NAME OF DATA SET: Core MD900963 Calcium Carbonate & Stable Isotopes
LAST UPDATE: 10/95 (Original Receipt by WDCA Paleo)  
GEOGRAPHIC REGION: Indian Ocean
PERIOD OF RECORD: 0 - 1500 KYRBP
LIST OF FILES: MD900963.txt, MD900963.readme.

DESCRIPTION:
The file is an ASCII formated file that contains:
- depth (m) - first column contains the "corrected" depths. A slump has
been eliminated in the calculation of these sub-bottom depths;
- depth (m) - second column contains the "un-corrected" depths;
- d18O (%o)
- d13C (%o)
- > 63 µm (%) - obtained by sieving sediments for extraction of foraminifers;
- relative abundance of foraminifer fragments (%) (dissolution index)
- carbonate content in the bulk sediment (%)

The core MD900963 has been retrieved in the Indian Ocean, east of the
Maldives platform (5°03.30N-73°52.60E) from a water depth of 2446 m during
the MD65-SEYMAMA expedition of the R/V Marion Dufresne that took place in
1990 (Y. Lancelot, chief scientist).

* Sedimentological analysis have been performed at the Laboratoire de
Geologie du Quaternaire, CNRS Case 907, 13288 Marseille, France
* Stable isotopes composition have been obtained on the planktonic species
G. ruber picked in the 250-355 µm size fraction. Measurements have been
done with a  Finnigan MAT 251 at the Centre des Faibles Radioactivites,
CNRS/CEA, Domaine du CNRS, 91198 Gif-sur-Yvette, France

There is no age column in the MD900963 data file.  An age model has been
developed in the paper: Bassinot et al., EPSL, 126 (1994), 91-108. 
This age model might be slightly modified in the future and the
"final" age model, when it is available, will be included with the data.
