[M-IS19] [JJ] Biogeochemistry

Wed. May 24, 2017 9:00 AM - 10:30 AM 302 (International Conference Hall 3F)

convener:Muneoki Yoh(Tokyo University of Agriculture and Technology), Hideaki Shibata(Field Science Center fot Northern Biosphere, Hokkaido University), Naohiko Ohkouchi(Japan Agency for Marine-Earth Science and Technology), Youhei Yamashita(Faculty of Environmental Earth Science, Hokkaido University), Chairperson:Yohei Yamashita(Faculty of Environmental Earth Science, Hokkaido University), Chairperson:Naohiko Ohkouchi(Japan Agency for Marine-Earth Science and Technology), Chairperson:Tomoya Iwata(Faculty of Life and Environmental Sciences, University of Yamanashi)

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 further development of biogeochemical studies.
