About

Isobel Yeo is a marine geologist whose research focuses on the formation, evolution, and resource potential of seafloor massive sulphide (SMS) deposits. Her most-cited work, “Geological fate of seafloor massive sulphides at the TAG hydrothermal field (Mid-Atlantic Ridge)” (83 citations), provides critical insights into the long-term stability and preservation of these deep-sea mineral systems. This study is foundational for understanding how SMS deposits—key sources of metals needed for low-carbon technologies—are altered or destroyed over geological timescales, directly informing debates on deep-sea mining feasibility and environmental impact. Yeo’s research bridges volcanology, hydrothermal geochemistry, and economic geology, quantifying the natural degradation rates of these deposits. Her work has been instrumental in shaping international discussions on sustainable resource extraction from the seabed. With a growing citation record, Yeo is recognized for integrating field observations from ocean drilling and submersible expeditions with geochemical modeling, positioning her as a leading voice in the responsible assessment of deep-sea mineral resources.
