Seminar Series (March 25, 2022)

In this seminar, I introduced the audience to marine EM and its various applications using examples from my past and present research. This includes geologic domains such as gas hydrate, the lithosphere-asthenosphere boundary, monitoring CO2 storage, and my recent study revealing a novel freshwater transport mechanism in Hawai‘i. In addition, I outlined my vision to study complex Earth processes associated with natural hazards and resources.

Friday Seminar (October 09, 2020) 

In this seminar, I discussed a novel transport mechanism of freshwater moving from onshore to offshore via a multilayer formation of water-saturated layered basalts, as revealed by marine-controlled source electromagnetic (CSEM) imaging. This newly discovered transport mechanism of fresh water may be the governing mechanism in other volcanic islands. Additionally, water column CSEM imaging detects multiple vertical freshwater plumes extending from the seafloor to the ocean surface. These findings provide valuable information to elucidate hydrogeologic and oceanographic processes affecting biogeochemical cycles in coastal waters worldwide. The results of this research were published in Science Advances (2020), and Geophysical Research Letters (2021).
