Wefer, Geology 28 , 927 (2000). 7. Even this massive geological carbon-cycle perturbation is dwarfed by anthropogenic rates of carbon emissions [~0.2 gigatons (Gt) per year for PETM and 8 Gt per year for modern ( 30 )]. 8. The CCD is the depth at which the rate of calcite input from surface waters equals the rate of dissolution and, in practice, is mapped on the sea floor by the transition from carbonate-bearing (above the CCD) to carbonate- free (below the CCD) sediments. 9.
