We have generated a quantitatively valid dissolution index                 for modern sediments in the west-equatorial Pacific, which is                   tied to carbonate saturation values.  We wish to apply this                     index to a series of long cores, taken across the lysocline on                  the slope of Ontong-Java Plateau, in order to reconstruct the                   saturation history of deep waters in this region, for the last                  450 kyr.  The time scale will be provided by a fit of oxygen                    isotope stratigraphy to the Imbrie et al.  (1984) standard.                     Absolute rates of dissolution will be derived from comparison                   of synchronous instantaneous accumulation rates of cores from                   above and below the lysocline, checked against dissolution                      indices.  In conjunction with data on the isotopic compositions                 of benthic foraminifera, the calibrated saturation curves will                  allow determination of probable pCO2 of deep waters, and                        provide useful contraints on the reconstruction of the late                     Pleistocene carbon chemistry and circulation.  Our focus is on                  the contrast between middle and late Brunhes time, and on that                  between the extreme states (glacial-interglacial) and the                       extreme rates of change (glacierization-deglaciation).
