Bathymetry and backscatter grids along the axis of the Mid-Atlantic Ridge south of the Romanche transform fault (0° 02' 30"N - 0° 20' 56"S)
Gridded shipboard multibeam bathymetry and backscatter mosaics along the axis of the Mid-Atlantic Ridge. The used data are part of the dataset acquired during the SMARTIES cruise (2019). The gridded datasets cover different portions of the axis of the Mid-Atlantic Ridge south of the Romanche transform fault.
