[A-OS17] Ocean circulation and material cycle in coastal seas

Mon. May 21, 2018 3:30 PM - 5:00 PM 106 (1F International Conference Hall, Makuhari Messe)

convener:Akihiko Morimoto(Ehime University), Kiyoshi Tanaka(University of Tokyo), Yuichi Hayami(佐賀大学, 共同), Kazuhiko Ichimi(Faculty of Agriculture, Kagawa University), Chairperson:Ichimi Kazuhiko, Hayami Yuichi

Costal seas have high biodiversity and high productivity, while various environmental problems such as eutrophication, red tide, and hypoxia are occurred by human activity. In order to understand material cycle and various phenomena and to maintain sustainable environment in costal seas, interdisciplinary research is needed. In the present session, we invite researchers who are interested in physical phenomena, material cycle, biological responsive dynamics, and those interactions in coastal seas. We do not confine study field, area, and method and welcome presentations of wide-range topics. We try to commoditize knowledge in terms of phenomena in coastal seas based on the presentations and discussion.
