Navigation files for the processed PTSM SEG-Y data from the 2018 ILAB-SPARC cruise to the Chain transform fault

The data set consists of navigation data (.txt files) associated with the processed SEG-Y data for ILAB-SPARC MCS profiles ILAB-SP05 and ILAB-SP08. The columns in the text files are arranged as follows: (1) Profile name (Either ILAB-SP05 or ILAB-SP08). (2) CDP number. (3) Distance (km) (A local distance scale for each profile used for velocity model building). (4) CDP longitude (in decimal degree east). (5) CDP latitude (in decimal degree north). 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.
