convener:Yusuke Miyajima(Geomicrobiology Research Group, Research Institute for Geo-Resources and Environment, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology), Akira Ijiri(Kobe University), Tomohiro Toki(Faculty of Science, University of the Ryukyus), Hiromi Kayama WATANABE(Japan Agency for Marine-Earth Science and Technology)

On-site poster schedule(2023/5/21 17:15-18:45)

Fluid discharge at cold seeps, mud volcanoes, and hydrothermal vents brings subsurface materials such as methane to the Earth's surface. Unique chemosynthesis-based ecosystems are fueled by the substances provided by the discharged fluids. Knowing the origin of discharged fluids, driving force and geological background of the fluid discharge phenomena are essential to reveal the material cycling in the Earth's interior and the relationship between fluid discharge and environmental changes and natural hazards. Ecology, phylogeny, and fossil records of fluid-dependent organisms provide key to reveal not only the evolution of chemosynthetic organisms but also the interaction between life and Earth. In this session, we welcome topics focusing on geological phenomena and organisms related to cold seeps, mud volcanoes, and hydrothermal vents from a cross-disciplinary perspective of geology, biology, chemistry, and physics. We aim to understand the interaction between geosphere and biosphere both on land and in ocean through Earth history. Talks and discussions in this session will be held in Japanese, though presentation slides and posters may be prepared in English.
