The Ninth Symposium on Polar Science (4 – 7 December 2018)

Oral sessionPoster session

Interdisciplinary session
[IA] Open session for the interdisciplinary Arctic Science


This session invites presentations from the wide range of the topics related to the Arctic, including all disciplines of natural sciences, engineering, humanities and social sciences.
The Arctic is experiencing rapid environmental and amplified climatic changes, creating significant challenges for people living in this region and various impacts around the globe, which is cascading to the all level of environment in various time scales. We have been trying to elucidate the whole pictures of these changes in the Arctic and their phenomena, but many open questions still remain. Arctic change also has impacts on the global climate as well as ecosystems and human societies in higher-middle latitudes, which is also a scope of the session.
We welcome the contributions on the latest findings on the ongoing change in the Arctic, as well as its past change and perspectives on future change, improved understanding of processes and mechanism, its impact on our society.

Conveners : Tetsuo Sueyoshi, Yuji Kodama, Hiroshi Miyaoka, Kumiko Goto-Azuma, and Hiroyuki Enomoto (NIPR)
