Energy Exchange Over Antarctic Sea Ice in Late Winter

In September and October 1989 during the Winter Weddell Gyre Study energy balance measurements were performed from the Soviet ice-breaker Akademik Fedorov. The average radiation balance of the sea ice surface turned out to be zero, i.e., short-wave radiation gains were, fully compensated by long-wav...

Description
Summary:In September and October 1989 during the Winter Weddell Gyre Study energy balance measurements were performed from the Soviet ice-breaker Akademik Fedorov. The average radiation balance of the sea ice surface turned out to be zero, i.e., short-wave radiation gains were, fully compensated by long-wave radiation losses. Due to turbulent fluxes of sensible and latent heat the atmosphere received about 25 W m-2 energy from the ice/ocean system. Since no significant ice melting or freezing was observed, the latter must originate mainly from warm deep water which is entrained into the oceanic mixed layer.
