Law of the Sea

Who owns the ocean? Maritime zones, navigation rights, and disputes over the world's most contested waters.

Maritime Zones

The United Nations Convention on the Law of the Sea (UNCLOS, 1982) — often called the 'constitution for the oceans' — divides the sea into zones measured from a state's coastline (the 'baseline'):

  • Territorial sea (0-12 nautical miles): Full sovereignty. Foreign ships have a right of 'innocent passage' — they can transit but cannot engage in activities like fishing or espionage.
  • Contiguous zone (12-24 nm): The state can enforce customs, immigration, and sanitary laws.
  • Exclusive Economic Zone (EEZ) (up to 200 nm): The state has sovereign rights over natural resources (fish, oil, minerals) but other states retain freedom of navigation.
  • Continental shelf (up to 350 nm in some cases): Rights over seabed resources.
  • High seas (beyond national jurisdiction): Open to all states — freedom of navigation, fishing, and scientific research.
