a series of shipborne and near-bottom bathymetric and magnetic data across the ultra-slow Southwest Indian Ridge (SWIR), where crustal age is constrained by magnetic anomalies, and jointly analyze comparable datasets from various mid-ocean ridges

The data used in this paper are provided in '.srf' files, which require Surfer software version 16 or higher to open. The subfigures in the directory correspond to the topography and magnetic data of each respective research area. Each subfigure is named according to the code of the area as referenced in the main text. Within each subfigure, files prefixed with 'Post' represent magnetic stripe identification point data files or magnetic profile data, with row and column information displayed in the directory. Files prefixed with 'Color Relief' contain topographic data.
