NAME OF DATA SET: ODP Site 677 timescale calibration 
LAST UPDATE: 8/96 (Original receipt date by NOAA/ WDC-A Paleo) 
GEOGRAPHIC REGION: Eastern Tropical Pacific
ODP 677A 1 deg 12.138' N 83 deg 44' W water depth 3472.3 m
ODP 677B 1 deg 13.006' N 83 deg 43.392' W water depth 3446.8 m

DESCRIPTION:
ODP Site 677 timescale calibration  notes:
Ages are by astronomical correlation.
Agemodel for 677 27.04.89
The O-18 data are species-corrected.
There was a minor analytical problem with one series of runs 
which necessitated a 0.2 per mil adjustment.
These analyses are marked with a Y in the second column.
The depths are adjusted for A-hole to B-hole differences
according to a different scheme to that in the Leg 111 volume.
Size fraction: medium
