  • The exclusive economic zone is adjacent to the territorial sea and extends to a maximum distance of 200 nautical miles calculated from the baselines. This is a space in which the coastal State do not practice its entire sovereignty but only the following rights: - sovereign rights over the water column, the bed and subsoil for the purposes of: - exploration, exploitation, conservation and management of natural resources, whether biological or not; - exploration and exploitation of the zone for economic purposes, such as the production of energy from water, currents and wind; - jurisdiction concerning the following fields: - construction and use of artificial islands, facilities and works; - marine scientific research; - protection and preservation of the marine environment. Apart from the rights and obligations of the coastal States cited above, the exclusive economic zone is a space open to the exercise by any other State of the freedoms set down in the United Nations Convention on the law of the sea (UNCLOS) (navigation, overflight, etc.), within the limits set by the Convention.

  • The regulatory part of Volume IX of rural and sea fisheries laws is defined by the decree No 2014-1608 of 26 December 2014. In particular, Article D922-16 of the appendix to the decree defines a limit related to fisheries located at 3 nautical miles from the low waterline of the continent and islands and islets which are always dry. In the particular case of Mayotte Island, in compliance with Article 61 of the prefectural decree No 2018-681 of 30 July 2018 which regulates the exercise of sea fisheries at Mayotte department, this limits is located at 3 nautical miles from the in force baselines.

  • French Ministry of Culture / DRASSM - Shom The product "Limit of preventive archeology licence fee" contains the limits for the preventive archeology licence fee (1 nautical mile) as defined in the French Heritage Code. This limit is managed by the Department of Underwater Archeological Research (DRASSM) of the Ministry of Culture. This limit, defined by the Heritage Code at 1 nautical mile from the low-water line, permits to delineate the areas where the licence fee for preventive archeology at sea is applied. The product "Limit of preventive archeology licence fee" is to use in addition to the digital product “Maritime Limits and Boundaries” of Shom (French: “Délimitations maritimes”) which represents the limits of the French maritime spaces of sovereignty or jurisdiction through the World. The product “Maritime Limits and Boundaries” (French: “Délimitations maritimes”) can be viewed and downloaded on the French national portal of maritime limits (https://maritimelimits.gouv.fr).

  • Compilation of marine gravity surveys acquired in the Northeast Atlantic by Shom between 2001 and 2016. These surveys were compiled to perform a quantification of the error of the gravity anomaly models derived from satellite altimetry. This dataset represents more than 22,000 measurement points distributed in 9 ascii survey files sampled at 1 kilometer. The file’s format is as follows: longitude latitude Gravity_anomaly error line_label.

  • In the absence of a maritime boundary agreement with a neighbouring State, the French Republic can unilateraly claim a delimitation. This boundary has indeed a provisional aspect pending the ratification of a boundary agreement. The theme "Maritime limits unilaterally claimed" gathers those limits unilaterally claimed by France. Some of those elkements are published by decree.

  • The combined error grid of the SIO V31 gravity anomaly model (D. T. Sandwell, H. Harper, B. Tozer et al., Gravity field recovery from geodetic altimeter missions, Advances in Space Research, https://doi.org/10.1016/j.asr.2019.09.011) is computed with a method described in a paper submitted to Earth and Space Science (AGU). The model’s extension is North Atlantic.

  • In compliance with Article 33 of UNCLOS, the outer limit of the contiguous zone is located at 24 nautical miles from the baselines. The objects of the theme "Outer limit of the contiguous zone" result from Shom computations and are compliant with Article 10 of the French Order No 2016-1687 of 8 December 2016.

  • The contiguous zone is adjacent to the territorial sea and may not extend beyond 24 nautical miles from the baselines from which the breadth of the territorial sea is measured. The coastal State may exercise the control necessary to: - prevent infringement of its customs, fiscal, immigration or sanitary laws and regulations within its territory or territorial sea; - punish infringement of the above laws and regulations committed within its territory or territorial sea.

  • In the Law of the Sea, a straight baseline is composed by a loxodrome connecting two points of the low-water line or low-tide elevations if there is a lighthouse or similar permanent infrastructure on them. The conditions to draw such lines are defined in Article 7 of UNCLOS. The straight baselines are part of the baselines of a coastal State below which the internal waters are defined. Those straight baselines, in addition with the normal baseline, compose the inner limit of the territorial sea and are the basis of the computations of the outer limits of other maritime spaces defined by UNCLOS. They are also composed of the closure line for bays and rivers in compliance with Aricles 9 and 10 of UNCLOS. The objects of the theme "Straight baselines" result from Shom computations and are published by decree of the French Republic.

  • French Ministry of Agriculture and Food / DRASSM - Shom<br /> The product "Limits related to fishery uses" contains the limits related to fishery uses as defined in the French or European legislations. Those limits are managed by the Directorate for Sea Fisheries and Aquaculture (DPMA) of the Ministry of Agriculture and Food. <br /> Those limits are divided into three categories : <br /> - the inner limit of the coastal waters (6 nautical miles) ; <br /> - the 3-nautical-mile limit ; <br /> - the limit of fisheries for overseas territories (100 nautical miles).<br /><br /> The product "Limits related to fishery uses" is to use in addition to the digital product “Maritime Limits and Boundaries” of Shom (French: “Délimitations maritimes”) which represents the limits of the French maritime spaces of sovereignty or jurisdiction through the World.<br /> The product “Maritime Limits and Boundaries” (French: “Délimitations maritimes”) can be viewed on data.shom.fr (Maritime boundaries Category) and downloaded on the French national portal of maritime limits (https://maritimelimits.gouv.fr).
