The influence of ocean flow on newly forming sea ice
[1] The heat and mass balance of the Arctic Ocean is very sensitive to the growth and decay of sea ice and the interaction between the heat and salt fields in the oceanic boundary layer. The hydraulic roughne ss of sea ice controls the detailed natur e of turbulent fluxe s in the boundar y layer and...
