Abstract
We are developing Time Domain EM technologies for the exploration of the ocean bottom hydrothermal mineral deposits. The two measuring systems of moving type and fixed type were introduced in 2012. Currently, new time domain system towed by the ROV was developed. The towing type measurement system promotes highly efficient operation and shows as low noise levels as the fixed type. It was tested at the Okinawa hydrothermal areas, as the results, the mineral deposits are clearly detected by the obtained apparent resistivity anomalies, and the new system is proved to be more practical for the survey of the ocean bottom mineral deposits than the previous two systems we have developed. In addition, we could observe the IP effects of the seabed minerals by the coincident loop measurements.
