Ice formation and breakup on Arctic rivers strongly influence river flow,sedimentation, river ecology, winter travel, and subsistence fishing and huntingby Alaskan Natives. We use time-series ground imagery ofthe Meade River toexamine the process at high temporal and spatial resolution. Freezeup fromcomplete liquid cover to complete ice cover ofthe Meade River at Atqasuk,Alaska in the fall of 2008 occurred in less than three days between 28 Septemberand 2 October 2008. Breakup in 2009 occurred in less than two hours between23:47 UTC on 23 May 2009 and 01:27 UTC on 24 May 2009. All times in UTC.Breakup in 2009 and 2010 was ofthe thermal style in contrast to the mechanicalstyle observed in 1966 and is consistent with a warming Arctic.
