Marine Carbon Dioxide Removal aims to remove carbon dioxide from the atmosphere by storing it in the ocean. Techniques that we are interested include Ocean Alkalinity Enhancement and Direct Ocean Capture. The physical dynamics of the ocean play a crucial role in determining the efficacy of such interventions, through the competing effects of air-sea gas exchange, vertical mixing and subduction.
Our research focusses on how physical ocean processes affect the efficacy and environmental impacts of interventions such as OAE. In particular, we are active in the areas of
- The effect of turbulence on dilution rates
- Model validation and uncertainties
- Mixing and nonlinearities in the carbonate system
