How this entity was disambiguated

This entity first appeared as the object of triple T2861707 — 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: tropical Atlantic Ocean
Context triple: [sooty tern, distribution, tropical Atlantic Ocean]

A. equatorial Atlantic Ocean
The equatorial Atlantic Ocean is the warm, central belt of the Atlantic that straddles the Earth's equator, connecting the tropical waters of the eastern and western hemispheres and playing a key role in global ocean circulation and climate.
B. Tropical Northwestern Atlantic
The Tropical Northwestern Atlantic is a marine ecoregion characterized by warm, clear tropical waters, coral reefs, and diverse marine life in the western Atlantic Ocean, including areas around the Lucayan Archipelago.
C. eastern Atlantic Ocean
The eastern Atlantic Ocean is the portion of the Atlantic bordering the western coasts of Europe and Africa, encompassing key maritime routes and strategic naval operating areas.
D. South Atlantic subtropical gyre
The South Atlantic subtropical gyre is a large, clockwise-rotating system of ocean currents in the South Atlantic Ocean that plays a key role in global heat transport and climate regulation.
E. Caribbean Sea
The Caribbean Sea is a tropical body of water in the Western Hemisphere known for its clear blue waters, extensive coral reefs, and numerous islands that form the Caribbean region.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
