Michael Ellwood

Professor Michael Ellwood is a faculty member at the Research School of Earth Sciences, Australian National University (ANU), specializing in Climate & Ocean Geoscience. He holds a BSc (Hons) from the University of Otago (1993) and a PhD in diatom opal analysis (1998), followed by postdoctoral research at the University of Liverpool and NIWA in New Zealand. His work focuses on trace metal biogeochemistry, ocean acidification impacts, and iron cycling in marine systems.

Research interests include trace element interactions with phytoplankton, analytical techniques for metal isotopes, and the role of ocean acidification on marine organisms. Key projects involve ultra-green hydrogen technologies and Southern Ocean iron dynamics, with supervisory roles in student research. He teaches courses such as Marine Biogeochemistry and Coral Reef Field Studies.

Publications highlight contributions to understanding chromium isotopes in hydrothermal systems, iron's role in phytoplankton growth, and uranium isotope analysis in corals. His work bridges geochemistry, microbiology, and climate science, with fieldwork in the Pacific and Southern Oceans.

No scientific awards are explicitly listed. Advising and grants include leading projects on hydrogen technologies and iron's biogeochemical cycles. His affiliation with ANU's Research School of Earth Sciences supports collaborative efforts in marine geochemistry and climate research.
