| Summary: | During the past year research efforts have been concentrated in the following general areas: (1) theoretical modeling of the dynamics and thermodynamics of sea ice, with particular emphasis on the role of young ice, (2) optical properties of sea ice and their effects on ocean/atmosphere energy exchange, (3) desalination and entrainment processes in both growing and melting ice, and (4) ablation of horizontal, vertical and sloping ice walls by sea water near the freezing point. Scientific results of laboratory and theoretical studies on the interaction of petroleum with sea ice, the disalination of young ice, the drag on moving pressure ridge keels due to the formation of internal waves near the pycnocline, the spectral distribution of short-wave radiation in the ocean beneath the first year sea ice, the dependence of heat exchange over young sea ice on its thickness, and the thickness distribution of sea ice in the Central Arctic have been written up and are now either in print or in press. Other papers describing the optical properties of sea ice, the melting of fresh ice by warm sea water, the observed generation of internal waves in the Arctic Ocean by pressure ridge keels, and the evolution of pressure ridge keels during the summer melt season are in preparation. |
