  abstract = {{T}he {E}ast {M}adagascar {C}urrent ({EMC}) is one of the western boundary currents of the {S}outh {I}ndian {O}cean. {A}s such, it plays an important role in the climate system by transporting water and heat toward the pole and recirculating to the large-scale {I}ndian {O}cean through retroflection modes of its southern extension. {F}ive cruise data sets and remote sensing data from different sensors are used to identify three states of the southern extension of the {EMC}: early retroflection, canonical retroflection, and no retroflection. {R}etroflections occur 47% of the time. {EMC} strength regulates the retroflection state, although impinged mesoscale eddies also contribute to retroflection formation. {E}arly retroflection is linked with {EMC} volume transport. {A}nticyclonic eddies drifting from the central {I}ndian {O}cean to the coast favor early retroflection formation, anticyclonic eddies near the southern tip of {M}adagascar promote the generation of canonical retroflection, and no retroflection appears to be associated with a lower eddy kinetic energy ({EKE}). {K}nowledge of the {EMC} retroflection state could help predict (a) coastal upwelling south of {M}adagascar, (b) the southeastern {M}adagascar phytoplankton bloom, and (c) the formation of the {S}outh {I}ndian {O}cean {C}ounter {C}urrent ({SICC}).},
