[M-IS10] Biogeochemistry

Tue. May 26, 2026 10:45 AM - 12:15 PM 104 (International Conference Hall, Makuhari Messe)

Chairperson:Yamashita Youhei(Faculty of Environmental Earth Science, Hokkaido University), Fukushima Keitaro(Fukushima University)

Biogeochemistry is an interdisciplinary study field including ecology, geochemistry, oceanography, limnology, hydrology, soil science, and environmental sciences. Respective researches have tended to be conducted separately so far. This session aims to provide a common platform for biogeochemists of different disciplines, which facilitates the interactive discussion and information exchanges for the further development of biogeochemical studies.
