Summary
Abstract: This data set contains calcium carbonate percentage data from marine sediment
cores, plus C14 dates or age models as available, and NCDC's display software.
The analyses were done for the CLIMAP project, and for numerous regional
studies. On average, the cores span 100,000 to 200,000 years, sampled at
intervals averaging 3,000 to 10,000 years. Numerous cores span only the last
deglaciation, while a few cover intervals up to 3,000,000 years. The samples
analyzed consisted of either bulk sediment, or of fine-fraction sediment
passed through either a 63 or 74 micron sieve. There is no significant
difference in analyses based on these two fine fractions, and the sieve size
is not recorded in the files. There is also little difference between fine
and total fraction analyses, but the two types are distinguished by file
extension. The data files are compressed for distribution using PKZIP, and are
in self-extracting files. To unpack the %CaCO3 ASCII data files for total
sediment, type CO3TOTAL. For the fine fraction data files, type CO3FINE. The
data files will require about 1.3 megabytes of storage when uncompressed.
Data File Comments:

Core k708-6 carb ff: turbidite between, approximately, 910-960 cm.
Core k708-1 carb: turbidite between, approximately, 750-758 cm.
