in a manner consistent with the existing prognostics
will ensure its availability in existing modules. Careful consideration
should be given to where the new prognostic will be updated in the time
stepping in the driver file 
. It might be wise to add the
prognostic to the history file for output. It is necessary to add the
new prognostic to the restart file if the exact restart character of
the sea ice model is to be maintained (crucial for coupled model
integrations). It might be wise to test the new prognostic in Active
Ice Only (AIO) runs first, before attempting to run fully or partially
coupled to other components.
