Sea surface temperature (SST) is one o~ the most important parameters in marine environment. During the Quaternary glacial/interglacial periods, environmental changes have been evidenced by SST reconstruction, which is significant to understand the evolution of global climate change, and has at- tracted so many studies since the 1950's. From thepaleonto function TEXss , dogical in s, stable dex spec isotopes, es to faunal transfer Mg/Ca ratio, U/k 37 and SST reconstructions experienced a process from qualitative, semi-quantitative to quantitative.
