research Institute, The University of Tokyo), Chair:Hisashi Sato(Department of Environmental Geochemical Cycle Research, Japan Agency for Marine-Earth Science and Technology (JAMSTEC)), Shun Tsutaki(Arctic Environmental Research Center, National Institute of Polar Research)

The Arctic and circumpolar region is the key area for the study of global change because the anthropogenic impact is projected to be the largest in this area due to the complicated feedback processes of the nature. A number of international and interdisciplinary research projects have been conducted for the studies on the land-atmosphere-ocean system. In order to understand the feedback processes occurring in the Arctic and to project the global warming in the future, we need to establish the intense observational network and to exchange the knowledge and information by combining the different scientific communities under the common interest of the Arctic. The objectives of this session are 1) to exchange our knowledge on the observational facts and integrated modelling and 2) to deepen our understanding on wide range of natural sciences related to the Arctic and the circumpolar region. Studies on humanities, social sciences, and interdisciplinary fields are also welcomed.
