The paper establishing the VP-type behaviour is a very early Hibler, something 
like 1978. Averaging across floes is crucial, as is the large-scaleness.

For a time before, people tried to treat sea ice as elastic (which it is, 
considered as a single flow) but this is completely intractable (you have to 
keep histories).
