摘要

摘要: 利用采自海南岛东岸沙老岸礁的活体橙黄滨珊瑚岩心,测试了其中11 a (1992-2002)的珊瑚骨骼氧同位素组成。通过与同期观测记录的海洋表面温度、海洋表层盐度进行比较分析,提出珊瑚δ¹⁸O对环境条件变化的响应特征。该地区珊瑚δ¹⁸O的年际变化主要受海洋表面温度的控制,而以夏季为代表的季节性变化则主要受海洋表层盐度的影响。

Abstract: Based on the determination of the oxygen isotopic analysis of the skeleton of living Porites lutea in Shalao fringing reef, Hainan Island, we obtained a coral δ¹⁸O record for an 11 year period(1992-2002). We have assessed the characteristics of coral δ¹⁸O signals responding to environmental conditions by comparing coral δ¹⁸O variation with a local record of sea surface temperature (SST) and sea surface salinity (SSS), respectively. We conclude from our comparison that the annual variation of δ¹⁸O is controlled by SST, whereas the seasonal variation of it by SSS.
