Application of Time-Domain Electromagnetic Survey for Seafloor Polymetallic Sulphides in the Okinawa Trough

JOGMEC (Japan Oil, Gas and Metals National Corporation) vigorously promotes bathymetric survey, geochemical exploration, geophysical exploration and drilling to evaluate the amount of the resources of the seafloor polymetallic sulphides in Japanese EEZ. Until today several promising ore deposits have been discovered in the Okinawa Trough and Izu-Ogasawara area, and electromagnetic surveys were conducted in several areas. In this presentation, we will introduce some of the WISTEM (Waseda Integrated Seafloor TEM) survey results in the Okinawa Trough in 2018.
