SPECIFIC HEAT OF SEA ICE, B. T. U.Ab./°F. 



There will be a corresponding effect on apparent heat of fusion of 

 the ice, as shown by the following table : 



HEAT REQUIRED TO MELT 1 POUND OF SEA ICE, B. T. U. 



The heat of fusion of pure ice, the amount of heat required to melt 

 one pound of ice at 32° F., is 142 B. t. u. 



The coefficient of expansion of sea ice will likewise be affected. 

 Since water expands nearly 10 percent on freezing, while ice contracts 

 on further cooling, the net expansion or contraction of sea ice con- 

 taining brine cells will be a complicated function of temperature and 

 salinity, as indicated in the following table :
