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).
