In this study, the eddy activity at three major Southern Hemisphere western boundary currents systems (i.e. the Agulhas System, the Brazil-Malvinas Confluence and the East Australia Current) has been inferred through several eddy variables (ie., radius, propagation speed, lifetime). The data was obtained from an eddy tracking dataset developed after Sea Surface Height (SSH) AVISO Reference fields between January/1993 and December/2010. In all three systems the studied eddies presented geographical segregation according to their spatial scales. Besides, it was evident that larger eddies presented a homogeneous propagation direction, usually translating due to their β-induced propulsion. Eddies presented seasonal and interannual variations in shedding frequency.
