AB Samples from core ODP site 977, retrieved in the Alboran Sea (Western Mediterranean Sea), havebeen studied in order to better constrain the factors controlling the Sr/Ca ratio in planktonic foraminifers.For this purpose, this ratio has been measured in two different species, Neogloboquadrina pachyderma(right coiling) and Globigerina bulloides, in samples from the marine isotope stage 7 (250-190 kyr). Thefast and pronounced fluctuations in shell Sr/Ca observed between substages cannot only respond to watersalinity, pH nor temperature changes. However, the results obtained suggest that shell Sr/Ca variations inplanktonic foraminifers from the Alboran Sea are also related to Sr/Ca glacial/interglacial changes in theocean. This would mean that the paleotemperature reconstructions based on corals, might be revisedsince coral Sr paleothermometry would have underestimated sea surface temperature during glacialepisodes
