I’m interested in the dynamics of the Arctic Ocean. It is a complicated space and one which is sparsely observed and difficult to model. This means we still have a lot to learn.
The Arctic is changing rapidly, and hosts systems that are sensitive to change. Although it is a comparitively small ocean, it plays an important role in larger scale ocean circulation and climate.
My research aim is to understand the processes controlling changes in Arctic freshwater content. The fact that the Arcitc is relatively fresh (ie. not so salty) is vitally important for ocean dynamics and the presence and stability of sea-ice. We might expect changes in freshwater content to impact these processes. One high-profile example is that large freshwater fluxes from the Arctic into the sub-polar North Atlantic have the potential to slow the overturning circulation.
The research that I have done so far with my supervisor, Helen Johnson, and collaborators indicates that large-scale patterns of winds can explain past changes in freshwater content, when the memory in this relationship is properly considered.
