MV1316 MCS data Jayne Bormann and Graham Kent provided the SEG-Y and rp location files in UTM coordinates (zone 11, WGS 84). They provided 3 data sets. stacked and migrated MCS - Data doi: 10.1594/IEDA/500032. Processed by SIO. No navigation in the original headers. UTIG seimic data center converted the rp navigation to latitude/longitude in arc seconds and placed that in the headers at bytes 73-76, 77-80. velocity files - Data doi: 10.1594/IEDA/500033. Processed by Geotrace for SIO. UTM navigation is in the headers of the original SEG-Y files. This was extracted, converted to latitude/ longitude, and placed in ASCII navigation files (*.ploc). The SEG-Y files were renamed to conform to the data center's file-naming system and archived unaltered. migrated files - Data doi: 10.1594/IEDA/500034. Processed by Geotrace for SIO. UTM navigation is in the headers of the original SEG-Y files. This was extracted, converted to latitude/ longitude, and placed in ASCII navigation files (*.ploc). The SEG-Y files were renamed to conform to the data center's file-naming system and archived unaltered.
