Notes:

(1)  Ice internal pressure or stress (Pa m) is the integrated pressure across the vertical thickness of a layer of ice. It is produced when concentrated ice reacts to external forces such as wind and ocean currents.

(2)  This is the Julian day of the year that surface melt begins.

(3)  This is the Julian day of the year that surface freeze begins.

(4)  This is a metric that quantifies the wave-induced mechanical fatigue on the sea-ice pack (0 means broken, 1 means solid). This metric only makes sense in the presence of sea ice.
