Correlation of HH12-940PC (a–c) with HH15-1252PC7 (d–f) for MIS 3 and MIS 2. a Benthic δ18O measured on Melonis barleeanus and Cassidulina neoteretis. b Bottom water temperatures (BWT) calculated from transfer functions of the benthic foraminiferal faunas (RMSEP is ± 1.8767 °C). c Benthic δ13C measured in M. barleeanus and C. neoteretis. d Benthic δ18O measured on Cassidulina neoteretis. e Bottom water temperatures (BWT) from measurements of Mg/Ca (estimated total of analytical and calibration errors are ± 1.03 °C and ± 1.27 °C for C. neoteretis and M. barleeanus, respectively7). f Benthic δ13C measured in C. neoteretis. Heinrich stadials H5 to H1 and stadial (S) and interstadial numbers 12–2 are indicated. Blue horizontal bars mark Heinrich stadials, grey bars mark stadials.
