Abstract: Large ice brocks frequently are deposited on the dry tidal flats during low tide, where they may remain for an extended period of time. The distribution of ice temperature throughout the whole ice thickness can then be assumed to be uniform and equal to the air temperature. At high water stages (high tides or wind floods), the floes will again float and be carried away by the current. The temperature versus time variation (local and mean temperature) is calculated for pure ice and for sea ice of several salinities after the floes are again floating. The exact one-dimensional heat diffusion equation with a variable diffusivity is solved numerically by a finite difference method. The variation of the temperature distribution within the ice sheet is given as a function of time.
