Carbonate chemistry parameters in flume study during the day from Richard B Gump Research Station - Moorea LTER, French Polynesia from 2013 (MCR LTER project, OA_Corals project)

<p>To investigate the response of coral reef communities to OA, we used large outdoor flumes in which communities composed of calcified algae, corals, and sediment were combined to match the percentage cover of benthic communities in the shallow back reef of Moorea, French Polynesia. Reef communities in the flumes were exposed to ambient (400 μatm) and high pCO2 (1300 μatm) for 8 weeks, and calcification 10 rates measured for the constructed communities including the sediments. Community calcification was depressed 59% under high pCO2, with sediment dissolution explaining 50% of this decrease; net calcification of corals and calcified algae remained positive, but was reduced 29% under elevated pCO2.</p>

<p>为探究珊瑚礁群落对海洋酸化（Ocean Acidification, OA）的响应，本研究采用大型户外流水槽（flume），将由钙化藻类、珊瑚与沉积物构成的群落按比例组合，以匹配法属波利尼西亚茉莉雅岛浅海礁后区的底栖生物覆盖占比。流水槽内的礁群分别暴露于环境水平（400 μatm）与高二氧化碳分压（pCO2，1300 μatm）条件下，持续8周；并对包含沉积物在内的构建群落测定了钙化速率。高二氧化碳分压条件下，群落总钙化率降低了59%，其中沉积物溶解可解释该降幅的50%；珊瑚与钙化藻类的净钙化率仍为正值，但在高pCO2下降低了29%。</p><p><strong>相关参考文献：</strong><br />Comeau, S.、Carpenter, R.
