1- The sovereignty of the coastal state extends beyond its land territory and internal waters or its archipelagic waters if it is an archipelagic state, to a maritime zone adjacent known as the territorial sea.
2- This sovereignty extends to the airspace above the territorial sea as well as to the seabed and subsoil beneath it.
3- The exercise of sovereignty over the territorial sea is subject to the provisions of this Agreement and other rules of international law.
Each state has the right to determine the breadth of its territorial sea at a distance not exceeding 12 nautical miles measured from the baseline established in accordance with this Agreement.
The outer limit of the territorial sea is the line that is at every point on it a distance from the nearest point on the baseline equal to the breadth of the territorial sea.
Except in cases where this Agreement provides otherwise, the normal baseline for measuring the breadth of the territorial sea is the low-water line along the coast as shown on officially recognized large-scale maps by the coastal state.
