How this entity was disambiguated
This entity first appeared as the object of triple T2161630 — 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.

B.
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.
-
C.
North Brazil Current
The North Brazil Current is a warm western boundary ocean current that carries equatorial waters northwestward along the northeastern coast of South America toward the Caribbean Sea.
-
D.
South Atlantic
The South Atlantic is a U.S. Census Bureau division encompassing several southeastern states along the Atlantic coast, including areas such as Georgia.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
