Figure F2. A. Reflectance vs. carbonate analyzed by coulometer method. ODP = Ocean Drilling Program. URI = University of Rhode Island. B. Median grain size diameter and opal vs. carbonate; linear regressions are -0.0787 x CaCO3 = 9.2824 (R2 = 0.83) and -0.0391 x CaCO3 + 4.5917 (R2 = 0.62), respectively. C. Bulk sediment
