How this entity was disambiguated
This entity first appeared as the object of triple T1236160 — 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.

C.
North Atlantic subtropical gyre
The North Atlantic subtropical gyre is a large, clockwise-rotating system of ocean currents in the North Atlantic Ocean that plays a key role in heat transport, climate regulation, and the distribution of marine life.
-
D.
Indian Ocean subtropical gyre
The Indian Ocean subtropical gyre is a large, clockwise-rotating system of ocean currents in the southern Indian Ocean that plays a key role in heat transport, climate regulation, and marine ecosystems.
-
E.
Ekman transport
Ekman transport is an oceanographic process in which wind-driven surface waters move at an angle to the wind direction due to the Coriolis effect, causing net water transport perpendicular to the wind.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

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
Subject: global thermohaline circulation Description of subject: Global thermohaline circulation is the planet-spanning system of deep and surface ocean currents driven by differences in temperature and salinity, which redistributes heat, nutrients, and gases around the world’s oceans.
