Chemosynthetic communities are distributed at hydrothermal system and/or cold seep in bathal zone. They gain their energy from chemosynthetic bacteria, a symbiotic life. The chemosynthetic communities have changed in their taxonomic composition and spatial distribution through the Earth history, but the causes and background remain to be unclear.
Mud volcano is one of geological features which derives fluid nd sediment from depth to the Earth's surface and make topographic feature. It plays a role of carbon cycling connecting depth and surface, pipe of life in depth, disaster and civil engineering. Mechanism and activity of mud volcanoes, however, are not enough understood yet. Mud volcano in Japan is mostly active in offshore fields and are frequently accompanying cold seeps at around it.
Here we propose a joint session with Chemosynthetic communities and Mud volcanoes to have cross-cutting discussion between us. Topics relates to mud volcano will help discussion of evolution of communities and chemosynthetic communities will help to understand mud volcano activity along time and space. Study results for usual two sessions, for cross-cutting discussions, and from related settings are absolutely welcome.
