Target entity: Agulhas Return Current Context triple: [Agulhas Retroflection, boundedBy, Agulhas Return Current]
-
A.
Agulhas Current
The Agulhas Current is a powerful western boundary ocean current that flows southward along the southeast coast of Africa, transporting warm, saline water from the tropical Indian Ocean toward the Atlantic.
-
B.
Agulhas Retroflection
Agulhas Retroflection is a major oceanographic feature where the warm Agulhas Current loops back on itself near the southern tip of Africa, shedding eddies that influence global ocean circulation and climate.
-
C.
Mozambique Current
The Mozambique Current is a warm, southward-flowing ocean current in the western Indian Ocean that runs along the coast of Mozambique toward the Agulhas Current.
-
D.
Madagascar Current
The Madagascar Current is a warm oceanic flow that moves southward along the eastern coast of Madagascar, playing a key role in the circulation and climate of the southwest Indian Ocean.
-
E.
Angola Current
The Angola Current is a warm ocean current flowing southward along the west coast of southern Africa, influencing regional climate and marine ecosystems.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
