a, TEX86 Bayspar-derived SST for middle and low (orange) and high (blue) latitudes datasets with corresponding 90% confidence interval. b, Comparison between δ15N-gradient (Δδ15NP-A) and latitudinal SST-gradient (ΔSSTL-H) calculations, using two SST calibrations: SSTBayspar after Tierney and Tingley138 (with the propagated 90% confidence interval from a) and SSTTEXH after Kim et al.137. c Latitudinal TEX86-gradient (ΔTEX86 L-H) in comparison with the latitudinal SST gradient proposed by Cramwinckel et al.99. (ΔT = SSTTEXH86 − SSTδ18O, black line). Note that ΔTEX86 L-H does not depend on the calibration used.
