How this entity was disambiguated
This entity first appeared as the object of triple T2208915 — 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.

-
A.
Tasman Front
The Tasman Front is a major oceanic boundary current that separates warm subtropical waters from cooler temperate waters in the Tasman Sea between Australia and New Zealand.
-
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.
Subtropical Countercurrent
The Subtropical Countercurrent is an eastward-flowing ocean current in the North Pacific that runs opposite to the prevailing trade-wind-driven currents within the subtropical gyre.
-
D.
East Luzon Trough
The East Luzon Trough is a deep oceanic trench off the eastern coast of Luzon in the Philippines, formed by the subduction of the Philippine Sea Plate beneath the Philippine Mobile Belt.
-
E.
New Guinea Coastal Undercurrent
The New Guinea Coastal Undercurrent is a subsurface ocean current that flows westward along the northern coast of New Guinea, playing a key role in redistributing heat and salt within the tropical Pacific.
- 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.
