Methane produced in marine sediments is transported to the seafloor and discharged at cold seeps, mud volcanoes, and hydrothermal vents. The discharged methane and fluids form unique environments, such as methane hydrates, carbonates, and chimneys, and sustain chemosynthetic ecosystems. Methane and the methane-driven phenomena are closely related to the ocean and global environmental changes, material cycles, and evolution of life, making them a key for better understanding of the interactions among Geosphere-Hydrosphere-Biospheres. Deepening and expanding our knowledge of these processes will also contribute to the sustainable development of human society, including resource utilization, disaster prevention, and biodiversity and ecosystem conservation. This session welcomes latest research topics on the geochemical origin of methane and fluids, the geophysical background, resource sciences, and geobiology of chemosynthetic ecosystems at cold seeps, mud volcanoes, and hydrothermal vents, regardless of whether the field is marine or terrestrial, present or past. Based on these topics, we aim to promote active interactions between scientists from multiple fields and the development of a multidisciplinary research community.
All the presentations in this session are given in Japanese or English. However, figures and tables should be prepared in English.
