Stable oxygen isotope ratios of planktonic foraminifera (Appendix A), supplement to: Billups, Katharina; Lindley, Carolyn; Fisler, J; Martin, Pamela (2006): Mid Pleistocene climate instability in the subtropical northwestern Atlantic. Global and Planetary Change, 54(3-4), 251-262
We present Globigerinoides ruber, G. sacculifer and Neogloboquadrina dutertrei oxygen isotope records from northwestern subtropical Atlantic Site 1058 spanning the mid Pleistocene (~600 to 400 ka). The high temporal resolution of these records (~800 yr) allows us to compare millennial-scale climate...
