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 S189500800 (http://dx.doi.org/10.17183/S189500800). // Instruments: Plomb de sonde // Number of soundings: 9141 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. Les données proviennent de la campagne S189500800 (http://dx.doi.org/10.17183/S189500800). // Instruments: Plomb de sonde // Nombre de sondes: 9141 Shom +33 (0)2 56.31.23.12 +33 (0)2 56.31.25.80 13, rue du Chatellier CS92803 BREST CEDEX 2 29228 France bps@shom.fr http://www.shom.fr/ custodian asNeeded https://services.data.shom.fr/static/imagettes/LEVES_BATHY_AVANT_1970_PACK_DL/S189500800.png thumbnail png Bathymetry and Elevation Bathymétrie et altitude parameter SeaDataNet Parameter Discovery Vocabulary P02 2022-05-04 revision 120 http://www.seadatanet.org/urnurl/SDN:P02 plummets plomb de sonde instrument SeaDataNet device categories L05 2021-06-15 revision 81 http://www.seadatanet.org/urnurl/SDN:L05 research vessel navire océanographique platform_class SeaVoX Platform Categories L06 2021-03-25 revision 17 http://www.seadatanet.org/urnurl/SDN:L06 Bathymetric Dataset are available under Open License (version 2.0 - April 2017), Etalab mission Les levés bathymétriques sont diffusés sous Licence ouverte (version 2.0 d'avril 2017), définie par la mission Etalab Quote the source as follows: "Shom, bathymetric dataset.
