How this entity was disambiguated
This entity first appeared as the object of triple T2945136 — 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.

Target entity: Arctic Intermediate Water Context triple: [Greenland Basin, containsWaterMass, Arctic Intermediate Water]
-
A.
Labrador Sea Water
Labrador Sea Water is a cold, dense, and relatively fresh deep water mass formed by winter convection in the Labrador Sea that contributes significantly to the North Atlantic Deep Water and global ocean circulation.
-
B.
North Atlantic Deep Water
North Atlantic Deep Water is a cold, dense water mass formed in the high-latitude North Atlantic that sinks and flows southward, driving a major component of the global ocean circulation and climate system.
-
C.
Antarctic Bottom Water
Antarctic Bottom Water is a cold, dense water mass formed around Antarctica that spreads along the ocean floor and plays a key role in global deep-ocean circulation and climate regulation.
-
D.
Mediterranean Outflow Water
Mediterranean Outflow Water is a dense, saline water mass originating from the Mediterranean Sea that flows into the Atlantic Ocean, significantly influencing the hydrography and circulation of the eastern North Atlantic.
-
E.
Atlantic Water
Atlantic Water is a warm, salty water mass originating from the North Atlantic Ocean that flows into and influences the hydrography of Arctic basins such as the Nansen Basin.
- 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: Arctic Intermediate Water Description of subject: Arctic Intermediate Water is a cold, relatively fresh mid-depth water mass formed in the Arctic Ocean that spreads into subarctic basins and influences regional ocean circulation and climate.
