Previous Year Question

The Agulhas Current is a warm ocean current. It is a major western boundary current of the south-western Indian Ocean and generally flows southward along the south-eastern coast of Africa. It transports relatively warm water from the tropical Indian Ocean towards southern Africa.

In contrast, the Canary Current is a cold current of the north-eastern Atlantic Ocean flowing near the north-western coast of Africa. The Humboldt Current, also known as the Peru Current, is a cold current flowing northward along the western coast of South America. Upwelling associated with it brings cold, nutrient-rich deep water to the surface and supports highly productive fisheries along the Peru-Chile coast.

The Oyashio Current is also a cold current. It carries cold subarctic water southward in the North Pacific towards Japan and approaches the region influenced by the warm Kuroshio Current.

Thus, Canary, Humboldt and Oyashio are cold currents, whereas the Agulhas is a warm current. Therefore, the correct answer is (d) Agulhas.
