More specifically, the ice-cover map layer from 8 January 2014 was subtracted from the map layers from 1 February 2014 and 25 February 2014. The results showed that almost all cracked/flooded areas were changed from consolidated ice cover and connected to the shore (Figure 16), with the cracked/flooded areas increasing from 5.6% to 11% of total ice cover between 1 February and 25 February 2014.
