 Article 10 



1. An island is a naturally-formed area of land, surrounded by 

 water, which is above water at nigh-tide. 



2. The territorial sea of an island is measured in accordance with 

 the provisions of these articles. 



Article 11 



1. A low-tide elevation is a naturaUy-formed area of land which 

 is surrounded by and above water at low-tide but submerged at high 

 tide. Where a low-tide elevation is situated wholly or partly at a 

 distance not exceeding the breadth of the territorial sea from the 

 mainland or an island, the low-water line on that elevation may be 

 used as the baseline for measuring the breadth of the territorial sea. 



2. Where a low-tide elevation is wholly situated at a distance ex- 

 ceeding the breadth of the territorial sea from the mainland or an 

 island, it has no territorial sea of its own. 



Article 12 



1. Where the coasts of two States are opposite or adjacent to each 

 other, neither of the two States is entitled, failing agreement between 

 them to the contrary, to extend its territorial sea beyond the median 

 line every point of which is equidistant from the nearest points on 

 the baselines from which the breadth of the territorial seas of each of 

 the two States is measured. The provisions of this paragraph shall 

 not apply, however, where it is necessary by reason of historic title 

 or other special circumstances to delimit the territorial seas of the 

 two States in a way which is at variance with this provision. 



2. The line of delimitation between the territorial seas of two States 

 lying opposite to each other or adjacent to each other shall be marked 

 on large-scale charts officially recognized by the coastal States. 



Article 13 



If a river flows directly into the sea, the baseline shall be a straight 

 line across the mouth of the river between points on the low-tide line 

 of its banks.
