Bathymetric data from oceanic transform faults and their associated fracture zones were compiled, providing high-resolution gridded seafloor topography. Data used in this compilation were open and archived at US American National Oceanographic and Atmospheric Administration (, Japan Agency for Marine-Earth Science and Technology (, and the German Datacenter for bathymetric data ( Data were processed and gridded using Multibeam System ( and can be displayed using Generic Mapping Tools ( All grids are in netCDF format.
The compilation includes transform faults and fracture zones from the Northern and Southern East Pacific Rise, the Cosos-Nazca spreading center, Chile Rise and the Pacific Antarctic Ridge, the Southwest Indian Ridge, Central Indian Ridge and Southeast Indian Ridge as well as the Mid-Atlantic Ridge.
