The most significant record contained in most surface coral skeletons are the annual density bands [1]. The bands are primary skeletal characteristics that consist of high and low density portion per year discernible by x-ray of a thin slab cut along the axis upward of corallite growth [2] [3]. Annual variations in density represent changes in both the rate of linear skeletal extension and calcification [1].
The bands can be used for to establish chronologies and to identify stress events [1].
