1Territorial waters or a territorial sea as defined by the 1982 UNCLOS, is a belt of coastal waters extending at most 12 nautical miles (22.2 km; 13.8 mi) from the baseline (usually the mean low-water mark) of a coastal state.
2archipelagic waters are the waters enclosed by the archipelagic baselines as drawn in accordance with section 6; "conservation and management" includes all methods and measures which are: (a) Required to rebuild, restore or maintain, or which are useful in rebuilding, restoring or maintaining any (UNCLOS 1982).
