Comment:
AGE = Deglacial age. Dates from Hillenbrand et al. (2013) and Kirshner et al. (2012) were recalibrated using an marine reservoir effect (MRE) correction of 1300 ± 70 years. Also listed are the deglacial ages (1-9) for the western Amundsen Sea Embayment (ASE) (see Table 3 in Smith et al., 2011 for details).
