For depth up to 50m, the vertical precision of soundings varies from 30cm to 1m and the horizontal precision varies from 1 to 20m. In deep ocean, the vertical precision is mainly around 1 or 2% of the bottom depth. It is sometimes more, it depends on the technology used. The data are referenced to ZH which is assimilated to LAT. Data are corrected for sound velocity variations. Data are acquired during the campaign S198703000 (http://dx.doi.org/10.17183/S198703000). // Instruments: Sondeur DESO 10 | Sondeur DESO 20 | Profondimètre // Number of soundings: 10985 Les levés bathymétriques sont des semis de sondes issus de levés provenant de la base des données diffusables par le Shom. Pour les fonds jusqu à 50m, la précision verticale des sondes varie de 30cm à 1m et la précision planimétrique de 1 à 20m. Au-delà, dans les grands fonds, la précision verticale est majoritairement de l ordre de 1 à 2% de la profondeur du fond. Parfois, elle est plus élevée selon la technologie utilisée. Les données sont référencées au ZH qui est assimilé à la Plus Basse Mer Astronomique (PBMA). Les données sont corrigées des variations de la célérité du son dans l eau.
