Fig. 3

Image example of an axial CT acquisition of a sediment core, showing the coordinate system referred to as the CT scanner coordinate system in the manuscript and illustrating the line search to determine size and position of the scanned object on axial images. Three points a, b, and c are determined by a bisection algorithm along the search direction. Note the distribution of coral fragments in the core and the gap between sediment and core liner at the top of the image
