Shipboard color reflectance data contain some unresolved problems; however, most data can be used with caution. Shipboard color reflectance data from Site 1119 are not usable. The carbonate prediction model fit is good at Sites 1120, 1121, 1124, and 1125 (shipboard data) and Holes 1119C and 1123A (laboratory data). Models for Sites 1122 and 1123 (excluding the model from laboratory data) are of questionable usefulness but are included for comparison and completeness.
