q 2002 American Meteorological Society On the Role of Wind-Driven Sea Ice Motion on Ocean Ventilation
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 chlorofl...
