[A-OS22] Ocean circulation and material cycle in coastal seas

Wed. May 25, 2022 1:45 PM - 3:15 PM Exhibition Hall Special Setting (2) (Exhibition Hall 8, Makuhari Messe)

convener:Daisuke Takahashi(Tokai University), convener:Naoki Furuichi(Fisheries Technology Institute, Japan Fisheries Research and Education Agency ), Hitomi Yamaguchi(Kagawa University), convener:Akihiko Morimoto(Ehime University), Chairperson:Daisuke Takahashi(Tokai University), Naoki Furuichi(Fisheries Technology Institute, Japan Fisheries Research and Education Agency), Hitomi Yamaguchi(Kagawa University), Akihiko Morimoto(Ehime University)

Coastal seas have high biodiversity and high productivity, while various environmental problems such as eutrophication, red tide, and hypoxia are caused by human activity. In order to understand material cycle and various phenomena and to maintain sustainable environment in the coastal seas, interdisciplinary research is needed. In the present session, we invite researchers who are interested in physical phenomena, material cycle, biological responsive dynamics, and their interactions in the coastal seas. Neither study area nor study method is confined. We welcome presentations of wide-range topics to communize our knowledge in the coastal seas.
