• Description:
  The 13C/12C of dissolved inorganic carbon ( δ13CDIC) carries valuable information on ocean biological C-cycling, air-sea CO 2 exchange, and circulation. Paleo-reconstructions of oceanic 13C from sediment cores provide key insights into past as changes in these three drivers. As a step toward full inclusion of 13C in the next generation of Earth system models, we implemented 13C-cycling in a 1° lateral resolution ocean-ice-biogeochemistry Geophysical Fluid Dynamics Laboratory (GFDL) model driven by Common Ocean Reference Experiment perpetual year forcing. The model improved the mean of modern δ13CDIC over coarser resolution GFDL-model implementations, capturing the Southern Ocean decline
