携带pH和O2电极和热敏电阻的仪器包漂浮在礁石上。利用与碱度异常技术相关的方程，并通过某些假设，计算了礁滩的生产率和钙化率。在800 μ E [微爱因斯坦]的平均光强度下。m-2.cntdot. s-1时，平均净O2产量为21.5 mmol O2·cm-1。m-2.cntdot. h ~（-1），平均钙化率为11.0mmol CaCO_3·cm ~（-1）。m-2.cntdot. h-1。结果表明，3个代谢带内的样带，对应于在航空照片中看到的地带性和底栖生物调查证实。
An instrument package carrying pH and O2 electrodes and a thermister was floated across a reef flat. Using equations associated with the alkalinity anomaly technique, and by making certain assumptions, the producitivity and calcification rates of the reef flat were calculated. At an average light intensity of 800 .mu.E [microeinstein] .cntdot. m-2 .cntdot. s-1, the average net O2 production was 21.5 mmol O2 .cntdot. m-2 .cntdot. h-1 and the average rate of calcification was 11.0 mmol CaCO3 .cntdot. m-2 .cntdot. h-1. Results showed 3 metabolic zones within the transect which corresponded to zonation seen in an aerial photograph and confirmed by benthic surveys.
