AbstractStrontium concentrations in modem Porites coral from XishaIslands were determined by precise thermal ionization mass spectrometry. The coral skeleton grew in the period from 1976 to 1994. The results indicate that the variability of coral Sr is periodically at annual cycles, and is in agreement with in situ measured sea surface temperature (SST). The calibration of Sr and SST with correlation coefficient r = -0. 94 has been developed at monthly sampling resolution. In addition, maximum and minimum seasonal monthly Sr and SST values were also regressed for the 18-year interval, and the correlation coefficient is -0. 98. The error of this Sr thermometer is better than 0. 5 ℃.
西沙群島現代濱珊瑚1976～1994年生長期間Sr含量的高精度熱電離質譜測定結果表明，Sr含量隨季節發生周期性的變化，并與當地同期實測海水月平均溫度變化相吻合，其Sr含量與實測海水溫度相關系數為-0.94。這18年冬夏季極端Sr含量與同期月溫的相關系數可高達-0.98。Sr溫度計誤差小于0.5℃。
