The definitive coastal information system, Quadrige stores coastal observation and monitoring network data. In order to manage coastal monitoring data, Ifremer developed the Quadrige² information system. Quadrige is one element of the Water Information System (SIE) http:// www.eaufrance.fr, et à ce titre, contribue aux travaux du Secrétariat d'Administration National des Données Relatives à l'Eau (SANDRE) http://www.sandre.eaufrance.fr. Quadrige Marine Zones is a reference source unique to the Quadrige system. It is used to break down the coast of the French mainland and overseas territories into large areas and to connect each one with observation and monitoring locations.

DTM data source was received from the data center (Bathymetrisches Datenzentrum) of the German Hydrographic Office (Bundesamt für Seeschifffahrt und Hydrographie) at a variable resolution. The data was then processed by ATLIS b.v. using the ATLIS SENS software suite and compiled into an EMODnet regional DTM. Although the resolution varied throughout the dataset, no interpolation was required to create a geographic grid of 0.0041667 degrees resolution.

Les périmètres des quartiers prioritaires de la politique de la ville sont fixés par le décret n° 2014-1750 du 30 décembre 2014 pour la métropole et par le décret n° 2014-1751 du 30 décembre 2014 pour les départements et collectivités d’outre-mer, rectifiés par le décret n°2015-1138 du 14 septembre 2015.

The regional bathymetric Atlantic – Channel – North-Sea DTM has a resolution of 0.001° (~111m). Its geographic coverage includes the Bay of Biscay, the English Channel and a part of the North Sea. The DTM extends from the coast to the continental slope (about of 4800m deep). This DTM is produced in the framework of the HOMONIM project which aims at improving operational forecast capabilities for the national coastal flood warning system. This DTM is offered openly on the Shom diffusion website (http://diffusion.shom.fr/produits/bathymetrie/mnt-facade-atl-homonim.html). http://dx.doi.org/10.17183/MNT_ATL100m_HOMONIM_WGS84

The “World Seabed Sediment Map” product contains geo-referenced digital data, describing the nature of the sediment encountered in different seas and oceans of the world. The objects are all surface areas and the description of an object includes in particular the nature of the sediment including rock-type bottoms.

Geomorphologic map at 1 : 500 000 of the French metropolitan EEZ produced in the work-package 4 (sea-floor geology / geomorphology) of the European project EMODnet Geology. This version of the dataset corresponds to the phase IV of the project.

This marine multibeam and sampling survey was undertaken on Stanton Banks by the Joint Nature Conservation Committee (JNCC), Centre for Environment, Fisheries & Aquaculture Science (CEFAS) and British Geological Survey (BGS) in July/August 2012 on board the Northern Lighthouse Board vessel NLV Polestar. The survey was led by the JNCC and included a team from CEFAS who were involved in benthic sampling. A combination of surveys methods were employed, including seabed imagery (drop camera), day grabs and rock dredges. BGS collected sea floor multibeam bathymetry data using a Kongsberg EM3002D multibeam system.

Geomorphological analysis of the continental slope of the Mediterranean sea, based on a 100 m Data Terrain Model (DTM). This DTM is a synthesis of data acquired during several surveys. Bibliographic references :
