The Chilean Sea is the portion of the Pacific Ocean lying west of the Chilean mainland. The official Chilean usage for Chilean Sea was defined on 30 May 1974 when the Diario oficial de la Republica de Chile published Supreme Decree #346, which declared that "the waters surrounding or touching the shores of the national territory shall be known as Mar Chileno." [1]

The Chilean Sea contains significant amounts of phosphorite and manganese-iron nodules, which may be potential targets for future seafloor mining. [2]

Continental shelf and extended continental shelf

The continental shelf of Chile refers to the underwater extension adjacent to the Chilean coasts that stretches from the shoreline to the edge of the continental shelf in the Pacific Ocean and the Southern Ocean. [3] [4]

The scientific study and delimitation of the continental shelf and its outer limit are conducted by the National Committee for the Continental Shelf, established in 2007. [5] [6]

The delimitation of Chile's continental shelf follows principles established by the United Nations Convention on the Law of the Sea (UNCLOS), which sets guidelines for the delineation of continental shelves by coastal states. Chile has submitted claims to the United Nations Commission on the Limits of the Continental Shelf.

Apart from its economic importance, the continental shelf also holds geopolitical significance. Its delimitation has occasionally led to tensions with neighboring countries, particularly Argentina, which also claims rights over adjacent maritime areas. [7] [8] [9] [10] [11] Decisions and presentations made to the UN have influenced bilateral relations and Chile's maritime policies, making the continental shelf a critical issue in the country's security and defense agenda.

The face sea, or heritage safeguard sea, is the maritime space that a certain coastal country demarcates, after an oceanopolitical appreciation, in order to indicate to third parties its zone of influence in the high seas adjacent to its exclusive economic zone, where its interests were or could be directly involved.

Without claims of sovereignty, by making a delimitation that includes the effective occupation of the high seas contiguous to its respective oceanic territory, the coastal state shows the interest in preserving said area from abusive uses or from certain activities that, due to its proximity, may affect the marine resources that inhabit its waters, especially, guarding the highly migratory straddling fishery resources from predation, and pollution of the marine habitat.

<span class="mw-page-title-main">Argentina–Chile relations</span> Bilateral relations

International relations between the Republic of Chile and the Argentine Republic have existed for decades. The border between the two countries is the world's third-longest international border, which is 5,300 km (3,300 mi) long and runs from north to south along the Andes mountains. Although both countries gained their independence during the South American wars of liberation, during much of the 19th and the 20th century, relations between the countries were tense as a result of disputes over the border in Patagonia. Despite this, Chile and Argentina have never been engaged in a war with each other. In recent years, relations have improved. Argentina and Chile have followed quite different economic policies. Chile has signed free trade agreements with countries such as China, the United States, Canada, South Korea, as well as European Union, and it's a member of the APEC. Argentina belongs to the Mercosur regional free trade area. In April 2018, both countries suspended their membership from the UNASUR.

The Argentine Sea is a marginal sea of the Atlantic Ocean adjacent to the southern tip of South America. It ranges from the mouth of the estuary of the Río de la Plata in the north to the Isla de los Estados in the south, and from the Argentine coast to the 200 meters isobath. Its width varies between 210 km in front of Mar del Plata and 850 km at the latitude of the Falkland Islands. The coastline extends for 4,725 km. To the east of the Argentine Sea extends much deeper and more extensive Argentine Basin.

Tricontinental Chile is a geopolitical concept denoting Chile's unique position with its mainland in South America, Easter Island in Oceania (Polynesia) and the Chilean Antarctic Territory in Antarctica. This concept is built on the basis that there are Chilean territories as far away from the mainland as to be considered part of Polynesia and on a larger scale, Oceania, and Chile's claims to Antarctica provide it a basis for claiming to be a part of Antarctica as well.

The Argentina–Chile border is the longest international border of South America and the third longest in the world after the Canada–United States border and the Kazakhstan–Russia border. With a length of 5,308 kilometres (3,298 mi), it separates Argentina from Chile along the Andes and on the islands of Tierra del Fuego. However, there are some border disputes, particularly around the Southern Patagonian Ice Field. It is the largest border of the two countries, beating the Argentina–Paraguay and Chile–Bolivia, Argentina's and Chile's second largest borders, respectively.

<span class="mw-page-title-main">Chilean expansionism</span> Foreign policy of Chile

Chilean expansionism refers to the foreign policy of Chile to expand its territorial control over key strategic locations and economic resources as a means to ensure its national security and assert its power in South America. Chile's significant territorial acquisitions, which occurred mostly throughout the 19th century, paved the way for its emergence as a thalassocracy and one of the three most powerful and wealthiest states in South America during the 20th century. It also formed Chile's geopolitical and national identity as a tricontinental state and one of the countries with the longest coastlines in the world.

Spain's exclusive economic zone (EEZ) is the 30th largest in the world with 1,039,233 km2 (401,250 sq mi). It is mostly in the Atlantic Ocean and the Mediterranean Sea. This is approximately double the entire Spanish land area. Together the land and sea surface would account for approximately 0.3% of the world's land surface.

The natural delimitation between the Pacific and South Atlantic Oceans by the Scotia arc is a hydrographical concept developed in Chile in 1952 in which it was postulated that the boundary between the southeast Pacific Ocean and the southwest Atlantic Ocean should not be the meridian of Cape Horn but rather follow the line of the Scotia Arc, an underwater mountain range which links the Tierra del Fuego archipelago with the Antarctic continent.

<span class="mw-page-title-main">Presential sea</span> Zone of influence beyond 200 nautical miles

A presential sea, zone of maritime presence or heritage marine reserve is a zone of influence demarcated by a maritime country in the high seas adjacent to its exclusive economic zone (EEZ). The objective of this oceanopolitical concept or doctrine, is to signal to third parties where the coastal country's interests are, or could be directly involved.

The extended continental shelf, scientific continental shelf, or outer continental shelf, refers to a type of maritime area, established as a geo-legal paradigm by the United Nations Convention on the Law of the Sea (UNCLOS). Through the process known as the extension of the outer limit of the continental shelf or establishment of the outer edge of the continental margin, every coastal state has the privilege, granted by the international community of nations, to acquire exclusive and perpetual rights to exploit the biotic and abiotic resources found on the seabed and subsoil of these maritime areas. These areas are located beyond the 200 nautical miles that make up the state's exclusive economic zone (EEZ) and would otherwise be considered international waters.

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, 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 projected from the Diego Ramírez Islands.
