United Nations Convention on the Law of the Sea in the context of "Gibraltar Strait"

The Strait of Gibraltar, also known as the Straits of Gibraltar, is a narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Europe from Africa.The two continents are separated by 7.7 nautical miles (14.2 kilometers, 8.9 miles) at its narrowest point. Ferries cross between the two continents every day in as little as 35 minutes. The Strait's depth ranges between 300 and 900 metres (980 and 2,950 feet; 160 and 490 fathoms).

The strait lies in the territorial waters of Morocco, Spain, and the British overseas territory of Gibraltar. Under the United Nations Convention on the Law of the Sea, foreign vessels and aircraft have the freedom of navigation and overflight to cross the strait of Gibraltar in case of continuous transit.

A maritime boundary is a conceptual division of Earth's water surface areas using physiographical or geopolitical criteria. As such, it usually bounds areas of exclusive national rights over mineral and biological resources, encompassing maritime features, limits and zones. Generally, a maritime boundary is delineated at a particular distance from a jurisdiction's coastline. Although in some countries the term maritime boundary represents borders of a maritime nation that are recognized by the United Nations Convention on the Law of the Sea, maritime borders usually serve to identify the edge of international waters.

Maritime boundaries exist in the context of territorial waters, contiguous zones, and exclusive economic zones; however, the terminology does not encompass lake or river boundaries, which are considered within the context of land boundaries.

An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine resources, including energy production from water and wind.

It stretches from the outer limit of the territorial sea (22.224 kilometres or 12 nautical miles from the baseline) out 370.4 kilometres (or 200 nautical miles) from the coast of the state in question. It is also referred to as a maritime continental margin and, in colloquial usage, may include the continental shelf. The term does not include either the territorial sea or the continental shelf beyond the 200 nautical mile limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's rights below the surface of the sea. The surface waters are international waters.

Territorial waters are informally an area of water where a sovereign state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone, and potentially the extended continental shelf (these components are sometimes collectively called the maritime zones). In a narrower sense, the term is often used as a synonym for the territorial sea.

Vessels have different rights and duties when passing through each area defined by the United Nations Convention on the Law of the Sea (UNCLOS), one of the most ratified treaties. States cannot exercise their jurisdiction in waters beyond the exclusive economic zone, which are known as the high seas.

An archipelagic state is a state that rules an island country, consisting of one or more archipelagos. The designation is legally defined by the United Nations Convention on the Law of the Sea of 1982 (UNCLOS III). The Bahamas, Fiji, Indonesia, Papua New Guinea, and the Philippines are the five original sovereign states that obtained approval in the UNCLOS signed in Montego Bay, Jamaica, on 10 December 1982 and qualified as archipelagic states.

An archipelagic state can designate the waters between the islands as sovereign archipelagic waters.

Maritime law or admiralty law is a body of law that governs nautical issues and private maritime disputes. Admiralty law consists of both domestic law on maritime activities, and private international law governing the relationships between private parties operating or using ocean-going ships. While each legal jurisdiction usually has its own legislation governing maritime matters, the international nature of the topic and the need for uniformity has, since 1900, led to considerable international maritime law developments, including numerous multilateral treaties.

Admiralty law, which mainly governs the relations of private parties, is distinguished from the law of the sea, a body of public international law regulating maritime relationships between nations, such as navigational rights, mineral rights, and jurisdiction over coastal waters. While admiralty law is adjudicated in national courts, the United Nations Convention on the Law of the Sea has been adopted by 167 countries and the European Union, and disputes are resolved at the ITLOS tribunal in Hamburg.

A multilateral treaty or multilateral agreement is a treaty to which two or more sovereign states are parties. Each party owes the same obligations to all other parties, except to the extent that they have stated reservations. Examples of multilateral treaties include the Convention Relating to the Status of Refugees, the United Nations Convention on the Law of the Sea, the Geneva Conventions, and the Rome Statute of the International Criminal Court.
