It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole:
This claim of 1,250,000 km2 extends between the meridians of 53 and 90 west longitude and from 60 south latitude to the South Pole, partly overlapping with the claims of Argentina and the United Kingdom.
It comprises the region south of 60 S latitude and between longitudes 20 W and 80 W, forming a wedge shape that extends to the South Pole.
It comprises the region south of 60 S latitude and between longitudes 20 W and 80 W, forming a wedge shape that extends to the South Pole, overlapping the Antarctic claims of Argentina (Argentine Antarctica) and Chile (Antártica Chilena Province).
These studies show that during the Cretaceous there were no polar ice caps, and forests would have extended all the way to the South Pole, and life could have flourished there during the summer.
The Treaty of Tordesillas has been invoked by Chile in the 20th century to defend the principle of an Antarctic sector extending along a meridian to the South Pole, as well as the assertion that the treaty made Spanish (or Portuguese) all undiscovered land south to the Pole.
The meridian 169 west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole.
The geography of Chile is extremely diverse as the country extends from a latitude of 17 South to Cape Horn at 56 (if Chilean claims on Antarctica are included Chile would extend to the South Pole) and from the ocean on the west to Andes on the east.
