Conclusions

Paleoproxy records allowed us to reconstruct changes in the upper water mass conditions in the North Atlantic from MISs 5e to 6 at subtropical Site U1313. Planktonic foraminifers were well-linked to climatic and environmental conditions in this area and serve as a paleoproxy. Changes in sea-surface conditions and ensuing water masses were reflected by changes in foraminifer relative abundances. Iceberg input was inferred by the presence of IRD. We identified Event H11 at Site U1313, which was associated with a freshwater release and ensuing perturbation of sea-surface conditions. The warmest sea-surface conditions appear in phase with interglacial MIS 5e and the coolest conditions appear in phase with glacial MIS 6.
