Abstract

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.

Dataset

Statement

2020 : A similar processing flow is applied to each dataset, using EMODnet Bathymetry project methodology :

- Selection of relevant profiles for acoustic coverage of the study area

- Automatic and manual filtering of outliers and erroneous data

- Control of overlapping zones

- Production of a digital terrain model. Depth layer is calculated as the average of soundings in each pixel.

All DTM are merged into a unique DTM for the area.

Multibeam data were controlled and processed with Ifremer softwares (Caraïbes and Globe).

The dataset covering International and French waters is cut by SHOM maritime boundaries and VLIZ maritime boundaries v.11 https://doi.org/10.14284/382

2025 : adding data from the following cruises : BICOSE 3, HERMINE2, MANTA-RAY, TV_HORPTP 2022, TV_PTPBES 2023 et MANTA-RAY 2.
