We propose a method to reconstruct temperature gradients between various depths in the water column, but most specifically between 30 m and 250 m, using the d18Ocalcite composition of foraminiferal calcite. Changes in past sea-surface water stratification in the temperate southern South Atlantic Ocean and in the Antarctic Circumpolar Current can be reconstructed in particular with G. bulloides, G. truncatulinoides and G. inflata. Modern temperature gradients between 30 m and 250 m water depth are reconstructed accurately within a range between 1.7 and 9.4 °C with a correlation coefficient of 0.77 and a standard deviation of ±1.3 °C.
