Direct measurements indicate that rapid dissolution of aragonite and Mg-calcite in the central Sargasso Sea begins 1,000 m deeper (3,500 and 4,400 m, respectively) than observed carbonate dissolution depths for these two minerals. Thus, whereas the rate of dissolution appears to be controlled by the degree of saturation, the carbonate content of sediment is also related to other oceanographic parameters.
