利用珊瑚生长率重建西沙海域罗马暖期中期海温变化
Sea Surface Temperature Variations during the Middle Rome Warm Period as Reconstructed by Poritescoralgrowth Rates in the Xisha Islands
摘要
Abstract
The skeletal growth rates of Porites corals are important indicators of ambient sea surface temperatures (SST). Three Porites corals collected from Yongxing Island, Xisha Islands, dated to 120-59 BC, 46 BC-14 AD and 30 BC-28 AD respectively, were analyzed for skeletal growth rates to reconstruct the local SST variations in the Rome Warm Period. The mean values of their growth rates were 0.88 cm/a, 0.90 cm/a and 1.12 cm/a, ranging from 0.53-1.24 cm/a, 0.58-1.53 cm/a, and 0.71-1.46 cm/a, respectively. The reconstructed average annual SST were 26.7℃, 26.8℃ and 27.3℃ respectively. The average SST in the Xisha Islands was 26.93±0.41℃ during the Rome Warm Period (120-59BC,46BC-28AD), 0.7℃ lower than the mean temperature recored from 1981 to 2010 AD.关键词
