Chen, Min, Rowland, Joel C., Wilson, Cathy J., Altmann, Garrett L., and Brumby, Steven P., 2014, Temporal and spatial pattern of thermokarst lake area changes at Yukon Flats, Alaska: Hydrological Processes, v. 28, no. 3, p. 837-852.
To better understand the linkage between lake area change, permafrost conditions and intra-annual and inter-annual variability in climate, we explored the temporal and spatial patterns of lake area changes for a 422?382-ha study area within Yukon Flats, Alaska using Landsat images of 17 dates between 1984 and 2009. Only closed basin lakes were used in this study. Among the 3529 lakes greater than 1 ha, closed basin lakes accounted for 65% by number and 50% by area. A multiple linear regression model was built to quantify the temporal change in total lake area with consideration of its intra-annual and inter-annual variability. The results showed that 80.7% of lake area variability was attributed to intra-annual and inter-annual variability [...]
