Professor Cliff Law’s expertise is in marine biogeochemistry, with a focus on marine trace gases, phytoplankton growth controls, ocean acidification and climate change. He currently leads a MBIE project, CARIM (Coastal Acidification: Rate, Impacts and Management), and a Sustainable Seas Innovation Fund project on mitigating coastal acidification around mussel farms. He has published 100 papers, with recognition via the Prime Ministers Science Team award (2011), the Institute of Chemical Engineers Hutchinson medal (2013), and the University of Otago Science Division Research Group of the Year award (2015). He has coordinated international and national research activities, as a member of the IGBP SOLAS (Surface Ocean Lower Atmosphere Study) steering committee and as co-director of the NIWA-University of Otago Centre for Oceanography (http://www.otago.ac.nz/oceanography/index.html ). He is also a member of the University of Otago Ocean Acidification Theme steering committee and the Marsden ESA Review Panel.

Professor Law teaches undergraduate courses on marine chemistry for the Departments of Chemistry, Marine Sciences and Botany. He also works for the National Institute of Water and Atmospheric Research in Wellington, where he leads the Oceans-Climate Interactions program (https://www.niwa.co.nz/people/cliff-law).
