Agulhas Retroflection

Target entity: Agulhas Retroflection
Context triple: [Agulhas Current, formsFeature, Agulhas Retroflection]

• 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. Subantarctic Front
  The Subantarctic Front is a major oceanographic boundary in the Southern Ocean that separates relatively warm, salty subtropical waters from cooler, fresher subantarctic waters and plays a key role in global heat and nutrient transport.
• C. 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.
• D. Antarctic Convergence
  The Antarctic Convergence is a major circumpolar oceanic boundary where cold Antarctic waters meet and sink beneath warmer sub-Antarctic waters, creating a sharp gradient in temperature and marine ecosystems.
• E. Benguela Current
  The Benguela Current is a cold, northward-flowing ocean current off the southwest coast of Africa, known for its nutrient-rich upwelling that supports highly productive marine ecosystems and major fisheries.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Agulhas Retroflection
Target entity description: 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.
