Territorial waters

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 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 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 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 the bay must also be no more than in length. == Internal waters ==

Internal waters are landward of the baseline. The coastal state has sovereignty over internal waters, and can 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 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 ==

and exclusive economic zone of some Southeast Asia and Pacific countries Territorial sea is a belt of sovereign water that extends at most from the baseline of a coastal state, including the airspace over and seabed below it. Although the territorial sea is sovereign territory, foreign ships (military and civilian) are allowed innocent passage. Boundaries can be adjusted through maritime delimitation. If the 12 nautical mile boundary of a state overlaps with the same boundary of another state, the border is taken as the median point between the states' baselines, unless they 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 the US. Two conflicts occurred in the Gulf of Sidra where Libya drew a line in excess of 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. == Contiguous zone ==

The contiguous zone is a band of water extending farther from the outer edge of the territorial sea to up to from 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 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 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. == Exclusive economic zone ==

The exclusive economic zone (EEZ) is a band of water extending from the outer edge of the territorial sea to up to from the baseline 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 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 is still popularly, but incorrectly, regarded as coastal nation's territorial waters. == Continental shelf ==

Definition Article 76 of the UN convention defines the "continental shelf" of coastal countries. A state's continental shelf extends to the outer edge of the continental margin but at least from the baselines of the territorial sea if the continental margin does not stretch that far. Coastal states can explore and exploit 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 of the baseline or beyond from the isobath, which is a line connecting 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: : *a series of lines joining points not more than apart where the thickness of sedimentary rocks is at least 1% of the height of the continental shelf above the foot of the continental slope; or : *a series of lines joining points not more than 60 nautical miles apart that is not more than 60 nautical miles from the foot of the continental margin. The foot of the continental slope is determined as the point of maximum change in the gradient at its base. Extended continental shelf 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 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 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 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. Rights over the continental shelf 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 the shelf that are beyond its exclusive economic zone. This gives it the right to conduct hydrocarbon exploration and drilling works. == Background ==

From the 18th century until the mid-20th 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 a sovereign state could defend from shore. However, Iceland claimed , Norway and Sweden claimed , and Spain claimed during this period. During incidents such as nuclear weapons testing and fisheries disputes some nations arbitrarily extended their maritime claims to as much as or even . Since the late 20th century the "12 mile limit" has become almost universally accepted. The United Kingdom extended its territorial waters from by the '''''' (c. 49). 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 the adjacent continental shelf and fishing were 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 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 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 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 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. == Miscellaneous ==

Pirate radio broadcasting from artificial marine fixtures or anchored ships can be controlled by 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 the United States, divide control over certain waters between the federal government and the individual states. (See tidelands.) == Territorial sea claim ==
