Chemical and physical measurements in coral tanks from Moorea, French Polynesia in 2010 (OA Corals project)

<p>Two laboratory experiments were completed using Porites lutea and Montipora aequituberculata from back and fringing reef habitats. First, in Moorea, French Polynesia, we evaluated the efficacy of linear extension as a dependent variable characterizing the response of corals in competitive encounters, as well as a means to test for an effect of elevated pCO2 on linear extension. Second, at Sesoko Island, Okinawa, we applied the techniques developed in Moorea to test the effects of elevated pCO2 on the ability of corals to compete with one another for space.</p>

<p>Temperature, pH, pCO2, total alkalinity, and the aragonite saturation state (omega) were measured daily in the tanks.</p>

<p>本研究依托采自礁后与岸礁生境的澄黄滨珊瑚（Porites lutea）与结节微孔珊瑚（Montipora aequituberculata），完成了两项室内受控实验。其一，在法属波利尼西亚莫雷阿岛，我们评估了将线性生长速率作为表征珊瑚竞争互作响应的因变量的有效性，同时以此检验升高的二氧化碳分压（pCO₂）对珊瑚线性生长的影响；其二，在冲绳濑底岛，我们运用在莫雷阿岛建立的实验方法，探究升高的pCO₂对珊瑚争夺空间的竞争能力的影响。</p>

<p>实验养殖体系内的水温、pH值、pCO₂、总碱度以及文石饱和状态（Ω）每日均进行测定。</p>
