Comment:
Corrected ages adjusted using the lake reservoir effect determined for a core-top sample. Calibrated ages were calculated with OxCal 4.1 and the IntCal09 calibration curve (Bonk Ramsey, 2009; Reimer et al., 2009). Radiocarbon results regarded as outliers are marked with an asterisk on the laboratory ID number. For age calibration a value of -30 per mil for the d13C of TOC was used.
