| Outline of Final Research Achievements |
We extracted methane from drilled sediment samples from the submarine mud volcano at Kumano basin and the coal-bearing formation off Shimokita. Based on methane clumped isotope, which is a proxy of formation temperature of methane, we revealed the large contribution of microbial methanogenesis in deep subseafloor at both site.
