(Table 1) Age determination of sediment core SONK_11_D

资源简介：
Sediment depth is given in composite depth (mcd). Conventional 14C ages were calibrated using OxCal 4.1 (Ramsey, 1995, 2001, 2009) with the IntCal09 calibration data set (Reimer et al., 2009). Conventional 14C ages obtained from aquatic material and bulk sediment OM were corrected by -150 years before calibration to consider the hardwater effect. Samples down to 0.215 mcd were not considered for age modeling.
