How this entity was disambiguated
This entity first appeared as the object of triple T6746516 — 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.
Whillans Ice Stream
Whillans Ice Stream is a major fast-flowing channel of ice in West Antarctica that drains part of the West Antarctic Ice Sheet into the Ross Ice Shelf.
-
B.
Pine Island Glacier
Pine Island Glacier is one of Antarctica’s largest and fastest-melting glaciers, a major contributor to global sea-level rise located in West Antarctica’s Amundsen Sea sector.
-
C.
Rutford Ice Stream
Rutford Ice Stream is a major fast-flowing glacier in West Antarctica that channels ice from the interior ice sheet toward the Filchner-Ronne Ice Shelf.
-
D.
Antarctic ice shelves
Antarctic ice shelves are vast, floating extensions of the Antarctic ice sheet that fringe the continent’s coastline and play a critical role in regulating global sea levels and climate.
-
E.
Antarctic Ice Sheet
The Antarctic Ice Sheet is the vast, continent-spanning mass of glacial ice covering Antarctica, holding the majority of Earth’s freshwater and playing a critical role in global sea-level and climate regulation.
- 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: West Antarctic outlet glaciers Description of subject: West Antarctic outlet glaciers are fast-flowing ice streams that drain the West Antarctic Ice Sheet into the surrounding oceans, playing a critical role in regional ice loss and global sea-level rise.
