Spectral reflectance provides a rapid, high-resolution, noninvasive tool for characterization of downcore mineralogical variations in deep-sea sediments. This can be demonstrated by comparison of the percent reflectance data with shipboard carbonate measurements (fig. 9, Shipboard Scientific Party, 1996b). On board the JOIDES Resolution, sediment reflectance measurements were used as an aid in identifying lithologic unit boundaries and for assistance in developing composite, spliced records at each site. Reflectance provided the primary criteria for splice determination at Site 982, which lacked a strong lithogenic signal. The processed reflectance data described in this report are included in the Table of Contents ASCII FILES for scientific use.
