Summary
This chapter discusses procedures to obtain sediment colour time series from digital images of split core surfaces. This method is ideally suited to obtain sub-mm-scale colour records from laminated sediments. The most essential part of data acquisition to obtain good quality images, is that sediment surfaces are scraped carefully to remove any surface irregularities. After acquisition, line scans have to be collected through all images along the stratigraphic axis. The line scan data are subsequently corrected for uneven light distribution of the light source. Various methods for light correction are described. Examples are presented to illustrate application of the techniques especially to laminated sediments, and to compare the results with those obtained from photospectrometer data and X-radiographs.
