The 13th Symposium on Polar Science (15 – 18 November 2022)
Oral session on 17 November │ Poster session on 17 November │ Oral session on 18 November
Interdisciplinary Session
[IA] Arctic Research
Scopes
This session invites presentations from a wide range of 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. We have been trying to elucidate the whole picture of these changes in the Arctic and their phenomena, but many open questions still remain. The 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 mechanisms, its impact on our society.
Conveners : Hiroshi Miyaoka, Teruo Aoki, Kentaro Nishimoto, Hiroyuki Enomoto, and Hironori Yabuki (NIPR)
