 Explanation of Sea Ice Symbology Used in Figures 1-12 



C = Total ice concentration in the area in tenths. 



Ca^b^c = Concentration of thickest (C a ), 2nd thickest (C^), and 3rd thickest (C c ). 

 s a s b s c = Stage of development of thickest (S a ), 2nd thickest (St,), and 3rd thickest (S c ). 

 ~C = Concentration of ice within areas of strips and patches. 

 F a F b F c = F,oe size of thickest (F a ), 2nd thickest (F^), and 3rd thickest (F c ).
