The global carbon cycle box model BICYCLE is enhanced by a process-based sediment module and the consequences from prescribed fluxes of volcanic outgassing, carbonate and silicate weathering, and coral reef growth on the carbon cycle as a whole and on atmospheric CO2 in detail for the last 800 kyr are analysed. The scenarios for prescribing the fluxes are taken from the literature. Other carbon cycle processes within the ocean and terrestrial biosphere are taken as previously considered in a study published as Köhler et al. (2010, doi:10.1029/2008PA001703).
