Bathymetry - Lesser Antilles volcanic arc (synthesis, 2025)

Bathymetry of the Lesser Antilles volcanic arc, at a spatial resolution of 1/16 arc minute. This Digital Terrain Model is a compilation of multibeam echosounders data. Restriction : the DTM largely overlaps national EEZ. The entire product cannot be freely disseminated. Processing : Since the beginning of the 1990s, the scientific exploration of the West Indian arc has provided the opportunity for regular acquisition of multibeam bathymetry. About twenty scientific cruises and valued transits feed a remarkable database and offer a wide bathymetric coverage of this geological structure. They were assembled to produce a bathymetric model of the entire region. The final product is a double dataset : a raster at 1/16 minute steps (~ 100 m) of bathymetric data, and a shapefile that identify data sources. Processing report : "Talbot Sophie (2019).
