This entry includes the following claims, the definitions of which are excerpted from the United Nations Convention on the Law of the Sea (UNCLOS), which alone contains the full and definitive descriptions:

territorial sea - the sovereignty of a coastal state extends beyond its land territory and internal waters to an adjacent belt of sea, described as the territorial sea in the UNCLOS (Part II). This sovereignty extends to the air space over the territorial sea as well as its underlying seabed and subsoil; every state has the right to establish the breadth of its territorial sea up to a limit of 12 nautical miles. The normal baseline for measuring the breadth is the mean low-water line along the coast. Where the coasts of two states are opposite or adjacent to each other, neither state is entitled to extend its territorial sea beyond the median line.

contiguous zone - this is the zone along a coastal state's territorial sea, where a country may prevent infringement of its customs, fiscal, immigration, or sanitary laws and punish infringement of these laws. The contiguous zone may not extend beyond 24 nautical miles from the baselines from which the breadth of the territorial sea is measured (e.g., the US has claimed a 12-nautical mile contiguous zone in addition to its 12-nautical mile territorial sea). Where the coasts of two states are opposite or adjacent to each other, neither state is entitled to extend its contiguous zone beyond the median line.

exclusive economic zone (EEZ) - a zone beyond and adjacent to the territorial sea, in which a coastal state has sovereign rights for the purpose of exploring, exploiting, conserving, and managing natural resources and for the economic exploitation and exploration of the zone. Countries have jurisdiction over the establishment and use of artificial islands, installations, and structures; marine scientific research; and the protection and preservation of the marine environment. The outer limit of the EEZ cannot exceed 200 nautical miles from the baselines from which the breadth of the territorial sea is measured.

continental shelf - this includes the seabed and subsoil of the submarine areas that extend beyond a country's territorial sea to the outer edge of the continental margin, or to a distance of 200 nautical miles from the baselines from which the breadth of the territorial sea is measured. The continental margin includes the submerged prolongation of the landmass of the coastal state and consists of the seabed and subsoil of the shelf, the slope, and the rise. If the continental margin extends beyond 200 nautical miles from the baseline, coastal states may extend their claim to a distance of 350 nautical miles from the baseline or 100 nautical miles from the 2,500-meter isobath, which is a line connecting points of 2,500 meters in depth.

exclusive fishing zone - this term is not used in the UNCLOS, but some states have chosen not to claim an EEZ but rather to claim jurisdiction over the living resources off their coast; in such cases, the term "exclusive fishing zone" is often used; the breadth of this zone is normally the same as the EEZ or 200 nautical miles.
