Global contribution of echinoderms to the marine carbon cycle: CaCO 3 budget and benthic compartments
The contribution of carbonate‐producing benthic organisms to the global marine carbon budget has been overlooked, the prevailing view being that calcium carbonate (CaCO 3 ) is predominantly produced and exported by marine plankton in the “biological pump.” Here, we provide the first estimation of th...

The contribution of carbonate‐producing benthic organisms to the global marine carbon budget has been overlooked, the prevailing view being that calcium carbonate (CaCO 3 ) is predominantly produced and exported by marine plankton in the “biological pump.” Here, we provide the first estimation of the global contribution of echinoderms to the marine inorganic and organic carbon cycle, based on organism‐level measurements from species of the five echinoderm classes. Echinoderms' global CaCO 3 contribution amounts to ~0.861 Pg CaCO 3 /yr (0.102 Pg C/yr of inorganic carbon) as a production rate, and ~2.11 Pg CaCO 3 (0.25 Pg C of inorganic carbon) as a standing stock from the shelves, slopes, and abyssal depths. Echinoderm inorganic carbon production (0.102 Pg C/yr) is less than the global pelagic production (0.4–1.8 Pg C/yr) and similar to the estimates for carbonate shelves globally (0.024–0.120 Pg C/yr).
