peer reviewed Sea ice is an active source or a sink for carbon dioxide (CO2), although to what extent is not clear. Here, we analyze CO2 dynamics within sea ice using a one-dimensional halo-thermodynamic sea ice model including gas physics and carbon biogeochemistry. The ice-ocean fluxes and vertical transport of total dissolved inorganic carbon (DIC) and total alkalinity (TA) are represented using fluid transport equations.
