Figure 30. Downcore profiles of dissolved alkalinity, sulfate, and ammonium at Site 1081 (solid lines with open circles). Lithostratigraphic subunits shown on right-hand bar. Profiles of alkalinity at previous Leg 175 sites (dotted lines) are shown for comparison. Arrows = mean ocean-bottom-water values taken from Millero and Sohn (1992).
