Abstract:

We were unable to locate a data table so the data were extracted from Figure 4a in Zahn et al. (1991). The figure was scanned and data optically resolved into an age-CaCO3% data set to 728 ka. Ages were established by Zahn et al. (1991) by correlation to oxygen isotope profiles.

Keyword(s):

biogenic silica; Mass accumulation rates; Ocean Drilling
