Consider the following oceanic currents: I. Oyashio II. Canaries III. Labrador IV. Kuroshio V. Benguela VI. Alaska VII. Humboldt How many of the above are Pacific Ocean currents?
Four
Among the listed currents, the Oyashio (cold current off Kamchatka/Kuril Islands), Kuroshio (warm current off Japan), Alaska Current (warm current in the Gulf of Alaska) and Humboldt/Peru Current (cold current off the west coast of South America) all flow in the Pacific Ocean — four currents in total. The Canaries Current and the Labrador Current belong to the North Atlantic, while the Benguela Current belongs to the South Atlantic. Hence, four of the listed currents are Pacific Ocean currents.
