Abstract

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.
