Target entity: Equatorial Undercurrent
Context triple: [Equatorial Countercurrent, relatedTo, Equatorial Undercurrent]

A. Equatorial Countercurrent
The Equatorial Countercurrent is an eastward-flowing ocean current found near the equator that runs between the westward-flowing North and South Equatorial Currents in the world’s major oceans.
B. New Guinea Coastal Undercurrent
The New Guinea Coastal Undercurrent is a subsurface ocean current that flows westward along the northern coast of New Guinea, playing a key role in redistributing heat and salt within the tropical Pacific.
C. Subtropical Countercurrent
The Subtropical Countercurrent is an eastward-flowing ocean current in the North Pacific that runs opposite to the prevailing trade-wind-driven currents within the subtropical gyre.
D. South Equatorial Current
The South Equatorial Current is a major westward-flowing ocean current in the tropical Atlantic, Pacific, and Indian Oceans that plays a key role in global heat transport and climate patterns.
E. North Equatorial Current (regional)
The North Equatorial Current (regional) is a major westward-flowing ocean current in the Pacific that influences circulation, climate, and deep-sea conditions around features such as the Mariana Trench.
F. None of above. chosen
