How this entity was disambiguated
This entity first appeared as the object of triple T10376723 — 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.

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.

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.
-
D.
South Pacific Convergence Zone
The South Pacific Convergence Zone is a major band of low-level atmospheric convergence and frequent convection stretching diagonally across the southwest Pacific, strongly influencing regional weather and rainfall patterns.

E.
North Pacific subtropical front
The North Pacific subtropical front is an oceanic boundary zone in the North Pacific where distinct water masses meet, marked by sharp gradients in temperature and salinity and playing a key role in regional circulation and ecosystem dynamics.

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.
