This session will consist of three parts. Part 1 reviews the collected results of ArCS (2015-2020). Part 2 introduces ArCS II (2020-2025) and its plan, along with strategic goals, priority subjects, and research infrastructures formulated based on the experience of GRENE (2011-2016) Arctic and ArCS. In Part 3, we will have a panel discussion on “Future of Arctic research”. This theme addresses the prospect of Arctic research in general. Taking the implementation cycle of research projects and changes in domestic and international situations of society into consideration, we will broadly discuss the overall picture and future prospects of Arctic research.
