珊瑚骨骼中递增条带的研究由Ma 1发起，后来由Wells 2和其他人3扩展。最近，离散的年度带状在某些造礁珊瑚的骨骼4，5，6已被描述。在这里，我们提出了一个年度带宽测量百慕大珊瑚的相关分析，通过回归技术，珊瑚带时间序列的空气温度和气压变化。我们的研究结果表明，珊瑚带记录其环境的重要方面，因此成为有用的古气候变量重建的兴趣。具体而言，珊瑚的时间序列可以用作古温度指标，或与相对完善的古温度相结合，用于古压力测定。由此导出的一系列以其他方式无法获得的古变量不仅对珊瑚生理学的研究很重要，而且对气候模型的构建和测试也很重要;在后一种情况下，有关古压力的信息尤其重要。
STUDY of incremental banding in coral skeletons was initiated by Ma1 and later extended by Wells2 and others3. More recently, discrete annual banding in the skeletons of certain hermatypic corals4,5,6 has been described. Here we present an analysis of annual band width measurements from Bermuda corals which relates, through regression techniques, coral band time series to air temperature and air pressure variations. Our results indicate that coral bands record important aspects of their environment and therefore become useful where reconstruction of palaeoclimatic variables is of interest. Specifically the coral time series may be used as a palaeotemperature indicator or, when coupled with relatively well established palaeotemperatures, for palaeobarometric pressure determinations. Derived series of otherwise unobtainable palaeovariables are important not only for work on coral physiology, but also for construction and testing of climatic models; in this later instance information on palaeopressure is particularly desirable.
