[M-IS16] [JJ] Gas hydrates in environmental-resource sciences

Mon. May 22, 2017 9:00 AM - 10:30 AM A02 (Tokyo Bay Makuhari Hall)

convener:Hitoshi Tomaru(Department of Earth Sciences, Chiba University), Akihiro Hachikubo(Environmental and Energy Resources Research Center, Kitami Institute of Technology), Sumito Morita(Institute for Geo-Resources and Environment, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology), Atsushi Tani(Graduate School of Human Development and Environment, Kobe University), Chairperson:Hitoshi Tomaru(Department of Earth Sciences, Chiba University)

An increasing number of researches focusing on natural gas hydrates has recently been conducted from the environmental, material, and resource scientific viewpoints. This session aims to share and discuss the latest research results to understand and examine the nature and potential of gas hydrates in the past-present-future of the Earth. Because the researches on gas hydrates are interdisciplinary, broad topics from field and experimental researches, modeling, etc. will be presented in this session.
