摘要

摘要: 应用烯酮化合物的不饱和比值U₃₇^k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U₃₇^k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 U₃₇^K 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 U₃₇^K is close to the above value.
