                        •  The East Madagascar Current  (EMC) retroflection is assessed. Evidence of EMC early retroflection is 

                          demonstrated for the first time

                        • Retroflection regimes are associated with EMC strength and mesoscale variability

                        • Knowledge of the EMC retroflection state helps understand regional ecosystem variability
