Project Deep Carbon is a Future Fellowship awarded to Adriana Dutkiewicz. The project includes postdoctoral research associate Ehsan Farahbakhsh and PhD student Faranak Dalvand. The deep-sea carbon reservoir through geological time. Despite being by far the largest carbon reservoir on Earth, deep-sea carbonate and its recycling through the Earth system are the most significant missing links in … Read more…
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…
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…
