After the slab ocean component computes the atmosphere-ocean heat fluxes and updates and , the thermodynamic sea ice model takes the latter two variables as input and computes the atmosphere-ice and ocean-ice heat fluxes and advances the state of the sea ice, including snow depth, surface temperature, ice thickness, ice fractional coverage, and internal energy profile in the ice. The physics of the sea ice component model in CAM 3.0 are discussed in detail in the next chapter.
