Comment:
DEPTH, sediment [m] is given in rmcd. AGE [ka BP] follows the LR04 timescale (Lisiecki and Raymo, 2005, doi:10.1029/2004PA001071). 18 samples have Mg/Ca <0.8 mmol/mol of which 6 have Mg/Ca < 0.75 mmol/mol. The samples are within a block of heavier individuals ~ 38 µg compared with ~26µg for typical samples.
