Appendix 2: Summary of Digital Data from G1-03-GM
This appendix gives tables of the tapes, CD's and DVD's created on G1-03-GM. The official archive for metadata related to this cruise, including navigation, is at the Western Coastal and Marine Geology Team of the USGS in Menlo Park, California, in the InfoBank archive. The SEG-Y files of the stacked MCS data will be released in an Open-File Report and available for download from the following web-site after USGS review and approval: http://walrus.wr.usgs.gov/reports. Copies of all CD's were taken separately to the Menlo Park, CA and Woods Hole, MA USGS offices.
