Notes: Mass accumulation rates (MARs) are averaged over 100-k.y. intervals. Carbonate compensation depth (CCD) estimates in plain text are one-site estimates assuming 0.001 g/cm2/k.y. loss of CaCO3 per additional meter of water depth. CCD estimates in bold text are estimates using both Sites 1218 and 1219. CCD estimates in italics are extrapolations of the CCD assuming a decrease of roughly 0.001 g CaCO3/cm2/k.y. per additional meter of water depth near the CCD.
