My research interests lie primarily in the area of the ocean carbon cycle, its variability and predictability on decadal time-scales, as well as its impacts on Earth’s climate via the climate-carbon-cycle feedbacks. These are areas of increasing focus due to my leadership of the WCRP Grand Challenge on Carbon Feedbacks in the Climate System.

    Together with research students and post-docs in my group, as well as with external collaborators, I address knowledge gaps in our understanding of:

    • Predictability of variations in the natural carbon sinks and atmospheric CO2.
    • The regulative role of internal climate variability on decadal trends in the ocean carbon sink and oxygen.
    • Assessing how changes in ocean circulation and biogeochemistry shaped the carbon cycle during ancient warmings and the last glacial cycle.
    • Quantifying the impacts of artificial ocean alkalinity enhancement in the Earth system.

     

    I address these topics in the context of variability and changes in past, present, and future climates. My approach has been to address ocean biogeochemical cycles as an interactive component of the Earth system.
