Abstract

Abstract

Past sea surface temperature(SST) and sea level change are reconstructed for the last glacial period using the U₃₇^K and δ¹⁸O.The U₃₇^K-SST was 23.3~26.9 in the Post Glacial Period and 22.2~23.8 in the last glacial period,respectively.On the average the temperature in the last glacial period is 4.7 lower than that in present tmie.The seasonal difference of temperature was from 4.5 to 7.0 in the Post Glacial Period and 7.0 to 9.0 in the last glacial period,muchh igher than that observed at the same latitudes in the Pacific Ocean.The temperature has been decreasing while the sea leave descending during the last glacial period.Sea level change is completely controlled by the alternation of cold and warm clmiate.
