Comment:
High-resolution G. ruber d18O data covering 114.5-121.46 mcd (MIS 95-101) are published in Bolton et al. (2010, doi:10.1029/2010PA001951). High-resolution G. ruber Mg/Ca data covering 114.5-121.46 mcd (MIS 95-101) are published in Friedrich et al. (2013, doi:10.1002/palo.20029). Globigerinoides ruber Mg/Ca and d18O data from 121.46- 133.76 mcd (MIS 101-G11) are new in this study, except for 20 cm-resolution data previously published in Friedrich et al. (2013 doi:10.1002/palo.20029). Where replicate measurements of foramaminiferal Mg/Ca and d18O from the same samples were performed in both laboratories to check for offsets (See Figure 3), mean values are given here. No signifiant inter-lab offset were found.
