Abstract

Data on colony growth of the branching coral Acropora palmata from fringing reefs off Discovery Bay on the north coast of Jamaica have been obtained over the period 2002-2007 using underwater photography and image analysis by both SCUBA and remotely using an ROV incorporating twin lasers. Growth modelling shows that while logarithmic growth is an approximate model for growth, a 3:3 rational polynomial function provides a significantly better fit to growth data for this coral species. Over the period 2002-2007, involving several cycles of sea surface temperature (SST) change, the rate of growth of A. palmata was largely proportional to rate of change of SST, with R(2)=0.935. These results have implications for the influence of global warming and climate change on coral reef ecosystems.

摘要

2002年至2007年期间，通过水下摄影和图像分析，利用水肺潜水以及使用配备双激光的遥控水下机器人（ROV）进行远程操作，获取了牙买加北海岸发现湾沿岸礁脉上分支珊瑚鹿角珊瑚的群体生长数据。生长模型表明，虽然对数生长是生长的近似模型，但一个3:3有理多项式函数能更显著地拟合该珊瑚物种的生长数据。在2002年至2007年期间，经历了几个海面温度（SST）变化周期，鹿角珊瑚的生长速率在很大程度上与SST的变化速率成正比，相关系数R(2)=0.935。这些结果对全球变暖和气候变化对珊瑚礁生态系统的影响具有启示意义。
