Figure 1 Fig. 1. (A) Downcore carbonate (% of CaCO3) and {delta}18O in N. pachyderma (s) (Nps) and G. bulloides (Gb) are plotted as a function of depth (cm) in core HU91045-94 retrieved at 3448 m water depth from the Orphan Knoll, southern Labrador Sea. Downward arrows denote calibrated 14C AMS dates [data from (7, 8)], and {delta}18O and {delta}13C data in Gb are not available beyond 82 cm. (B) Carbonate (% of CaCO3), {delta}18O and {delta}13C in Nps and Gb are plotted versus depth (cm) from core MD95-2024 [see (7) for details]. Note difference in x axes in core MD95-2024 compared with HU91045-94. [View Larger Version of this Image (30K GIF file)]
