[M-IS15] Evolution of Pelagic Realm

Mon. May 27, 2019 3:30 PM - 5:00 PM 302 (3F)

convener:Atsushi Matsuoka(Department of Geology, Faculty of Science, Niigata University), Katsunori Kimoto(Japan Agency for Marine-Earth Science and Technology), Toshiyuki Kurihara(Graduate School of Science and Technology, Niigata University), Tetsuji Onoue(Earth and Environmental Sciences, Graduate School of Science and Technology, Kumamoto University), Chairperson:Atsushi Matsuoka, Toshiyuki Kurihara

This session focuses on the evolution of ecosystem in the pelagic realms,
including discussions on all aspects of pelagic biota covering biostratigraphy,
biochronology, evolution, and biogeography, which are important to the
reconstruction of the spatio-temporal framework in the pelagic realm.
Reconstructions of plate configuration through time are included in the scope of
this session. Biological, geochemical, sedimentological approaches to the
pelagic environments are welcomed.
