AB Planktonic foraminifer assemblages from core PRGL1-4 have been studied to reconstruct sea surfacetemperatures (SST) in the Gulf of Lions during Marine Isotope Stages 6 and 7 based on the modern analogtechnique. This method consists of a comparison between core and modern sample assemblages assumingthat similar planktonic foraminifer assemblages develop under the same ecological conditions and thatforaminifer ecological preferences have not changed in time. During stage 6 (glacial) a strong millennialvariability is observed in SST, whereas in stage 7 (interglacial) the astronomical forcing controls SST. Thesefeatures have been already reported in temperature records from other areas out of the MediterraneanSea, which means that SST in the Gulf of Lions during stages 6 and 7 was influenced by global climatechanges. Moreover, some differences exist between paleotemperature records from different areas in theMediterranean region. In the Gulf of Lions temperature records are more extreme since this area is directlyinfluenced by Mistral and Tramontane winds, which cause important water cooling during cold periods.Furthermore, this study suggests that seasonality in the Gulf of Lions is not influenced by NorthernHemisphere summer insolation
