French maritime areas
This theme brings together information on maritime delimitations: straight baselines ; outer limits of the territorial sea (12 nautical miles) ; outer limits of the contiguous zone (24 nautical miles) ; outer limits of the exclusive economic zone (200 nautical miles), limits resulting from agreements with neighbouring States and French maritime spaces governed by the United Nations Convention on the Law of the Sea.
This page is the reference medium for the State's communication on maritime spaces under French sovereignty or jurisdiction.
