Comment:
Mean calibrated ages were used to construct the age models. The online version of the program CALIB 7.1 was used, with access dates of 12 November 2016 (GeoB16601-5; samples 17-18 and 35-36) and 11 December 2017 (MD05-2905; all samples). The online version of the program CALIBomb was used for the GeoB16601-5 core top (0-1 cm), with access date of 28 January 2019. For core 16601-5: Radiocarbon concentrations are given as fractions of the modern standard, D14C, and conventional radiocarbon age, following the conventions of Stuiver and Polach (1977). Sample preparation backgrounds have been subtracted, based on measurements of 14C-free calcite. All results have been corrected for isotopic fractionation according to the conventions of Stuiver and Polach (1977), with d13C values measured on prepared graphite using the AMS spectrometer. These can differ from d13C of the original material, if fractionation occurred during sample graphitization or the AMS measurement, and are not shown.
AMS- radiocarbon ages of core MD05-2905 were originally published by Yang et al. (2008; Frontiers of Earth Science in China 2: 170-176) and re-calibrated to improve the age model of this core.
