a Mg/Ca-SST of G. ruber; b Mg/Ca-subT of N. dutertrei; c the vertical temperature difference between SST and subT (ΔTG-N); d G. ruber Mg/Ca-SST of cores MD97-2125 (ref. 27) (pink) and MD06-3018 (ref. 28) (red); e δ18Osw records of G. ruber of MD97-212527 (sky blue) and MD06-301828 (blue); f surface δ18Osw record from G. ruber; g subsurface δ18Osw record from N. dutertrei; h the salinity difference between subsurface and surface water (ΔSN-G); shaded blue bars indicate glacial intervals and dashed gray curves indicate polynomial fitting of glacial–interglacial cycles; i spectral analysis of SST and subT of core KX97322-4; j spectral analysis of SSS and subS; dashed curves represent the 95% confidence level. Shaded bars represent the 100-kyr and 23-kyr signals. All data are shown in Supplementary Data 1.
