Research
Cliff is the Co-Director of the Research Centre for Oceanography, Leader of the NIWA Oceanic Control of Atmospheric Composition Programme, and a Professor in the Department of Marine Chemistry, University of Otago.
Cliff is also a member of the Coastal People: Southern Skies collaboration that connects communities with world-leading, cross-discipline research to rebuild coastal ecosystems.
Coastal People: Southern Skies
His research focuses on the interaction between the ocean and the atmosphere; how biogeochemical cycling in the surface ocean influences atmospheric composition, and how climate variability feedbacks to ocean biogeochemistry. Specific research areas include the production and exchange of trace gases, controls of phytoplankton productivity and biodiversity, and the impact of ocean acidification and climate variability on the structure and functioning of pelagic ecosystems.
He was a member of the International SOLAS Steering Committee for six years, the NZ delegate on the IMO Working Group on Ocean Fertilization for the London Convention, and was awarded the Hutchinson Medal by the Institute of Chemical Engineers in 2013.
