            <gco:CharacterString>Le produit "Natures de fond au 150 000" a été élaboré à partir des données sédimentaires recensées, numérisées et intégrées à la Base de Donnée Sédimentologique du Shom (BDSS). 
Il représente une synthèse des données issues de levés réalisés à différentes époques à l’aide de différents systèmes :
plomb suiffé acquises par le service hydrographique (de 1820 à 1950);
analyse granulométrique des sédiments prélevés par dragage, à la benne, par carottage et forage (depuis 1890) ;
imagerie acoustique SMF et sonar latéral (depuis 1985) ; 
classification des fonds à partir du traitement du signal acoustique du sondeur monofaisceau (depuis 1992) ; 
sismique réflexion (depuis 1975) ;
analyse de la morphologie à partir des données bathymétriques (depuis 1820).
Les levés ont été réalisés par le Shom, le BRGM, l’IFREMER, les Universités de Lille 1, Rouen, Caen, Brest, La Rochelle, Bordeaux I et Corte, l’IntechMer, la Station Biologique de Roscoff, le Conseil Général de la Charente-Maritime, la Direction Départementale de l’Equipement de Charente-Maritime, l’Office de l’Environnement de la Corse, et les Ports Autonomes de Bordeaux et Marseille. 
Les travaux de compilation ont été effectués sous la responsabilité du Shom.</gco:CharacterString>

                <gmd:LocalisedCharacterString locale="#EN">The product was prepared using the sediment data listed, converted and integrated in the Shom Sediment Database (BDSS). The solution provides a summary of data from the surveys completed in various eras using a range of systems: lead plummet with tallow acquired by the hydrography service (1820 - 1950); particle size analysis of sediment samples obtained by dredging, using a container, coring and bore holes (since 1890); MBES (MultiBeam EchoSounder) acoustic imaging and side sonar (since 1985); classification of seabeds by processing the acoustic signal from the single beam echosounder (since 1992); seismic reflection (since 1975); morphological analysis based on bathymetric data (since 1820). The surveys were carried out by Shom, BRGM (French Geological Survey), IFREMER, the universities of Lille 1, Rouen, Caen, Brest, La Rochelle, Bordeaux I and Corte, IntechMer, the Biological Station of Roscoff, the Conseil Général (Departmental Council) of Charente-Maritime, the Departmental Division of Equipment of Charente-Maritime, the Environment Office of Corsica, and the Independent ports of Bordeaux and Marseille. Shom oversaw the compilation of works.</gmd:LocalisedCharacterString>
