Bathymetric datasets are an extraction of surveys belonging to the Shom public database. 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 057 France - Sein (ile) Nord (ZH) which is assimilated to LAT. Data are corrected for sound velocity variations. Data are acquired during the campaign S197501500 (http://dx.doi.org/10.17183/S197501500). // Instruments: Sondeur DESO 10, Sondeur lateral // Number of soundings: 1976 // DOI: http://dx.doi.org/10.17183/LOTS_BATHY#S197501500-001

Bathymetric datasets, collected after 2005, are controlled and qualified by the Shom. They are mainly acquired with multi-beam echosounders. Ask the data centre for details.

Bathymetric datasets, collected before 1970, are historical surveys acquired with leadlines (and single-beam echosounders after 1930-1940). Quality controls and qualification, conducted by the Shom, on these datasets are not exhaustive. Datasets may present significant uncertainties and errors may remain. Ask the data centre for details.
