Territorial seas for the Republic of the Marshall Islands (RMI). Territorial waters, or a territorial sea, as defined by the 1982 United Nations Convention on the Law of the Sea, is a belt of coastal waters extending at most twelve nautical miles (12 nmi) from the baseline (usually the mean low-water mark) of a coastal state. The territorial sea is regarded as the sovereign territory of the state, although foreign ships are allowed innocent passage through it; this sovereignty also extends to the airspace over and seabed below.
