The continuous permafrost landscape of northern Alaska varies in ground-ice content and the size and density of lakes. Lakes selected for study align with this physiographic, as well as with the climatic, variability and an lake observation program, CALON, show in (A). A late winter SAR image shows the distribution of both bedfast and floating ice lakes within the Fish Creek watershed, which will serve as the focus area for geophysical measurement, experimental manipulation of lakes, and modeling (B). A 9-year late winter ice regime classification shows high abundance of transitional ice lakes in the lower Fish Creek watershed where LiDAR acquisition was completed in 2013, providing the data for hydrologic modeling of a catchment with bedfast, transitional, and floating ice lakes (C).
