Figure 3. TEX₈₆–sea surface temperature (SST) (this study), selected stable oxygen and carbon isotopes of planktic foram-inifera (foram.) species Hedbergella aff. H. trocoidea (Ocean Drilling Program Site 1049, from Erbacher et al., 2001). Sea surface salinity (SSS) estimates based on selected ¹⁸O of H. aff. H. trocoidea and TEX₈₆ using the model of Railsback et al. (1989; see text for discussion).
