Antarctic regions

Target entity: Antarctic regions
Context triple: [HMS Terror, exploredRegion, Antarctic regions]

• A. Amery Ice Shelf region
  The Amery Ice Shelf region is a vast coastal area of East Antarctica dominated by one of the continent’s largest ice shelves, where thick glacial ice flows from the interior into the Southern Ocean.
• 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. Antarctic Treaty area
  The Antarctic Treaty area is the region south of 60° South latitude governed by the Antarctic Treaty System, dedicated to peaceful scientific cooperation and environmental protection.
• D. Campo de Hielo Sur
  Campo de Hielo Sur is a vast Patagonian ice field in southern Chile and Argentina, known as one of the largest extrapolar ice masses in the world.
• E. Maritime Antarctic region
  The Maritime Antarctic region is the relatively mild, coastal zone of Antarctica characterized by oceanic climates, seasonal sea ice, and distinct plant and animal communities compared to the continent’s interior.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
