From December 2014 (Figure 17a) to January 2015 (Figure 17b), there was a decrease in the consolidated ice cover along the Slave River Delta channel, particularly in the river section from Jean River to Big Eddy. Since the repeat cycle of the RADARSAT-2 satellite is 24 days, observations recorded by the satellite can account for some characteristics as well as progressions of river ice dynamics within 24-day cycles. The 24-day accumulation of freezing day degrees (FDD) showed that the cumulative FDD on 10 December 2014 was higher than that of 3 January 2015 (Figure 19).
