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.

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 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 theme "Agreed maritime boundaries" contains the delineation limits between maritime spaces under sovereignty or jurisdiction of France et neighbouring States which are established by ratification of a boundary agreement or by a decision of an arbitral tribunal or an international legal body entitled to deal with cases relating to the Law of the Sea.

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).

Limits defining ship classes based on their assigned operating maritime zones. These limits were produced by CEREMA in application of section II.14 of article 1 of decree no. 200945 amended on 30 August 1984. Navigation categories are defined in article 223.2 of the rules appended to the order of 23 November 1987 on shipping safety.

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.

<strong>This data is not up to date with the order dated 30 August 2021 amending the order dated 23 November 1987 on ship safety, which now raises the limit for category 4 ships to 5 miles from the nearest coast.</strong> The navigation category allocated to a ship is indicated on its shipping license, together with any applicable restrictions. This limit was produced by Shom in application of section II.14 of article 1 of decree no. 84-810 amended on 30 August 1984. Navigation categories are defined in article 110.10 of the rules appended to the order of 23 November 1987 on shipping safety.
