	25	!! Introduction : \|
	26	!! -------------- \|
	27	!! Every ice-covered grid cell is characterized by a series of state \|
	28	!! variables. To account for unresolved spatial variability in ice \|
	29	!! thickness, the ice cover in divided in ice thickness categories. \|
	30	!! \|
	31	!! Sea ice state variables depend on the ice thickness category \|
	32	!! \|
	33	!! Those variables are divided into two groups \|
	34	!! * Extensive (or global) variables. \|
	35	!! These are the variables that are transported by all means \|
	36	!! * Intensive (or equivalent) variables. \|
	37	!! These are the variables that are either physically more \|
	38	!! meaningful and/or used in ice thermodynamics \|
