The Convention on the Territorial Sea and Contiguous Zone of 1958 is an international treaty which entered into force on 10 September 1964, one of four agreed upon at the first United Nations Conference on the Law of the Sea (UNCLOS I). 52 states are parties to the convention, whether through ratification, succession, or accession. [1]
Many parties to this convention have since ratified the 1982 United Nations Convention on the Law of the Sea, which came into force in 1994 and supersedes this convention for those states that have ratified UNCLOS.
The United Nations Convention on the Law of the Sea (UNCLOS), also called the Law of the Sea Convention or the Law of the Sea Treaty, is an international treaty that establishes a legal framework for all marine and maritime activities. As of July 2024, 169 States and the European Union are parties.
The terms international waters or transboundary waters apply where any of the following types of bodies of water transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed regional seas and estuaries, rivers, lakes, groundwater systems (aquifers), and wetlands.
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. In a narrower sense, the term is often used as a synonym for the territorial sea.
Law of the sea is a body of international law governing the rights and duties of states in maritime environments. It concerns matters such as navigational rights, sea mineral claims, and coastal waters jurisdiction. The connotation of ocean law is somewhat broader, but the law of the sea is so comprehensive that it covers all areas of ocean law as well.
The International Tribunal for the Law of the Sea (ITLOS) is an intergovernmental organization created by the mandate of the Third United Nations Conference on the Law of the Sea. It was established by the United Nations Convention on the Law of the Sea, signed at Montego Bay, Jamaica, on December 10, 1982. The Convention entered into force on November 16, 1994, and established an international framework for law over all ocean space, its uses and resources. The ITLOS is one of four dispute resolution mechanisms listed in Article 287 of the UNCLOS. Although the Tribunal was established by a United Nations convention, it is not an "organ" of the United Nations. Even so, it maintains close links with the United Nations and in 1997 the Tribunal concluded an Agreement on Cooperation and Relationship between the United Nations and the International Tribunal for the Law of the Sea, which establishes a mechanism for cooperation between the two institutions.
Freedom of navigation (FON) is a principle of law of the sea that ships flying the flag of any sovereign state shall not suffer interference from other states when in international waters, apart from the exceptions provided for in international law. In the realm of international law, it has been defined as “freedom of movement for vessels, freedom to enter ports and to make use of plant and docks, to load and unload goods and to transport goods and passengers". This right is now also codified as Article 87(1)a of the 1982 United Nations Convention on the Law of the Sea.
According to the United Nations Convention on the Law of the Sea, a nation's internal waters include waters on the side of the baseline of a nation's territorial waters that is facing toward the land, except in archipelagic states. It includes waterways such as rivers and canals, and sometimes the water within small bays.
A baseline, as defined by the United Nations Convention on the Law of the Sea, is the line along the coast from which the seaward limits of a state's territorial sea and certain other maritime zones of jurisdiction are measured, such as a state's exclusive economic zone. Normally, a sea baseline follows the low-water line of a coastal state. This is either the low-water mark closest to the shore or an unlimited distance from permanently exposed land, provided that some portion of elevations exposed at low tide but covered at high tide is within 3 nautical miles of permanently exposed land. When the coast is deeply indented, has fringing islands or is highly unstable, straight baselines may be used.
The Convention on the Protection of the Underwater Cultural Heritage is a treaty that was adopted on 2 November 2001 by the General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO). The convention is intended to protect "all traces of human existence having a cultural, historical or archaeological character" which have been under water for over 100 years. This extends to the protection of shipwrecks, sunken cities, prehistoric art work, treasures that may be looted, sacrificial and burial sites, and old ports that cover the oceans' floors. The preservation of underwater cultural heritage is significant as it allows for the retelling of numerous historical events. As part of its duty to conduct scientific research and provide continuous education on the importance of underwater cultural heritage, UNESCO strives to maintain these sites for the enjoyment of current and future generations. The convention may provide a customary framework to help raise awareness and seek to combat the illegal looting and pirating occurring in waters worldwide. As an international body, member states of the convention agree to work towards the preservation of sunken cultural property within their jurisdiction and the high seas.
The Arctic consists of land, internal waters, territorial seas, exclusive economic zones (EEZs) and international waters above the Arctic Circle. All land, internal waters, territorial seas and EEZs in the Arctic are under the jurisdiction of one of the eight Arctic coastal states: Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the United States. International law regulates this area as with other portions of Earth.
Maritime Security Regimes are codes and conventions of behavior agreed upon by coastal states to provide a degree of security within territorial waters and on the high seas.
The Convention on the High Seas is an international treaty which codifies the rules of international law relating to the high seas, otherwise known as international waters. The convention was one of four treaties created at the United Nations Convention on the Law of the Sea. The four treaties were signed on 29 April 1958 and entered into force on 30 September 1962, although in keeping with legal tradition, later accession was permitted.
The Convention on the Continental Shelf was an international treaty created to codify the rules of international law relating to continental shelves. The treaty, after entering into force 10 June 1964, established the rights of a sovereign state over the continental shelf surrounding it, if there be any. The treaty was one of three agreed upon at the first United Nations Convention on the Law of the Sea. It has since been superseded by a new agreement reached in 1982 at UNCLOS III.
The United States was among the nations that participated in the third United Nations Conference on the Law of the Sea, which took place from 1974 through 1982 and resulted in the international treaty known as the United Nations Convention on the Law of the Sea (UNCLOS). The United States also participated in the subsequent negotiations of modifications to the treaty from 1990 to 1994. The UNCLOS came into force in 1994. Although the United States now recognizes the UNCLOS as a codification of customary international law, it has not ratified it.
Transit passage is a concept of the law of the sea, which allows a vessel or aircraft the freedom of navigation or overflight solely for the purpose of continuous and expeditious transit of a strait between one part of the high seas or exclusive economic zone and another. The requirement of continuous and expeditious transit does not preclude passage through the strait for the purpose of entering, leaving or returning from a state bordering the strait, subject to the conditions of entry to that state. The transit passage may be exercised regardless of the nationality (flag) of the ship, its form of ownership, the merchant or government status of a ship or warship, the private or government status of an aircraft.
The exclusive economic zone of Somalia covers 830,389 km2 in the Indian Ocean. It extends to a distance of 200 nautical miles from the baselines, from which the breadth of the nation's territorial waters is measured. In accordance with Law No. 37 passed in 1972, Somalia's EEZ falls under its territorial sovereignty.
International piracy law is international law that is meant to protect against piracy. Throughout history and legal precedents, pirates have been defined as hostis humani generis, Latin for "the enemy of all mankind". The United Nations has codified much of the law in the United Nations Convention on the Law of the Sea (UNCLOS), which defines different types of piracy and ways to combat it.
The exclusive economic zone of Canada is the area of the sea in which Canada has special rights regarding the exploration and use of marine resources, as prescribed by the 1982 United Nations Convention on the Law of the Sea.
Sri Lanka is ranked 51st in size of its exclusive economic zone (EEZ) with a total size of 532,619 km2 (205,645 sq mi). Sri Lanka's EEZ is bordered to the north and west by India in the Gulf of Mannar and Bay of Bengal; as well as in the west by the Maldives in Laccadive Sea.
