[2013]; (2) this study.For radiocarbon dating the surface-dwelling planktic foraminifera species Globigerinoides ruber in a strict sense and Globigerinoides sacculifer (without the sac-like final chamber) were handpicked under a binocular microscope from the >150 µm fraction. The abundance of these species within the cores was generally low, and occasionally, both species were combined to obtain a sufficient amount of datable material. Samples were then measured at the Keck Carbon Cycle Accelerator Mass Spectrometry Laboratory, University of California, Irvine. Raw 14C ages were converted to 2Sigma calendar ages with the CALIB 7.0 software using the Marine13 calibration data set [Reimer et al., 2013] (Table 1) with a regional reservoir correction of 100 years [Southon et al., 2013].
