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 Regulation (EU) No 1380/2013 of European Parliament and Council of 11 December 2013, in its second paragraph of Article 5, authorises Member States to establish coastal waters along its coasts. Those areas enable member States to restrain fisheries to specific species to specific Member States following precise rules (quotas, limited fishery season). The description of the French coastal waters is established in Part 6 of Appendix 1. The coastal waters extend from 6 nautical miles from in force baselines to 12 nautical miles from in force baselines. Only portions of the French coasts are concerned.

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.

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.

The territorial sea extends from the baselines to a maximum distance of 12 nautical miles, calculated from the baselines. The State has full sovereignty over the bed and subsoil, surface and underlying water column and air space. Sovereignty shall not, however, hinder the right of innocent passage of which the ships of all States benefit in the territorial sea.

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.

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.

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 compliance with Article 3 of UNCLOS, the outer limit of the territorial sea is located at 12 nautical miles from the baselines. It corresponds to the inner limit of the contiguous and exclusive economic zones. The objects of the theme "Outer limit of the territorial sea" result from Shom computations and are published by decree of the French Republic. Some of those limits are note published by decree yet.
