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, TV_TRANSIT_BATHY

Ensemble résultant du découpage par zones du chenal de navigation.Ces passes sont régulièrement hydrographiées.

The update of the coastal topo-bathymetric DEM of the Gironde estuary - downstream with a resolution of 0.0002° (~ 20 m) was carried out in the third phase of the HOMONIM project. This DEM covers the downstream part of the Gironde estuary, from Pauillac to its mouth. It is complementary to the DEM covering the upstream estuary. The DEM is intended to be implemented in hydrodynamic models in order to produce forecasts as accurate as possible of water heights and sea states at the coast to improve the relevance of the Wave-Submergence Vigilance. This product is available with either the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical reference.

The update of the coastal topo-bathymetric DEM of the Gironde estuary - upstream with a resolution of 0.0002° (~ 20 m) was carried out in the third phase of the HOMONIM project. This DEM covers the upstream part of the Gironde estuary, from Pauillac to Bordeaux on the Garonne and to Libourne on the Dordogne. It is complementary to the DEM covering the downstream estuary (between Pauillac and the mouth of the Gironde). The DEM is intended to be implemented in hydrodynamic models in order to produce forecasts as accurate as possible of water heights and sea states at the coast to improve the relevance of the Wave-Submergence Vigilance.
