Box14155-6135, Tehran, Iran Journal Article 2014 10 13 The δ18O, δ13C, and strontium/calcium (Sr/Ca)-record was measured from a 7-year old Platygyra<br />sinensis coral located offshore Larak Island in the Persian Gulf at a resolution of 22 samples/year. An increased<br />sampling resolution of 55 samples/year over two annual cycles was also compared with the 22 sample<br />resolution to evaluate the effectiveness of the sampling procedure. The resulting data exhibited identical<br />results between the two methods. By means of previously reported equations, Sr/Ca-derived sea surface<br />temperatures (SST) ranged between 17 to 30 °C, with an average of 24.7 °C. The inter-annual variability in the<br />Platygyra sinensis indicated a significant correlation with COADS data. In addition, the relation between the<br />δ18O in Platygyra sinensis coral and the Sr/Ca-estimated SST data was assessed. Subtracting the Sr/Ca-based<br />SST values from the δ18O of the coral, the δ18O of water was calculated. These data were then used to construct<br />ranges of sea surface salinity (SSS) in the region. https://ijer.ut.ac.ir/article_807_f1a3ab6bb72a826d79b5e24270f870c9.pdf
