Short summary

The marine cycle of calcium carbonate (CaCO₃) influences the distribution of CO₂ between atmosphere and ocean, and thereby climate. We constrain export of biogenic CaCO₃ (globally: 0.72–1.05 Gt C yr⁻¹) and dissolution within the water column (~ 80 %) in a novel Monte Carlo set-up with the Bern3D model based on alkalinity data. Whether CaCO₃ dissolves in the upper ocean remains unresolved. We recommend using constant (saturation-independent) dissolution rates in Earth system models.
