Summary
Abstract: We explore using changes in planktonic foraminiferal Mg/Ca with water depth in
a single region to infer relative changes in deep water carbonate chemistry.
The Mg/Ca ratio in foraminiferal calcite is quantitatively lowered by
dissolution. We exploit this dissolution effect to generate a profile of
carbonate ion concentration (CO3 2-) for the deep waters of the tropical
Atlantic during the Last ... View entire text
