Argentine Sea

The Argentine Sea (Spanish: Mar Argentino) is the name given to the sea within the continental shelf off the Argentine mainland. It lacks international recognition but is symbolically important to Argentina for consolidating the country's national unity behind the concept of Argentina Grande, an area that extends out to include the British South Atlantic islands and a section of the Antarctic continent.[1]

Geography

The Argentine Sea is 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 mi (800 km) north of Antarctica. The Argentine Sea has a surface area of 1,000,000 km2 (390,000 sq mi)[2] and is one of the largest seas in the world. The average depth of the sea is 1,205 m (3,952 ft) and the maximum depth is 2,224 m (7,296 ft). It has a salinity of 3.5%.[2]

The Argentine Sea progressively widens going southward, in contrast to the narrowing of the continental mass.[2] The sea platform has a series of plateaux which descend to the east as large terraces or steps. Because of its stair-shaped plateaux, 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 territorial waters of Argentina extend 12 nautical miles (22 km; 14 mi) from the line from the gulfs of San Matías and San Jorge to the outer limits of the River Plate. The contiguous zone extends 12 nautical miles after the territorial waters, and the exclusive economic zone 200 nautical miles (370 km; 230 mi) 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 Islands and similar claims around South Georgia and the South Sandwich Islands. The UK's 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.[3]

Argentina announced its claim without consultation with the United Kingdom. In the years 1990 to 2005 fishing and mineral resources in the area were administered 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,[4] 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.[5]

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.

Biodiversity

The Argentine sea is one of the most 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.[6]

The Argentine sea has twelve areas identified as places of great biodiversity. There are two international protected areas, one national, and eighteen provincial ones.[6]

The Argentine sea has plankton, algae, crustaceans, sardines and anchovies. Those feed the more advanced fauna such as penguins, cormorants, sharks, whales, dolphins, Burmeister's porpoise, fur seals, sea lions, and southern elephant seals.

gollark: Language OBVIOUSLY needs this, because we currently use CSMA/CD and it's bad.
gollark: 802.11ax has OFDMA, which is meant to split up a channel into many subchannels so things can operate simultaneously.
gollark: Hmm, what if OFDMA in language?
gollark: Oh, yes, we have backdoors in the concept of anime.
gollark: Also MIMO.
