Cores TWC04 and PC04 (Gibb et al., 2014) were modeled indi- vidually then spliced at 8.3 cal ka BP for the composite CC04 sequence (Table 2, Figure 2). Olivier Cartapanis record number 3197 and 3198

ice flow influenced the records from 7-10ka (Vinther et al., 2009); No temperature calibration has been published : Vinther2009 use only Agassiz and Renland for temperature reconstruction: Johnsen 2001 use only GRIP, NGRIP, GISP2 and Dye3, with borehole temperature calibration, but suggest the use of d18O=0.67*T-13.7‰, the spatial slope.

reliable as temperature proxy back to 7 ka, before that, ice flow is dominating the signal

only safe to use as a T proxy for _-7kaBP, before that, ice flow is dominating the signal.
