How this entity was disambiguated
This entity first appeared as the object of triple T23363575 — 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: West Antarctic Ice Sheet Context triple: [Whillans Ice Stream, drainageBasin, West Antarctic Ice Sheet]
-
A.
East Antarctic Ice Sheet
The East Antarctic Ice Sheet is the massive, ancient ice mass covering most of East Antarctica, containing the majority of the continent’s ice and a significant portion of the world’s freshwater.
-
B.
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.
-
C.
Antarctic Peninsula Ice Sheet
The Antarctic Peninsula Ice Sheet is the northernmost and one of the most rapidly warming and changing portions of Antarctica’s ice cover, playing a key role in regional sea-level contributions and climate research.
-
D.
Filchner-Ronne Ice Shelf
The Filchner-Ronne Ice Shelf is one of Antarctica’s largest ice shelves, fringing the southern Weddell Sea and playing a key role in the region’s glaciology and ocean circulation.
-
E.
West Antarctica
West Antarctica is the portion of the Antarctic continent lying mostly west of the Transantarctic Mountains, known for its marine-based ice sheet that is particularly vulnerable to climate change and potential sea-level rise.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
