[M-IS04] Paleoclimatology and paleoceanography

Mon. May 25, 2026 1:45 PM - 3:15 PM Exhibition Hall Special Setting (5) (Exhibition Hall 7&8, Makuhari Messe)

Chairperson: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), Obase Takashi(Japan Agency for Marine-Earth Science and Technology)

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.
