(Appendix 1) Census data of planktic foraminiferal faunas together with estimates of mean annual SST for sediment core R657

Depth is composite depth (mcd), age after the Lisiecki and Ramyo (2005) stack (datasets: doi:10.1594/PANGAEA.704257). ODP 1125 data consists of 167 census counts compiled for the last 1 myr (MIS 28-1; 5-10 kyr resolution). These comprise 15 faunas from adjacent piston core R657 (MIS 5-1) studied by Weaver et al. (1998, datasets: doi:10.1594/PANGAEA.691461) and 152 faunas from between 21.5 and 1.6 mcd (MIS 27-6; 5-10 kyr resolution) studied by Schaefer et al. (2005, datasets: doi:10.1594/PANGAEA.691478). The base of the SST record from R657 was spliced to the ODP 1125 record at the MIS 6-5 boundary, using the carbonate, reflectance, fragmentation index and SST records (Weaver et al., 1998; Schaefer et al., 2005).
