This data set includes the minimal data necessary to reproduce the findings of Nissen et al. (2022). Output of model simulations with the global ocean biogeochemical model FESOM1.4-REcoM2 is provided. In particular, besides information on the model grid, the data set includes a) physical variables such as temperature, salinity, mixed layer depth, an age tracer, and surface buoyancy fluxes and b) biogeochemical variables such as air-sea CO2 fluxes, fluxes of sinking particulate organic carbon into the deep ocean below 2000 m, and total carbon concentrations. Furthermore, this data set includes physical fluxes of total carbon, i.e., vertical and lateral advection and mixing. Depending on the variable in question, model results are provided for the period 1980-2100 for the core experiments of the paper (simA-ssp5-8.5 with varying atmospheric CO2 levels and a changing climate, the control simulation simB, and simC with varying atmospheric CO2 levels and a constant climate) and for the period 2101-2150 for two idealized extensions of experiment simA forced at the ocean surface with constant atmospheric conditions.
