| 摘 要： | 应用烯酮化合物的不饱和比值U37k计算得出冲绳海槽海水古温度波动幅度在15.9～26.2℃之间,平均为22.9℃,和冬季实测表层水温22.0℃相接近,探讨了U37k值在冲绳海槽指示的古海水温度和季节有关,主要反映在冬季。

| Abstract: | The sea surface temperature is estimated by the U37K value (the unsaturated ratio of alkenone) in sediment from the Okinawa Trough during the last 20000 a.They range from 15.9 to 96.2℃,the average is 22.9℃.The sea surface temperature in winter is 22℃.It indicates that the sea surface temperature from U37K is close to the above value. |
