Comment:
DEPTH, sediment/rock gives meters below seafloor [mbsf]. The tie points to GISP2 used to produce the age model for Site 609 are shown at left (Bond et al., 1999). These data are presented graphically in Fig. 3 of Bond et al. (1999) but are not presented in table format as above. At right are our ties of the same depths in Site 609 to the NGRIP ice core. A 705-year shift to younger ages is required to align GICC05 and GICC05modelext time scales at 60 ka (Svensson et al., 2008). GISP2 depth 2465.9807: Based on the MS/94 age model for GISP2, which assigned ages of 53.22 ka and 53.5 ka to 2464 mand 2466 m, respectively, a tie point to a depth of exactly 2465.98071428571 m in GISP2 is required to obtain the age of 53.4973 ka that was assigned by Bond et al. (1999) to 347.5 cm in Site 609.
