Bathymetry - Area covered during transits of the French research vessels

This dataset contains, as polygon features, the areas covered by the bathymetric Digital Terrain Models (DTM), from value added transits of the French oceanographic fleet. The data acquisition is carried out in an opportunity mode during the ship's transit. Acoustic data are acquired by deep-sea multibeam echosounder (12kHz), in an opportunity mode, during the ship transits. All DTM have a 1 / 8 arcminute grid spacing, Transits are described by the DOI : https://doi.org/10.18142/337 The DTMs can be accessed via the geographical view of this dataset, or directly below in the related resources.
