Target entity: West Antarctic Ice Sheet
Context triple: [West Antarctica, hasIceSheet, West Antarctic Ice Sheet]
  • A. 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.
  • B. 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.
  • C. Larsen Ice Shelf
    The Larsen Ice Shelf is a large Antarctic ice shelf fringing the eastern coast of the Antarctic Peninsula, known for its dramatic partial collapses that have highlighted the impacts of climate change.
  • D. Ross Ice Shelf
    The Ross Ice Shelf is the world’s largest ice shelf, a vast floating extension of the Antarctic ice sheet that plays a key role in buttressing inland glaciers and influencing global sea-level stability.
  • E. 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.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
