ABSTRACT
Simulations with a coupled ocean-atmosphere-sea ice model are used to investigate the role of wind-driven sea ice motion on ocean ventilation. Two model experiments are analyzed in detail: one including and the other excluding wind-driven sea ice transport. Model-simulated concentrations of chlorofluorocarbons (CFCs) are compared with observations from the Weddell Sea, the southeastern Pacific, and the North Atlantic. The authors show that the buoyancy fluxes associated with sea ice divergence control the sites and rates of deep- and intermediate-water formation in the Southern Ocean. Divergence of sea ice along the ...
