How this entity was disambiguated

This entity first appeared as the object of triple T7010586 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Arctic Mid-Ocean Ridge system
Context triple: [Nansen-Gakkel Ridge, partOf, Arctic Mid-Ocean Ridge system]

A. South Atlantic mid-ocean ridge system
The South Atlantic mid-ocean ridge system is a major underwater mountain chain where tectonic plates diverge in the South Atlantic Ocean, creating new oceanic crust and hosting features such as the Bouvet Triple Junction.
B. Indian Ocean Ridge system
The Indian Ocean Ridge system is a vast mid-ocean ridge network in the Indian Ocean where tectonic plates diverge and new oceanic crust is formed.
C. Alpha–Mendeleev Ridge complex
The Alpha–Mendeleev Ridge complex is a large submarine volcanic ridge system in the Arctic Ocean, forming part of the ocean floor topography between the Eurasian and Amerasian basins.
D. Mid-Atlantic Ridge
The Mid-Atlantic Ridge is a vast underwater mountain range and divergent tectonic plate boundary running down the center of the Atlantic Ocean, where new oceanic crust is formed.
E. Atlantic–Antarctic Ridge system
The Atlantic–Antarctic Ridge system is a major mid-ocean ridge complex in the South Atlantic and Southern Ocean where tectonic plates diverge and new oceanic crust is formed.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
