    In:  Supplement to: Broecker, Wallace S (2008): A need to improve reconstructions of the fluctuations in the calcite compensation depth over the course of the Cenozoic. Paleoceanography, 23(1), PA1204, https://doi.org/10.1029/2007PA001456
    Publication Date: 2020-01-17
    Description: Reconstructions based on back-tracked depths of the transition between CaCO3-bearing and CaCO3-depleted sediment suggest that over the last 65 million years the ocean's CaCO3 compensation depth (CCD) has remained within the range 4.0 ± 0.6 km. Taken at face value, these results indicate that depth of the calcite saturation horizon and hence also the product of the Ca2+ and [CO3]2- concentrations have remained nearly constant. In turn, this suggests that the ratio of calcite production to ingredient supply has not undergone large changes. In this paper, the method used to reconstruct the temporal fluctuations and interocean differences in the depth of the calcite saturation horizon is scrutinized. The basis for my concern is that offset between the depth of the calcite saturation horizon and the depth where dissolution reduces the CaCO3 content to 20% (i.e., the CCD) can vary by a half kilometer or so depending on the rain rates of CaCO3 and non CaCO3. When observations on modern ocean sediments are used to test the reliability of these reconstructions, the result is that when averaged over a full glacial cycle, the depth of the CCDs in the Pacific and Indian oceans fall within the long-term range. Reliable documentation of fluctuations around this long-term average requires that additional measurements, such as extent of fragmentation, be used to supplement those of CaCO3 content.

    In:  Supplement to: Broecker, Wallace S; Clark, Elizabeth (1999): CaCO3 size distribution: A paleocarbonate ion proxy? Paleoceanography, 14(5), 596-604, https://doi.org/10.1029/1999PA900016
    Publication Date: 2020-01-17
    Description: Lysocline reconstructions play an important role in scenarios purporting to explain the lowered atmospheric CO2 content of glacial time. These reconstructions are based on indicators such as the CaCO3 content, the percent of coarse fraction, the ratio of fragments to whole foraminifera shells, the ratio of solution-susceptible to solution-resistant species, and the ratio of coarse to fine CaCO3. All assume that changes with time in the composition of the input material do not bias the result. However, as the composition of the input material does depend on climate, none of these indicators provides an absolute measure of the extent of dissolution. In this paper we evaluate the reliability of the ratio of 〉63 µm CaCO3 to total CaCO3 as a dissolution indicator. We present here results that suggest that in today's tropics this ratio appears to be determined solely by CO3= ion concentration and water depth (i.e., the saturation state of bottom waters). This finding offers the possibility that the size fraction index can be used to reconstruct CO3= ion concentrations for the late Quaternary ocean to an accuracy of ±5 µmol/kg.
