Title V of Volume IX of rural and sea fisheries laws defines the measures related to Overseas territories. Articles R951-14 and R953-5 in particular define for specific Overseas territories a limit located at 100 nautical miles from the in force baselines. Inside this limit, fisheries are limited to the ships registered in the ports of those Overseas territories, except dispensation allowed by State. Those restrictions are not applied to ships registered in the European Union which are traditionally fishing in those waters, as long as they do not exceed the fisheries effort which is traditionally applied.

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.

In the Law of the Sea, the continental shelf located beyond 200 nautical miles affects the seabed and its subsoil on which the coastal State exerts sovereign rights for purposes of exploration and exploitation of its natural ressources. In those areas, the wealth generated by the exploitation of the natural ressources are shared via the International Seabed Authority between the States which have signed UNCLOS (in particular with the developping States or the ones which do not have access to the sea). The outer limit of the continental shelf beyond 200 nautical miles is determined in compliance with the criterias of Article 76 of UNCLOS and notably by the examination of a submission deposited by the Coastal State to the Commission for the Limits of the Continental Shelf (CLCS). the outer limit of the French continental shelf beyond 200 nautical miles is the final result of the national program EXTRAPLAC after the adoption of recommandations by CLCS, the delineation of the attributed areas with neighbouring States if necessary and the publication by decree. The theme "Outer limit of the continental shelf beyond 200 nautical miles" gathers the limits of the extended continental shelf which has been recommended by CLCS and published by a decree of the French Republic.

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 compliance with Article 57 of UNCLOS, the outer limit of the exclusive economic zone (EEZ) is located at 24 nautical miles from the baselines. This limit distinguishes the EEZ from the High Sea. Beyond this limit, an extension of the continental shelf is possible subject to the criterias of Article 76 of UNCLOS. The objects of the theme "Outer limit of the exclusive economic zone" result from Shom computations and are compliant with Article 10 of the French Order No 2016-1687 of 8 December 2016. They are published by decree of the French Republic.

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).

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.

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).

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.
