Independent sea surface temperature (SST) estimates obtained using planktonic foraminiferal transfer functions and the Mg/Ca ratios show excellent agreement, with r2 correlation coefficients of –. Planktonic foraminiferal assemblages are similar, through time, across several deep basins, suggesting that major changes must have occurred in near synchroneity across the Aegean Sea. | Late Quaternary paleoceanographic evolution of the Aegean Sea: planktonic foraminifera and stable isotopes
