2009年3月期间，利用原位方法对波多黎各恩里克岛礁的新陈代谢进行了研究。利用底栖生物氧气通量，通过边界层梯度法和围隔法来计算群落净生产力。利用边界层氧气梯度和阻力系数计算出的生产力范围为-12.3至13.7毫摩尔氧气/平方米·小时。围隔法测得的生产力范围为-11.0至12.9毫摩尔氧气/平方米·小时。在研究过程中，两种方法之间每小时的平均差值为0.65毫摩尔氧气/平方米·小时（r² = 0.92），这使得边界层（-33.1毫摩尔/平方米·天）和围隔（-46.3毫摩尔/平方米·天）技术对群落净生产力的估算结果较为吻合。这些独立方法的结果证实了恩里克岛礁新陈代谢的量化速率。两种方法之间的高度一致性表明，边界层测量能够对珊瑚礁健康状况进行近实时评估。
The metabolism of Cayo Enrique Reef, Puerto Rico, was studied using in situ methods during March 2009. Benthic O2 fluxes were used to calculate net community production using both the boundary layer gradient and enclosure techniques. The boundary layer O2 gradient and the drag coefficients were used to calculate productivity ranging from −12.3 to 13.7 mmol O2 m−2 h−1. Productivity measurements from the enclosure method ranged from −11.0 to 12.9 mmol O2 m−2 h−1. During the study, the mean hourly difference between the methods was 0.65 mmol O2 m−2 h−1 (r2 = 0.92), resulting in well‐reconciled estimates of net community production between the boundary layer (−33.1 mmol m−2 d−1) and enclosure (−46.3 mmol m−2 d−1) techniques. The results of these independent approaches corroborate quantified rates of metabolism at Cayo Enrique Reef. Close agreement between methods demonstrates that boundary layer measurements can provide near real‐time assessments of coral reef health.
