Gridded bathymetric data along the ultraslow spreading Southwest Indian Ridge between the Gallieni TF and the Rodrigues triple Junction

Six large grids were obtained by merging multibeam bathymetric data from several international cruises along the Southwest Indian Ridge from the Gallieni Transform Fault (54°E) to the Rodrigues Triple Junction (70°E). The spatial resolution is about 150 m. This dataset was used in several scientific papers.
