(Table 1) AMS radiocarbon analyses of bulk TOC and carbonate material from sediment core GeoB18308-1

Depending on sediment type (terrestrial or marine identified via BIT-Index) the Southern Hemisphere calibration curve (SHCal13) (Hogg et al., 2013) or the modelled ocean average curve (Marine13) (Reimer et al., 2013) were used. To the later a DeltaR of 146 ± 85 14C (Dewar et al. 2012) was applied.
