海南岛滨珊瑚δ18O对环境条件的响应

RESPONSE TO ENVIRONMENTAL CONDITIONS OF CORAL δ18O OF PORITES LUTEA FROM SHALAO,HAINAN ISLAND

  • 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.
