Bathymetry of the French Guiana margin and Demerara Plateau / Data compilation 2019
Bathymetry of the French Guiana margin: the digital terrain model results from data compilation of 3 multibeam surveys conducted on the French research vessel RV L’Atalante. Grid resolution is 250 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.

- Dataset
- Statement
-
Multibeam data were controlled and processed with Ifremer software (Caraïbes and Globe).
A similar processing flow 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 250 m.
