NAME OF DATA SET: MD952042 Oxygen and Carbon Isotope Data

LAST UPDATE: 6/2002: Correction to age model. 
The control point with age 72.89 ka in the GISP part of the age 
model changed to 68.72ka.
Three of the data files plus the age model file are affected:
the planktonic mean dataset, the benthic mean dataset, and the 
"P. wuell only" c13 file.  File names for these are:
md952042-agemodel.txt, md952042-meanplank.txt, md952042-meanbenth.txt,  
and md952042-mean13c.txt.
