Table 2 



MELTING PEICENTAGES OF WINTER ICE AND AGE OF POLAR ICE 

 FOR SUMMER SURFACE COVERAGE OF 90 PERCENT 



Assuming a loss of 10 percent by current outflow, the melting 

 percentages of the winter ice and the average age of the polar 

 ice are given for different percentages of areal melting of 

 polar ice.
