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