Fig. (3) Downcore variations of geochemical data and coccolithophore taxa and groups at ODP Site 963, plotted versus calibrated age (kyr) and showing the marine isotopic stratigraphic framework. From the left, oxygen isotopic record of Greenland ice cores [50]; benthic and planktonic oxygen isotopic records at ODP Site 963 [14, 16]; distribution patterns of F. profunda, placoliths, miscellaneous and UPZ taxa at ODP Site 963, expressed as percentage values [13-16, 39]. Light grey bands mark Stadials, white bands mark Interstadials. S26-S2 show the sequence of Stadials across the sequence. YD: Younger Dryas.
