The routine use of spectrophotometry on the sediment surfaces of archive halves of each section during the onboard sedimentological core description process is a great stride toward development of real-time noninvasive characterization of deep-sea sediments. Spectral reflectance data have been used so far for mineral composition studies as well as for lithostratigraphic correlation between sites (Balsam and Deaton, 1991; Balsam et al., 1997; Mix et al., 1995; Ortiz et al., 1999). Their results demonstrate that spectrophotometry can estimate CaCO3 content by using the 4.65-, 5.25-, and 5.55-µm wavelength spectrums. A detailed overview of various other noninvasive methods is given in Ortiz and Rack (1999).The purpose of this study is to test whether spectrophotometry in the visible band can be used as a tool to gather further information about grain-size variation, sorting, compaction, and porosity, which are directly linked to the sedimentation process. From remote sensing data analyses, it is known that ... : Supplement to: Wolf-Welling, Thomas C W; Cowan, Ellen A; Daniels, J; Eyles, N; Maldonado, Andrés; Pudsey, Carol J (2001): Data report: Diffuse spectral reflectance data from rise Sites 1095, 1096, and 1101 and Palmer Deep Sites 1098 and 1099 (Leg 178, western Antarctic Peninsula).
