[M-IS14] Paleoclimatology and paleoceanography

Thu. May 29, 2025 3:30 PM - 5:00 PM Convention Hall (CH-A) (International Conference Hall, Makuhari Messe)

convener:Takashi Obase(Japan Agency for Marine-Earth Science and Technology), Atsuko Yamazaki(Graduate School of Environmental Studies, Nagoya University), Hitoshi Hasegawa(Faculty of Science and Technology, Kochi University), Yusuke Okazaki(Department of Earth and Planetary Sciences, Graduate School of Science, Kyushu University), 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 JpGU2025, in addition to the regular session, we will have a topic session on highlighting the characteristic of "present-day" climate and ocean from perspective of paleoclimate and paleoceanography. We hope this session will provide an opportunity to promote communication between participants from the multidisciplinary field.
