The subbottom data were recorded on the Mudseis data acquisition system in SEG-Y format. The conversion program processSegy was used to renumber the traces as trace 1 or traces 1 and 2 for 2-channel data and fill out the SEG-Y EBCDIC reel header. Traces were renumbered because the Mudseis system begins with trace 0 instead of 1. The data were filtered with a low pass of 300 Hz and a high pass of 3000 Hz at the acquisition step along with a 48 db gain.
