Abstract : IT IS POSSIBLE TO DETERMINE THE PHASE RELATIONS IN SEA ICE FROM ION CONCENTRATION MEASUREMENTS ON THE UNFROZEN BRINE. From the composition and structure such physical properties as strength, thermal conductivit and permeability may be calculated. All of the physical properties of sea ice change rapidly after freezing begins until the temperature of the ice is about -5 C. The anomalous behavior of strength, density, coefficient of volume expansion, specific heat, latent heat, and conductivity can be explained by the continuous phase changes taking place at all temperatures. The heat of crystallization of solid salts is found to be small but not negligible in comparison with other thermal effects. (Author)
