Summary: We determined oxygen isotope ratios (δ18O) of the mixed layer- dwelling planktonic foraminifer Globigerina bulloides and relative abundance of Neogloboquadrina pachyderma (sinistral) for the last glacial-interglacial cycle, including marine isotope Stage (MIS) 6 from Integrated Ocean Drilling Program Site U1313. The δ18O data in G. bulloides allowed us to construct an age model. Changes in relative abundance of N. pachyderma (s) were compared to the δ18O of G. bulloides. We also performed a detailed quantitative study of four planktonic foraminiferal species to assess surface to near-surface oceanographic changes for the period between MIS 5e and 6 (120-180 ka), including the penultimate glacial termination (TII). Analyses of the relative abundances of four planktonic foraminiferal species lead us to reconstruct the variability in the upper water masses of the North Atlantic at this subtropical site. We found clear indications of freshwater inputs, including a Heinrich iceberg-rafting event (H11), which provided a mechanism for freshening the sea surface and perturbing climate conditions.
