Argentine Sea

Argentine Sea, off the atlantic coast of Argentina

The Argentine Sea (Spanish: Mar Argentino) is the sea within the continental shelf off the Argentine mainland.


The Argentine Sea is located in the South Atlantic Ocean off the southeastern coast of Argentina, extending from the approximate latitude of Montevideo, Uruguay, southward to Tierra del Fuego, and is situated about 500 miles (800 km) north of Antarctica. The Argentine Sea has a surface of 386,102 sq. mi. (1,000,000 km²)[1] and is one of the largest seas in the world. The average depth of sea is 3,952 feet (1,205 m) and maximum depth is 7,296 feet (2,224 m). It has a salinity of 35%.[1]

The Argentine Sea progressively widens going southward, in contrast with the narrowing of the continental mass.[1] The sea platform has a series of plateaus which descend to the east as large terraces or steps. Because of its stair-shaped plateaus, the Argentine Sea is similar morphologically to the Extra-Andean Patagonia. The Falkland Islands are also located within the continental shelf of the Argentine Sea.

Territorial claims

According to the law 23968, the exclusive economic zone 200 nautical miles from it. The continental shelf extends to either the limits of the exclusive economic zone or the shelf slope. Argentina has signed and ratified the United Nations Convention on the Law of the Sea.

The exclusive economic zone claimed by Argentina overlap with claims maintained by the United Kingdom on behalf of the Falkland Islanders and similar claims around the Island of South Georgia and the South Sandwich Islands. The UK Falkland Islands claim boundary starts from the midpoint between Argentina and the Islands to the West and stretches 200 nautical miles in other directions with similar claims around the other British Overseas Territories.[2]

Argentina announced its claim without consultation with the United Kingdom and despite the fact that the United Kingdom has administered the area, for the most part peacefully, for over 180 years. In the years 1990 to 2005 fishing and mineral resources in the area were adminsitered by joint commissions between Argentina and the United Kingdom, Argentina unilaterally withdrew from these organisations in 2005 to pursue a more aggressive stance in its claim to the Falkland Islands. At any one time Argentina usually has a single vessel patrolling the undisputed area of its claim,[3] the vessels do not enter the exclusive economic zone of the United Kingdom although there have been reports of Argentine warships threatening vessels on the Falkland side of the border by radio.[4]

Under the terms of the United Nations Convention on the Law of the Sea Article 59 disputed and overlapping claims have no legal force until the dispute is resolved between the opposing parties.


The Argentine sea is one of the highest temperate seas of the world. It receives the cold Falkland Current from the south, which comes from the Antarctic, and the warm Brazil Current from the north.[5]

The Argentine sea has 12 areas identified as places of great biodiversity. There are two international protected areas, one national, and eighteen provincial ones.[5]

The Argentine sea has plankton, algae, crustaceans, sardines and anchovies. Those feed the more advanced fauna such as penguins, cormorants, sharks, whales, sea lions and sea elephants.
