The term 'ANTARCTICA's ___ Coast' can be filled in with two words: Adelie and Caird. The Adelie Coast is a section of the Antarctic coastline located between the Ross Sea and the Weddell Sea. It is named after the Adelie penguin, which is native to the region. The Caird Coast is located on the eastern side of the Antarctic Peninsula and is named after Sir John Caird, a British explorer who was part of the first expedition to circumnavigate ANTARCTICA.
