My research is focused on the large-scale dynamics of the Southern Ocean and in particular the role of eddies in modifying the circulation response. The Southern Ocean plays a central role in the dynamics of past and future global climate change, through its control over the transfer of carbon and heat between the deep ocean and atmosphere. However, due to a scarcity of observations and the difficulty of accurately modelling the Southern Ocean, we lack a comprehensive understanding of how the circulation responds to change. The energetic eddy field directly impacts the response of the circulation, but the small scale of the eddies has generally been below the resolution of numerical ocean models. My work utilises high resolution, eddy-resolving simulations to refine our understanding of the eddy field's contribution to Southern Ocean dynamics.
