Short summary
This modelling study aimed to recreate the Agulhas Current transport proxy within a regional HYCOM simulation of the Agulhas Current system, attempting to test the validity of the underlying assumptions on which the satellite-altimeter proxy was based. Results showed that the proxy is sensitive to subsurface variability in the model but that the proxy remained robust regarding the time periods needed to build a sufficient linear relationship between transport and sea surface height slope.
