Target entity: New Guinea Coastal Undercurrent Context triple: [South Equatorial Current (Pacific Ocean), flowsTowards, New Guinea Coastal Undercurrent]
-
A.
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.
-
B.
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.
-
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.
Leeuwin Current
The Leeuwin Current is a warm ocean current that flows southward along the western coast of Australia, strongly influencing the region’s climate and marine ecosystems.
-
E.
Panama Current
The Panama Current is a warm ocean current in the eastern Pacific that flows westward from the Central American coast, influencing regional marine climates and ecosystems.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
