36-502: Extended from Irish territorial waters , and comprising an area of more than 100,000 square kilometres (39,000 sq mi), the ICB stretches from Waterford Harbour to Slyne Head , and follows the 200-metre (110-fathom) bathymetric contour line along its western side. Fishing by certain vessels and vessel types is restricted in this area, and vessels over 10 metres (33 ft) long are required to report their catch and movements to

72-499: A coastal state. The territorial sea is sovereign territory, although foreign ships (military and civilian) are allowed innocent passage through it, or transit passage for straits ; this sovereignty also extends to the airspace over and seabed below. In international law, adjustment of these boundaries is called maritime delimitation . A state's territorial sea extends up to 12 nmi (22 km; 14 mi) from its baseline. If this overlaps with another state's territorial sea,

108-466: A sovereign state could defend from shore. However, Iceland claimed two nautical miles (3.7 km), Norway and Sweden claimed four nautical miles (7.4 km), and Spain claimed six nautical miles (11 km) during this period. During incidents such as nuclear weapons testing and fisheries disputes some nations arbitrarily extended their maritime claims to as much as fifty nautical miles (93 km) or even two hundred nautical miles (370 km). Since

144-436: 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

180-414: Is a general right enjoyed in international waters; "freedom of navigation operations" enforces this right, in some cases to counter a claim by a sovereign state that certain waters are territorial. Initially, the right of innocent passage in the current sense began to take shape in the 1840s (as a customary rule ) with the development of world trade and the emergence of steamships navigation, for which it

216-492: Is still popularly, but incorrectly, regarded as coastal nation's territorial waters. Article 76 of the UN convention defines "continental shelf" of coastal countries. A state's continental shelf extends to the outer edge of the continental margin but at least 200 nautical miles (370 km; 230 mi) from the baselines of the territorial sea if the continental margin does not stretch that far. Coastal states can explore and exploit

252-645: The Irish Fisheries ' patrol. The Irish Naval Service is tasked with enforcing the special protection measures. The Irish Conservation Box replaces a previous protection zone - known as "the Irish Box" - which was a larger rectangular 50-mile zone around the whole coast of the island of Ireland and included waters reaching to the western coasts of Scotland, England and Wales. Under the (original) Irish box mandate, important spawning and nursery areas for many stocks were protected by - for example - limiting fishing in

288-561: 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 . Normally, the baseline is the low-water line along the coast as marked on large-scale charts that the coastal state recognizes. This is either the low-water mark closest to

324-570: The Common Fisheries Policy, and after intense negotiations on a proposal by the then Minister for Communications, Energy and Natural Resources , the Fisheries Council accepted the position that protection of biologically sensitive areas was critical to a conservation policy. The renewed Irish Conservation Box regulations came into force in 2004. Territorial waters Territorial waters are informally an area of water where

360-571: The Law of the Sea Article 19 defines innocent passage as: Underwater vehicles like submarines are required by the treaty to surface and show their flags during innocent passage. Innocent passage applies to the entire territorial sea , up to at most 12 nautical miles (22 km; 14 mi) from coastal baseline. Transit passage is a similar right that applies only to straits that divide two areas of international waters ; it has different requirements for transiting vessels. Freedom of navigation

396-479: The Philippines, are also internal waters, but the state must allow innocent passage through them. However, archipelagic states can limit innocent passage to designated sea lanes within these waters. Each island in the archipelago can have its own baseline. Territorial sea is a belt of coastal waters extending at most 12 nautical miles (22 km; 14 mi) from the baseline (usually the mean low-water mark) of

432-629: The Subsoil and Sea Bed of the Continental Shelf", and stipulated in its operative clause: the Government of the United States regards the natural resources of the subsoil and sea bed of the continental shelf beneath the high seas but contiguous to the coasts of the United States as appertaining to the United States, subject to its jurisdiction and control. The second proclamation was titled "Policy of

468-633: The US presidential proclamation, the issue of legally determining territorial waters by international agreement was raised, and in its first session in 1949, the International Law Commission of the United Nations added the subject to its agenda. The important issue of the breadth of territorial waters could not be resolved at either the UNCLOS I (1956-1958) or UNCLOS II (1960) conferences, with neither

504-512: The US. Two conflicts occurred in the Gulf of Sidra where Libya drew a line in excess of 230 nmi (430 km; 260 mi) and claimed the entire enclosed gulf as its territorial waters. The US exercised freedom of navigation rights, resulting in the 1981 and 1989 Gulf of Sidra incidents. The contiguous zone is a band of water extending farther from the outer edge of the territorial sea to up to 24 nautical miles (44.4 km; 27.6 mi) from

540-592: The United States With Respect to Coastal Fisheries in Certain Areas of the High Seas", and stated in its operative clause: the Government of the United States regards it as proper to establish conservation zones in those areas of the high seas contiguous to the coasts of the United States wherein fishing activities have been or in the future may be developed and maintained on a substantial scale. Following

576-637: The United States, divide control over certain waters between the federal government and the individual states. (See tidelands .) Maritime controversies involve two dimensions: (a) territorial sovereignty, which are a legacy of history; and (b) relevant jurisdictional rights and interests in maritime boundaries , which are mainly due to differing interpretations of the law of the sea. As of 13 May 2009, 51 submissions by 44 countries have been lodged for claims over their extended continental shelf. Some countries have multiple submissions and joint submissions with other countries. Recommendations have been given for 8 of

612-531: The adjacent continental shelf and fishing was first made by the United States government immediately following the Second World War . On 28 September 1945, US President Harry S. Truman issued two proclamations that established government control of natural resources in areas adjacent to the coastline. One of these proclamation was titled "Policy of the United States With Respect to the Natural Resources of

648-735: The affected coastal nation or other nations wherever that broadcast may originate, whether in the territorial sea, exclusive economic zone, the continental shelf or even on the high seas . Thus a coastal nation has total control over its internal waters, slightly less control over territorial waters, and ostensibly even less control over waters within the contiguous zones. However, it has total control of economic resources within its exclusive economic zone as well as those on or under its continental shelf. Throughout this article, distances measured in nautical miles are exact legal definitions, while those in kilometres are approximate conversions that are not stated in any law or treaty. Federal nations, such as

684-459: The baseline. Inside, a state can exercise limited control to prevent or punish "infringement of its customs, fiscal, immigration or sanitary laws and regulations within its territory or territorial sea". The zone is typically 12 nautical miles (22 km; 14 mi) wide. However, it can be wider when a state claims a territorial sea of less than 12 nautical miles, or narrower if it would otherwise overlap with another state's contiguous zone. Unlike

720-596: The basis of their claim to the UN Commission on the Limits of the Continental Shelf. The Commission then validates or makes recommendations on the scientific basis for the extended continental shelf claim. The scientific judgement of the Commission shall be final and binding. Validated extended continental shelf claims overlapping any demarcation between two or more parties are decided by bilateral or multilateral negotiation, not by

756-457: The bay must also be no more than 24 nautical miles (44 kilometres; 28 statute miles) in length. Internal waters are landward of the baseline. The coastal state has sovereignty over internal waters, enforce domestic law on vessels in internal waters, including to prohibit innocent passage . Lakes, rivers and bays are considered internal waters. "Archipelagic waters" within the outermost islands of an archipelagic state , such as Indonesia or

792-504: The border is taken as the median point between the states' baselines, unless the states agree otherwise. A state can also choose to claim a smaller territorial sea. Conflicts have occurred when a coastal nation claims an entire gulf as its territorial waters while other nations only recognize the more restrictive definitions of the UNCLOS. Claims that draw the baseline at more than 24 nautical miles (two 12 nm limits) are judged excessive by

828-421: The commission. Countries have ten years after ratifying UNCLOS to lodge their submissions to extend their continental shelf beyond 200 nautical miles, or by 13 May 2009 for countries where the convention was ratified before 13 May 1999. As of 1 June 2009, 51 submissions have been lodged with the commission, of which eight have been deliberated by the commission and have had recommendations issued. The eight are (in

864-494: The depths of the seabed at 2,500 meters. The outer edge of the continental margin for the purposes of this article is defined as: The foot of the continental slope is determined as the point of maximum change in the gradient at its base. The portion of the continental shelf beyond the 200 nautical mile limit is also known as the "extended continental shelf". Countries wishing to delimit their outer continental shelf beyond 200 nautical miles have to submit scientific information for

900-457: The late 20th century the "12 mile limit" has become almost universally accepted. The United Kingdom extended its territorial waters from three to twelve nautical miles (5.6 to 22.2 km) in 1987. During the League of Nations Codification Conference in 1930, the issue of establishing international legislation on territorial waters was raised, but no agreement was reached. Claims by legislation to

936-447: The mouths of bays. In this case, a bay is defined as "a well-marked indentation whose penetration is in such proportion to the width of its mouth as to contain land-locked waters and constitute more than a mere curvature of the coast. An indentation is not, however, regarded as a bay unless its area is as large as, or larger than, that of the semi-circle whose diameter is a line drawn across the mouth of that indentation". The baseline across

972-465: The order of date of submission): Russian Federation; Brazil; Australia; Ireland; New Zealand; the joint submission by France, Ireland, Spain and the United Kingdom; Norway and Mexico. Articles 77 to 81 define the rights of a country over its continental shelf. A coastal nation has control of all resources on or under its continental shelf, living or not, but no control over any living organisms above

1008-406: The seabed and the natural resources on or beneath it. However, other states may lay cables and pipelines if authorized by the coastal state. The outer limit of a country's continental shelf cannot stretch beyond 350 nautical miles (650 km; 400 mi) of the baseline or beyond 100 nautical miles (190 km; 120 mi) from the 2,500 metres (8,200 ft) isobath , which is a line connecting

1044-481: The shelf that are beyond its exclusive economic zone. This gives it the right to conduct hydrocarbon exploration and drilling works. From the eighteenth century until the mid twentieth century, the territorial waters of the British Empire , the United States, France and many other nations were three nautical miles (5.6 km) wide . Originally, this was the distance of a cannon shot, hence the portion of an ocean that

1080-438: 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 (such as mud flats) is within 3 nautical miles (5.6 kilometres; 3 + 1 ⁄ 2 statute miles) of permanently exposed land. Straight baselines can alternatively be defined connecting fringing islands along a coast, across the mouths of rivers, or with certain restrictions across

1116-480: The submissions. List with date of submission and adoption of recommendation by the Commission on the Limits of the Continental Shelf. List in order of date of submission, with date of submission. Innocent passage Innocent passage is a concept in the law of the sea that allows for a vessel to pass through the territorial sea (and certain grandfathered internal waters ) of another state, subject to certain restrictions. The United Nations Convention on

1152-542: The surface of the sea that complies with the laws and regulations adopted by the coastal state in accordance with the provisions of the UN Convention, within that portion of its exclusive economic zone beyond its territorial sea. Before the convention, coastal nations arbitrarily extended their territorial waters to attempt to control activities that are now regulated by the exclusive economic zone, such as offshore oil exploration or fishing rights (see Cod Wars ). The EEZ

1188-609: The territorial sea, there is no standard rule for resolving such conflicts and states must negotiate a compromise. The US invoked a contiguous zone out to 24 nmi from the baseline on 29 September 1999. An exclusive economic zone (EEZ) extends from the baseline to almost 200 nautical miles (370.4 km; 230.2 mi) and therefore includes the contiguous zone. A coastal nation has control of all economic resources inside its exclusive economic zone, including fishing, mining, oil exploration, and pollution of those resources. However, it cannot prohibit passage or loitering above, on, or under

1224-496: The two major contenders of a 3-mile or 12-mile limit reaching the required two-thirds support. This lack of agreement had the potential to lead to serious international disputes. It was only at the UNCLOS III (1973-1982) conference, whose provisions did not come into force until 1994, that this issue was resolved at twelve nautical miles. Pirate radio broadcasting from artificial marine fixtures or anchored ships can be controlled by

1260-496: The zone to no more than 40 foreign vessels at any one time. Because of common and "free-movement" policies of the EU , certain countries expected access to the zone in the long-term. As a result, there was ongoing lobbying by Spanish and Portuguese politicians of the Committee on Fisheries to remove the limits, and it was effectively abolished in late 2002. As part of a 2003 review of

1296-422: Was economically significant to use the shortest possible route often through the coastal waters of a foreign state. The law was codified in the 1958 Geneva Convention and affirmed in the 1982 UNCLOS . The coastal state may suspend the innocent passage regime of all foreign ships without discrimination, except in the international straits , where the regime is non-suspendable.
