| Summary: | 39 pages Sentinel-2 optical imagery was used to track changes in lake area in a highly dynamic area of the Yukon Flats, Alaska over 2019-2023. Specific questions this research addresses include: how spatially consistent is the variability in water area? Why are certain lakes far less seasonally variable than others? How consistent is the temporal and spatial variability in the water area from year to year? Seasonal lake area fluctuations follow a similar progression from year to year. The seasonal maxima in lake extent are very pronounced for smaller water bodies in 2021 (20% higher average maximum lake area, 40% lower average minimum lake area) than larger water bodies. On average 2019 had the highest mean lateral change along lake shorelines while 2023 had the lowest. |
