Dispute over the extended continental shelf in the Southern Zone Sea between Argentina and Chile
The dispute over the extended continental shelf in the Southern Zone Sea between Argentina and Chile is a disagreement between the two countries over a maritime area of 5,302 km2 that began after Argentina attempted to extend its maritime space based on the theory of the extended continental shelf over the Southern Zone Sea (Spanish: Mar de la Zona Austral), south of Point F as agreed in the 1984 treaty, in an area claimed by Chile as part of its "presential sea", and now as part of its continental shelf (not extended) projected from the Diego Ramírez Islands. Previously, Argentina claimed the overlapping "crescent-shaped" area as a "heritage protection sea".
