Abstract:
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 (https://maps.ngdc.noaa.gov/viewers/bathymetry), Japan Agency for Marine-Earth Science and Technology (http://www.godac.jamstec.go.jp/darwin/e), and the German Datacenter for bathymetric data (https://www.bsh.de/EN/DATA/Oceanographic_Data_Center/Surveying_data/surveying_data_node). Data were processed and gridded using Multibeam System (https://www.mbari.org/products/research-software/mb-system) and can be displayed using Generic Mapping Tools (https://gmt.soest.hawaii.edu). 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.
