Gridded geophysical shipboard data on the South Intra-Transform segment of the St. Paul transform system (COLMEIA cruise)

Gridded shipboard multibeam bathymetry and gravity datasets acquired during the COLMEIA cruise (2013). Gridded sediment thickness derived from seismic data. Gridded crustal thickness computed from gravity. The gridded datasets cover the South intra-transform segment of the St. Paul transform fault system.

Grids created with the GMT software.

Grid details as follows:
