The Agulhas Undercurrent is a current flowing beneath the Agulhas Current in the western boundary current in the Indian Ocean south of 30 degrees S. Line-Acoustic Dopper Current Profiler (LADCP) measurements indicate the core is centered around 1200 meters, against the continental slope and directly below the surface core of the southwestward flowing Agulhas Current. Maximum velocities of 30 cm/s to the northeast are observed in the undercurrent, and its volume transport is six Sverdrups, about a tenth that of the overlying Agulhas Current.
