  dcterms:description "SEG-Y rev 1 is considered an acceptable format as per NARA Transfer Guidance. SEG-Y rev 1 is a revision of the SEG-Y rev 0 standard that made it so that the format is not dependent on tape as the carrier and also allowing for enhanced metadata in the textual file header. The format still consists of a 3200-byte EBCDIC reel header, a 400-byte binary reel header, and trace records consisting of a 240-byte binary trace header and trace data. SEG-Y has since been revised several times (including rev 1, 2, and 2.1 between 2002 and 2023), maintaining many key features of the original specification while updating other features to account for newer storage media and advances in geophysical data recording technologies. Because SEG-Y is the industry standard for interchange of seismic data, it is not recommended to transform to another format." ;
