Indian Ocean carbonate compensation depth since the Late Oligocene

by

The carbonate compensation depth (CCD), defined as the depth in the ocean where the supply rate of pelagic carbonate is balanced by its dissolution, provides an important parameter for estimating the amount of calcium carbonate-bound carbon that is stored in deep-sea sediments. The CCD is reasonably well-constrained across the Atlantic and Pacific oceans; however, our … Read more…

Regional Carbonate Compensation Depth variability in the Pacific Ocean since the Oligocene

by

Deep-sea carbonates constitute the primary deep carbon reservoir, playing a critical role in regulating the long-term global carbon cycle. Reconstructing the temporal evolution of carbonate flux to the seafloor requires estimating the changes in carbonate compensation depth (CCD), a key proxy, revealing the depth where the rate of calcium carbonate supply from biogenic ooze equals … Read more…
