Short summary

The biological carbon pump is a mechanism by which the oceans capture atmospheric carbon dioxide thanks to microscopic marine algae. Quantifying its strength and efficiency is crucial to understand the global carbon budget and be able to forecast its trends. The radioactive pair ²³⁴Th : ²³⁸U has been extensively used for that purpose. This is a global compilation of carbon-to-²³⁴Th ratios (needed to convert the ²³⁴Th fluxes to carbon fluxes) that will contribute to improve our modeling efforts.
