The Antarctic Maritime Tracker: Chile

This map depicts Chile's internationally submitted sovereignty and sovereign rights claims featured in national legislation with regard to the Antarctic continent and various island and archipelago groups. Click on a feature to learn more about each individual claim. Due to basemap limitations, the full extent of some claims is cut off at the border as the full Sub-Antarctic region cannot be displayed and to place greater emphasis on the main continent.

On November 29, 1984, Argentina and Chile signed the  Treaty of Peace and Friendship between Chile and Argentina , which delimited a portion of a maritime boundary between the two countries. However, on September 23 and 30, 2021, Chile  deposited a new chart  that indicated its rights to the continental shelf south of the extremity of the 1984 maritime boundary. Argentina disputes that these rights can exist, with its Senate  unanimously rejecting the claim  on October 6, 2021.

In areas where sovereignty or sovereign rights are in dispute, we show the claims of each party based on the best publicly available information. ICAS emphasizes that these maps are not to be taken as an endorsement of any one party's respective claims over another's.
