Additional Documentation: PROCESSED BY GEOLOGICAL DATA CENTER-SIO FOR OCEAN DRILLING PROJECT. ORIGINAL RECORDS ARCHIVED AT ODP, NAVIGATION ON/OFF SITE TIMES MAY BE INACCURATE DUE TO INSUFFICIENT SHIP, SPEED DATA. 1 MINUTE GPS FIXES ARE USED ON THE SURVEY BEFORE AND AFTER, SITES. THIS RESULTS IN LINEAR INTERPOLATION BETWEEN ONE MINUTE FIXES FOR, SITE POSITIONS.
