NAME OF DATA SET: Late Quaternary Southern Ocean Carbon Cycling Data Set
LAST UPDATE: 7/2004 (Correction of carbonate values for core E49-18 in file hp94_dissdata.csv)   
GEOGRAPHIC REGION: Southern Oceans
PERIOD OF RECORD: 0-500KYrBP

LIST OF FILES: 
Macintosh Excel 3.0 files contained in the Stuffit
Archive file HP94_data.sit, comma-delimited ASCII files as follows:
HP92_Coreloc.csv: Core locations
HP92_Agemodels.csv: Stratigraphic tie points used to develop 
age models in the paper
HP94_Codes.csv: Codes for dissolution data
HP94_Dissdata.csv: Dissolution-related data (file replaced 7/12/2004 to correct 
                   CaCO3 values for core E49-18 only)
HP94_Pres_index.csv: Composite Preservation Index and Stacked del18O
from the same cores
 
DESCRIPTION:
Data tables from the original reference, which demonstrates enhanced 
carbonate dissolution during glacial stages in the southern ocean,
which implies changes in deep ocean circulation.
