DEPTH, sediment/rock gives meters below seafloor [mbsf]. 14C dates are uncorrected for reservoir age and from Bond et al. (1993). The date at 55 cm is from Elliot et al. (1998), and does not include a reported error; we assumed a value of 100 years. Marine09 calibration is from (Reimer et al., 2009). The reported calibration ages are the rounded, median probability determined by the online version of Calib 6.0 (Stuiver and Reimer, 1993).
