(Figure 3c) Sea surface temperature reconstruction based on planktonic foraminifera sampled in surface sediments


To reconstruct sea surface temperature (SST), 27 taxonomic categories of the planktonic foraminifera census data were used with the modern analog technique SIMMAX 28 (Pflaumann et al., 1996, doi:10.1029/95PA01743; 2003, doi:10.1029/2002PA000774). To the 26 taxonomic groups widely used and listed in Kucera et al. (2005, doi:10.1016/j.quascirev.2004.07.014), Turborotalita humilis was added in our calibration as it is associated with the PCC source region (Meggers et al., 2002, doi:10.1016/S0967-0645(02)00103-0). The modern analog file is based on the Iberian margin database (Salgueiro et al., 2008, doi:10.1016/j.marmicro.2007.09.003) combined with the North Atlantic surface samples used by the MARGO project (Kucera et al., 2005). This results in a total of 1020 analogs for SST. Modern SSTs for 10 m water depth were taken from the World Ocean Atlas 1998. The residuals give the differences between SSTs of the World Ocean Atlas and foraminiferal SSTs.
