My research includes a broad spectrum of sea-going programs to image and characterize geological structures and phenomena that have the potential to initiate or play a role in natural hazards (e.g., submarine landslides, volcanic plume eruptions, earthquakes, and tsunamis), using state-of-the-art marine electromagnetic (MT/CSEM) technologies and geophysical inverse algorithms. For this purpose, my future sea-going expeditions will focus on the following topics: (a) Elucidate the topography and mechanisms of the oceanic lithosphere-asthenosphere boundary (LAB) and plume beneath volcanic islands, (b) Characterize plate motion at subduction zones, (c) Image passive/active mantle upwelling at ultraslow-to-fast seafloor spreading regions, (d) Study the electrical structure of the seafloor spreading and development of a new oceanic basin, (e) 3-D electrical imaging of large-scale deep submarine groundwater systems offshore the Hawaiian islands and potentially other coastal cities that are currently facing an acute crisis in water supply and seeking for alternative resources, and (f) High-resolution CSEM imaging of marine targets (e.g., CO2 storage, geothermal reservoirs).
