| | Abstract | | In recent years, seafloor hydrothermal mineral deposits have been drawing attention as the new metal resources of Japan. In our laboratory the three-component magnetic surveys using ROV (remotely operated vehicle) is performing. Noteworthy point in this approach is that it is possible to acquire high-resolution data since the measurements are taking place very close to the seafloor of 4m. Further, by measuring the three component fields, it is possible to obtain the direction and intensity of the magnetization. The magnetic survey with the ROV was affected with the magnetization of the ROV itself, and to remove the effects, the method of Isezaki (Isezaki, 1986) was introduced. In this study, by using the data obtained in Izena Okinawa, in January 2015, the 3D inversion methods are applied. |
