The East Australian Current (EAC) transports heat from the tropics poleward along the east coast of Australia. Whether heat converges or diverges will dictate how the ocean sub-surface temperature changes. Currently, there is little information about the seasonality of heat transport (HT) in the EAC System, and even less for the shelf-offshore exchange. We show a strong seasonal cycle of the key variables (mean and eddy kinetic energy, upper ocean heat content, heat transport), expanding and intensifying in summer, contracting and weakening in winter. When the dynamical regime changes from jet to eddy-dominated at the EAC separation zone, it modifies the net meridional HT. Upstream of separation, HT is poleward, and there is a small zonal convergence. Downstream of EAC separation, heat is recirculated by mesoscale eddies and zonally exported. However, we still don’t know how this heat, under different physical processes, exchanges with the shelf, and how it is related to the observed shelf warming. We explore these questions using a multi-decadal high-resolution model to analyse the cross-shelf HT and the relationship with shelf warming rates. Our results highlight the need for spatially resolved studies of warming rates and processes.
