Simulations of glacial climate and ocean biogeochemistry with the CSIRO Mk3L v1.0 P. Buchanan https://doi.org/10.4225/41/5859eeac6b473

Short summary

We quantify the contributions of physical and biogeochemical changes in the ocean to enhancing ocean carbon storage at the Last Glacial Maximum. We find that simulated circulation and surface conditions cannot explain changes in carbon storage or other major biogeochemical fields that existed during the glacial climate. Key modifications to the functioning of the biological pump are therefore required to explain the glacial climate and improve model–proxy agreement for all fields.
