AB Mg/Ca measurements have been performed on tests from the planktonic foraminifers Globigerinoidesruber (white) and Globigerina bulloides in samples from ODP site 977A in the Alboran Sea (WesternMediterranean) in order to estimate their calcification temperatures between 250 and 190 ka and therefore,analyse the evolution of different water masses in the Alboran Sea during that time. The results obtainedare similar to the sea surface temperatures estimated by other methods in previous studies carried out inthe same core. All substages in marine isotope stage 7 are well defined in the paleotemperature estimates,excepting substage 7.2 which is not recognized in Globigerina bulloides. Warm substages were characterizedby strong seasonality and thermal stratification of the water column. By contrast, less pronounced seasonalityand basin stratification seem to have prevailed during cold substages
