Recent lake ice-out phenology within and among lake districts of Alaska, U.S.A.
lake districts of Alaska
2014/4/2
The timing of ice-out in high latitudes is a fundamental threshold for lake ecosystems and an indicator of
climate change. In lake-rich regions, the loss of ice cover also plays a key role in landsca...
