| Summary | We conducted three-component electric self-potential, EM induction-loop and magnetic mapping of seafloor massive sulphides (SMS) in the Indian Ocean. Two different deep-towed vehicles have been used to perform high resolution mapping at altitudes of 50 m and 2-3 m above seafloor, respectively. The multi-parameter datasets are expected to provide more accurate models of the 3D structure and especially the subsurface extension of SMS mounds. We present exemplary results of finite element modelling to discuss how multi-geophysical and multi-resolution datasets can be used to explore the individual assets of the applied methods, reduce ambiguities, derive sound interpretations, and finally to gain a better understanding of the resource potential, i.e. the volume and composition of SMS deposits in the deep ocean. |
