Tiepoints used to place the cores DSDP 594, MD88-770, MD02-2488, MD84-551, ODP site 1094, SO136-003, PS1768-8, PS2102-2 and MD97-2120 onto the LR04 benthic stack chronology. The δ18O data for each core is correlated to the LR04 benthic stack (Lisiecki & Raymo 2005) using the Analyseries software (Paillard et al. 1996). LR04 ages are presented against depth in the core with the exceptions of cores DSDP 594, MD88-770 and SO136-003 where the LR04 age is presented against the "age" published in Barrows et al. (2007). The MIS stage boundaries use the LR04 ages from Lisiecki & Raymo (2005) and the MIS 5 sub-stage boundaries use the ages from Govin et al. (2009). Benthic δ18O data is used for the correlation of cores DSDP 594 (Nelson et al. 1993), MD88-770 (Labeyrie et al. 1996) and MD02-2488 (Govin et al. 2009) to the LR04 benthic stack. Planktic δ18O data is used for the correlation of cores MD84-551 (Pichon et al. 1992), ODP site 1094 (Kanfoush et al. 2002), SO136-003 (Barrows et al. 2007), PS1768-8 (Mulitza et al. 1999), PS2102-2 (Niebler 1995) and MD97-2120 (Pahnke et al. 2003) to the LR04 benthic stack.
