Figure 13. Downcore profiles of Ca2+ and Mg2+ at Site 1087 (solid lines with open circles). Profiles from Sites 1085 and 1086 (dotted lines) are shown for comparison. Shaded region = depth interval of elevated dissolved Ca2+ concentrations. Arrows = mean ocean-bottom-water values taken from Millero and Sohn (1992).
