Seafloor hydrothermal deposits are generated by seafloor hydrothermal activity, and there is growing interest in better understanding its’ origins, not only for science but also for resource utilization.
Against this background, JAMSTEC is conducting research on the origin of seafloor hydrothermal deposits, as a part of a " Next-generation technology for ocean resources exploration", effort of the " cross-ministerial Strategic Innovation Promotion Program (SIP) ".
Artificial hydrothermal vents were created by D/V Chikyu, drilling into a hydrothermal reservoir below the seabed and installing casing pipes and wellheads on the sea floor. After that, LTBMSs to measure temperature, pressure, flow rates, and artificial precipitation in cells, were installed on the artificial hydrothermal vents.
- LTBMSs installed in artificial hydrothermal vents, and equipped with measurement devices and cells (Feb. 2016 and Nov. 2016).
- LTBMS cells recovered by JAMSTEC ROV " KAIKO " (Jan. 2017 and Feb. 2018).
- Succeeded to precipitate hydrothermal deposits in the cells and also simulate the formation process of hydrothermal deposits
- Succeeded in measuring temperature, pressure, and flow rates of hydrothermal flows in an artificial hydrothermal vent.
