In view of the fact that sea ice strength is a function of ice salinity, a geometric model of the growth of ice is shown indicating the entrapment of brine between platelets. The upper surface and all other depths become less saline with time as the ice sheet thickens. So ice strength is a function of depth and time among other factors. Simplified and empirical expressions are given for calculating the actual value of the relative brine volume, necessary to predict sea ice strength. This brine volume shows a large and non-linear variation with temperature. The greater loading effect is produced by low rather than high ice speed, with which oscillating-type failure of piles also is associated. The ice types: fine grained, medium grained, center, and bottom, each with its own initial salinity, are all found in the Arctic Ocean, and must be taken into consideration.
