Table 2 Radiocarbon ages of core PS-92/045. The dates were obtained on the planktonic foraminifera Neogloboquadrina pachyderma. Depth at which N. pachyderma foraminifera were collected are documented by using the unit cmbsf (centimeters below seafloor). Radiocarbon dates were adjusted to account for a 400-year reservoir effect and calibrated using CalPal Online Radiocarbon Calibration of 14C (http://www.calpal-online.de/)95,96. The calibrated ages have 1σ uncertainty.
