摘要

摘要: 应用U₃₇^K和δ¹⁸O重建末次盛冰期以来海水古温度和海平面变化,U₃₇^K-SST沉积记录表现了冰期/间冰期模式.U₃₇^K-SST在冰后期23.3~26.9℃;末次盛冰期22.2~23.8℃.末次盛冰期时古温度比目前平均低4.7℃,南海北部季节性温差冰后期在4.5~7.0℃;末次盛冰期在7.0~9.0℃,远远超过同一纬度太平洋季节温差.末次冰期以来在气候降温的同时,伴有海平面下降,气候的冷暖交替对海平面变化具有决定性的控制意义.

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.
