Bathymetric dataset S188000400

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 ZH which is assimilated to LAT. Data are corrected for sound velocity variations. Data are acquired during the campaign S188000400 ( http://dx.doi.org/10.17183/S188000400). // Instruments: Plomb de sonde // Number of soundings: 3891

Statement: 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.
