Abstract

Bathymetry around the Kerguelen Islands: the Digital Terrain Model results from the data compilation of multibeam surveys from 1998 to 2011. Grid resolution is 200 m.

The DTM has been 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 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 200 m.
