[M-IS04] Paleoclimatology and paleoceanography

Mon. May 25, 2026 9:00 AM - 10:30 AM Exhibition Hall Special Setting (5) (Exhibition Hall 7&8, Makuhari Messe)

Chairperson:Okazaki Yusuke(Department of Earth and Planetary Sciences, Graduate School of Science, Kyushu University), Hasegawa Hitoshi(Faculty of Science and Technology, Kochi University), Westerhold Thomas(Center for Marine Environmental Sciences of the University of Bremen, Bremen, Germany), Nana Yobo Lucien(Texas A&M University College Station), Yamazaki Atsuko(Graduate School of Environmental Studies, Nagoya University)

This session will discuss past environmental changes and events at multi-decadal to tectonic timescales toward an understanding of Earth's climate system by an integration of terrestrial and marine proxy studies and numerical modeling. This session also includes a special series of presentations on elucidating the climate system from the Warmhouse (Pliocene, Miocene) to the Hothouse (Eocene, Cretaceous) periods. We welcome a variety of paleo-environmental studies from a wide range of backgrounds. We hope this session will provide an opportunity to promote communication between participants from multidisciplinary fields.
