[M-IS15] Paleoclimatology and Paleoceanography

Wed. May 24, 2023 10:45 AM - 12:15 PM International Conference Room (IC) (International Conference Hall, Makuhari Messe)

convener:Yusuke Okazaki(Department of Earth and Planetary Sciences, Graduate School of Science, Kyushu University), Hitoshi Hasegawa(Faculty of Science and Technology, Kochi University), Atsuko Yamazaki(Graduate School of Environmental Studies, Nagoya University), Takashi Obase(Atmosphere and Ocean Research Institute, The University of Tokyo), Chairperson:Atsuko Yamazaki(Graduate School of Environmental Studies, Nagoya University)

We discuss past environmental changes and events at interannual to tectonic timescale toward understanding Earth's climate system by integrating terrestrial and marine proxy studies and numerical modeling. At JpGU2023, in addition to the regular session, we will have a topic session on innovative methodology and non-conventional research during post COVID-19 time. We hope that this session will provide an opportunity to promote communication between participants from the multidisciplinary field.
