[M-IS21] Gas hydrate in environmental-resource sciences

Tue. May 28, 2019 10:45 AM - 12:15 PM A02 (TOKYO BAY MAKUHARI HALL)

convener:Hitoshi Tomaru(Department of Earth Sciences, Chiba University), Akihiro Hachikubo(Kitami Institute of Technology), Atsushi Tani(Graduate School of Human Development and Environment, Kobe University), Shusaku Goto(Institute for Geo-Resources and Environment National Institute of Advanced Industrial Science and Technology), Chairperson:Naoto Ishida, 戸丸仁

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 associated with natural/experimental gas hydrates to understand and examine the nature and potential of gas hydrates in the past-present-future of the Earth and the development/application for our life. Because the researches on gas hydrates are interdisciplinary, broad topics from field and experimental researches, modeling, etc. will be presented in this session.
