High-Resolution Permafrost Maps for Western Alaska

Map of permafrost presence and locations of elevation extremes.

High-resolution elevation maps, based on LiDAR, were used to model the distribution of permafrost across the Y-K Delta of Alaska. The map insets show detail for areas of relative high elevation (left) and low elevation (right).

ABoVE: Permafrost Measurements and Distribution Across the Y-K Delta, Alaska, 2016

This dataset provides field observations of thaw depth and dominant vegetation types, a LiDAR-derived elevation map, and permafrost distribution and probability maps for an area on the coastal plain of the Yukon-Kuskokwim (Y-K) Delta, in western Alaska, USA. These high-resolution permafrost maps support landscape change analyses and assessments of the impacts of climate change on permafrost in this region of high biological productivity, critical wildlife habitats, and subsistence-based human economy.

The Arctic-Boreal Vulnerability Experiment (ABoVE) is a NASA Terrestrial Ecology Program field campaign based in Alaska and western Canada. Research for ABoVE will provide a foundation for improving the analysis and modeling capabilities needed to understand and predict ecosystem responses and societal implications.
