Processed multi-channel seismic reflection data (SEG-Y) from the 2018 ILAB-SPARC cruise to the Chain transform fault

The data set contains processed multi-channel seismic reflection profiles from the ILAB-SPARC cruise aboard R/V Pourquoi Pas? at the eastern ridge-transform intersection of the Chain transform fault in the equatorial Atlantic Ocean. The profiles sample an 80-km long transform-parallel median ridge. The processed SEG-Y files are composite post-stack time-migrated sections that image the subsurface triplication event at the eastern Chain median ridge in the equatorial Atlantic Ocean. Details about the processing steps are available in the accompanying document called ILAB_MCS_processing.pdf. The data was generated as part of the project called Imaging Lithosphere Asthenosphere Boundary–St. Paul, Romanche and Chain (ILAB-SPARC). The ILAB-SPARC cruise was funded by the European Research Council Advanced grant no. 339442 TransAtlanticILAB awarded to Dr. Satish Singh.
