Chilean Sea

In this article, we will explore the fascinating world of Chilean Sea and its impact on today's society. From its origins to its relevance today, Chilean Sea has been a topic of debate and reflection in various fields, whether in popular culture, politics, science or technology. Throughout history, Chilean Sea has had a significant influence on the way people interact with each other and the environment around them. Through this article, we will examine in detail the different aspects that make Chilean Sea such a relevant and constantly evolving topic.

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

This section is an excerpt from Continental shelf of Chile.

The continental shelf of Chile is 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.

EEZ of Chile
