Answer:
Chilean Antarctic is the name that Chile gives to a sector of Antarctica between the meridians 53°W and 90°W. The sector, which overlaps partially with the areas claimed by Argentina (Argentina Antarctica, between the meridians 53°W and 74°W, south of the 60°S parallel) and by the United Kingdom (British Antarctic Territory, between the meridians 53°W and 80°W south of the same parallel), is claimed by the Republic of Chile as an integral part of its territory.
The territory claimed by Chile includes the South Shetland Islands, the Antarctic Peninsula (called O'Higgins Land in Chile) and adjacent islands, the Alejandro I Island, the Charcot Island, and part of the Ellsworth Land, among others. It has an area of 1 250 257.6 km².
