[M-IS34] Paleoclimatology and paleoceanography

Thu. May 28, 2015 4:15 PM - 6:00 PM 301A (3F)

Convener:*Kazuyoshi Yamada(Museum of Natural and Environmental history, Shizuoka), Minoru Ikehara(Center for Advanced Marine Core Research, Kochi University), Tomohisa Irino(Faculty of Environmental Earth Science, Hokkaido 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), Takeshi Nakagawa(Ritsumeikan University), Akira Hayashida(Department of Environmental Systems Science, Doshisha University), Chair:Yusuke Okazaki(Department of Earth and Planetary Sciences, Graduate School of Science, Kyushu University)

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 robust correlation. A large number of palaeoclimatic proxy curves are being generated every day. However, many/most of those curves are not robustly placed in the correlation matrix. Robust correlation based on independent criteria such as precisely determined absolute ages and/or key layers is a prerequisite for assessment of relative timings and discussion of mechanisms. The frontier researches for robust and independent correlation will be presented and discussed. We hope that this session will provide an opportunity to promote communication between participants from multidisciplinary field.
