The North Slope coastal plain represents a unique landscape that is characterized by permafrost and an immense number of freshwater lakes of varying sizes and depths. These lakes provide habitat for fish and wildlife species, support subsistence resources for use by local populations, and serve as freshwater supply for industrial development. The ability of resource managers to effectively balance these uses depends on our understanding of the capacity of these lakes to serve as water storage and as well as our understanding of their function as habitat.

The primary result of this project is a GIS data set that identifies winter liquid water availability within lakes throughout the North Slope coastal plain. Each lake within the North Slope coastal plain study area was classified for the presence of liquid water below ice using synthetic aperture radar (SAR) data for late winter. This data set represents a one-time “snapshot” of winter liquid water availability as determined through the analysis of 36 SAR images that were acquired during April 2009. Spatial resolution of the SAR imagery is 25m. Orthorectification accuracy of SAR images varied consequently a 50m buffer was evaluated as part of accuracy evaluation to account for horizontal registration error. Final overall classification accuracy was determined using 18,753 bathymetric locations from 105 lakes. Overall classification accuracy of these bathymetric locations as frozen/unfrozen (inferred from depth) was 89%.
