Bathymetry around Saint-Paul and Amsterdam Islands / Data compilation 2020
Bathymetry around Saint-Paul and Amsterdam Islands: the Digital Terrain Model is the result of data compilation of multibeam surveys from 1984 to 2019. Grid resolution is 150 m.
The DTM was processed as part of the French national program (EXTRAPLAC) for the delineation of the outer limit of the continental shelf beyond 200 nautical miles, and in collaboration between Ifremer and the Western Brittany University (UBO Brest).

- Statement
-
The DTM is a result of collaboration between the Ifremer Marine Geosciences unit and the scientific group of the Pluriel cruise (Brest University).
Multibeam data were controlled and processed with Ifremer software (Caraïbes and Globe).
A similar processing chain is applied to each dataset:
- 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 DTMs are merged into a unique DTM for the area. Grid resolution is 150 m.
