[M-IS17] Paleoclimatology and paleoceanography

Mon. May 23, 2016 3:30 PM - 5:00 PM A04 (APA HOTEL&RESORT TOKYO BAY MAKUHARI)

Convener:*Tomohisa Irino(Faculty of Environmental Earth Science, Hokkaido University), Minoru Ikehara(Center for Advanced Marine Core Research, Kochi University), Akira Oka(Atmosphere and Ocean Research Institute, The University of Tokyo), Yusuke Okazaki(Department of Earth and Planetary Sciences, Graduate School of Science, Kyushu University), Ikuko Kitaba(Research Centre for Palaleoclimatology, Ritsumeikan University), Akihisa Kitamura(Institute of Geosciences, Faculty of Science, Shizuoka University), Masaki Sano(Research Institute for Humanity and Nature), Ryuji Tada(Department of Earth and Planetary Science, Graduate School of Science, The Univeristy of Tokyo), Takeshi Nakagawa(Ritsumeikan University), Akira Hayashida(Department of Environmental Systems Science, Doshisha University), Chair:Ryuji Tada(Department of Earth and Planetary Science, Graduate School of Science, The Univeristy of Tokyo)

We discuss past environmental changes and events at multi-decadal to tectonic timescale toward an understanding of Earth climate system by an integration of terrestrial and marine proxy studies and numerical modeling. We welcome a variety of paleo-environmental studies from a wide range of background.
This session includes a special series of presentations on the establishment of the high-resolution paleoclimate observatory network. Having robust knowledge on magnitudes, frequencies, spatial patterns, and mechanisms of past climatic changes is a prerequisite to understand near future climatic changes. However, existing paleo-climatic records do not have sufficient spatio-temporal resolutions and age precision to address key questions. Therefore, the target topics and discussions expected here will be the frontier researches for establishing high temporal resolution continuous paleoclimatic archives such as the varved sediments from the Lake Suigetsu and sediment cores from the Japan Sea collected by the recent IODP Expedition 346, correlating these paleoclimatic archives based on precise age determination and key beds, and potential utilization of the paleoclimatic observatory network for reconstruction and analyses of environmental regime in the past.
We hope that this session will provide an opportunity to promote communication between participants from multidisciplinary field.
