A detailed study of the mesoscale structure and variability of the upper 500 m layer of the Agulhas Current off Durban has shown that the Agulhas Current is remarkably similar to the other great western boundary currents. At the surface, the Current can generally be divided into 3 distinct zones: the intense cyclonic shear region, the "core" (where the velocity exceeds 1 m/s), and the less well defined anticyclonic shear region....
