Chinese researchers have reconstructed the history of the South China Sea's sea-level shift using local corals and found that the sea level has risen by 150 mm since 1900.
中國科學(xué)家通過對南海當?shù)厣汉鬟M行研究,重建了海平面的精細變化過程,發(fā)現(xiàn)1900年以來南海海平面上升了150毫米。
The researchers analyzed the correlation mechanism between the oxygen stable isotopes of coral and sea level, sea surface salinity, sea surface temperature and rainfall of the South China Sea, and reconstructed the sea level record at an annual resolution.
研究人員綜合分析了南海濱珊瑚氧穩(wěn)定同位素(δ18O)與器測的海平面、鹽度、海溫、降雨之間的關(guān)系,確定了南海海平面與珊瑚氧穩(wěn)定同位素的統(tǒng)計關(guān)系以及控制機理,重建了年分辨率的海平面變化。
The study showed that the sea level fell by 0.73 mm per year from 1850 to 1900, and then rose by 1.31 mm per year from 1900 to 2015. The sea-level rise in the South China Sea has accelerated recently, rising by 3.75 mm per year since 1993.
研究結(jié)果顯示,在1850–1900年時段,海平面的平均下降速率為0.73毫米/年;在1900–2015年時段的上升速率為1.31毫米/年,1993年以來的上升速率為3.75毫米/年,南海海平面呈現(xiàn)加速上升趨勢。
